delete these files. If they are deleted using Windows, this may prevent further access from a Mac.
• If an SMB connection is used with OS X 10.3.9, the names of mounted volumes may appear as unreadable
characters in Finder and other applications. This is not a problem with the filename or data.
• With OS X 10.5 to 10.5.6, Spotlight searches are not supported over AFP connections. Use SMB connections or
upgrade to OS X 10.5.7 or later.
• The TeraStation belongs to the default zone in AppleShare; the zone cannot be specified.
• When files are copied to the TeraStation or to a USB drive connected to the TeraStation, file information such as
date created, date modified, and other date information may be updated or changed.
• During a file transfer, if settings are changed, the file transfer operation may be aborted.
• File copying to the TeraStation is protected by a journaling file system. If the Ethernet cable is disconnected or a
power outage occurs while copying data, the following may occur:
- Preset data such as the TeraStation name, users, and groups may be erased.
25
- An incomplete file may be copied and the file can no longer be deleted. If this happens, restart the TeraStation,
delete the file, and perform the copy operation again.
Recycle Bin
To protect your data from accidental deletion, you may configure your TeraStation to use a recycle bin instead of
deleting files immediately. The recycle bin will only work with SMB connections. To empty the recycle bin, click File
Sharing - Folder Setup - Empty Recycle Bin in Settings.
Notes:
• You can prevent guests and other users from emptying the trash by navigating to File Sharing - SMB - Recycle Bin
Permissions and select "Administrator only".
• If you use macOS, select "Exclude Mac OS temp files from recycle bin" option. If this setting is changed, files in the
recycle bin may be corrupted.
Read-Only Shares
By default, new shares are set with read and write access, but you may change the attribute to Read Only in Attribute.
Read-only shares and HFS Plus-formatted USB drives will have "(Read Only)" added to comments in Explorer.
Note: Configure read-only file attribute in Settings. Configuring them from within Windows is not supported and
may cause unexpected behavior.
Hidden Shares
If hidden shares are enabled, shared SMB folders will not be displayed in Network, and only certain users are allowed
to access them. To hide a shared SMB folder, follow the procedure below.
1 In Settings, navigate to File Sharing - Folder Setup and choose a shared folder or a USB drive to configure
hidden shares.
2 Select the "Hidden Share (SMB Only)" checkbox and click OK.
Notes:
• If protocols other than "SMB" or "Backup" under "LAN Protocol Support" are enabled, the hidden shares option
will be grayed out and cannot be selected.
• Configure hidden share attribute in Settings. Configuring them from within Windows is not supported and may
cause unexpected behavior.
To access a hidden folder, open File Explorer in your computer and enter "\\TeraStation name\Shared folder name$\"
for the name. For example, if the TeraStation name is "TSXXX001" and the shared folder name is "share", enter "\\
TSXXX001\share$\" to open it.
Configuring Users
Adding a User
Note: The TeraStation can register a maximum 300 of users, which includes the default users "admin" and "guest".
1 In Settings, click File Sharing.
26
2 Click to the right of "Users".
3 Click Create User.
27
4 Enter the desired settings, then click OK.
Notes:
• Usernames may contain up to 128 alphanumeric characters, hyphens (-), underscores (_), periods (.), and symbols
!, #, &, @, $, *, ^, %. The first character should not be a symbol.
• The user ID should be a number from 1000 to 1999. Each user ID should be unique. If this field is left blank, a user
ID is assigned automatically.
• Do not duplicate user IDs, group IDs, usernames, or group names. Each should be distinct and unique.
• User descriptions may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. The
first character should not be a symbol or space.
• Passwords may contain up to 20 alphanumeric characters and the following characters: - _ @ ! # $ % & ' ( ) * + , . / ;
< > = ? " [ ] ^ { } | ~. The first character should not be a symbol other than an underscore (_).
• Use the same username and password for both Windows and the TeraStation or you may not be able to access
shared folders.
• Do not use any of the following words for a username as these words are reserved for internal use by the
TeraStation: adm, admin, administrator, all, apache, bin, daemon, disk, ftp, ftpuser, guest, halt, hdusers, kmem,
lp, mail, man, mysql, news, nobody, nogroup, none, operator, root, shadow, shutdown, sshd, sync, sys, tty, users,
utmp, uucp, www
28
Importing User Information
You can import users in File Sharing - Users by clicking Import CSV File.
Format for user data: Username (required), password (required), and user description (optional).
Example 1: Importing usernames, passwords, and comments
username1,password1,comment1
username2,password2,comment2
username3,password3,comment3
Example 2: Importing usernames and passwords
username1,password1,
username2,password2,
username3,password3,
Guidelines:
• Use commas (,) as separators. Do not put spaces before or after commas. If you don't want user descriptions, use
a comma after password at the end.
• If a line has an incorrect format, the user on that line will not be registered.
• If a username already exists, the new user information will overwrite the old information.
• Do not use commas (,) in the username, password, or user description.
Note: Imported users are added to the "hdusers" group automatically.
Adding a Group
1 In Settings, click File Sharing.
2 Click to the right of "Groups".
29
3 Click Add Group.
30
4 Enter the desired settings, then click OK.
Notes:
• Group names may contain up to 20 alphanumeric characters, hyphens (-), underscores (_), and periods (.). The
first character should not be a symbol other than an underscore (_).
• Group descriptions may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. The
first character should not be a symbol or space.
• If the group ID field is left blank, a group ID is automatically assigned. Use numbers between 1000 and 1999 to set
a group ID manually. Don't use duplicate group IDs.
• You may register up to 300 groups with the TeraStation.
• If you are logged in as a member of the general users group, you can only change your own password. If you're
logged in as an administrator, you can change any settings, including other users' passwords. If you are logged in
as a member of the power users group, you can create and edit shared folders, users, and groups.
• Do not use any of the following words for a group name as these words are reserved for internal use by the
TeraStation: adm, admin, administrator, all, apache, bin, daemon, disk, ftp, ftpuser, guest, halt, hdusers, kmem,
lp, mail, man, mysql, news, nobody, nogroup, none, operator, root, shadow, shutdown, sshd, sync, sys, tty, users,
utmp, uucp, www
31
Configuring Access Restrictions
You may restrict access to specific shared folders, including external USB drives.
Notes:
• Access restrictions can be set separately for each shared folder, but not for folders within the shared folders.
• Configure access restrictions through Settings. Configuring access restrictions through Windows is not supported
and may cause unexpected behavior.
• You can also configure users, groups, and shared folders from Easy Admin by clicking Access Restrictions.
• Shared folders with limited access can still be used as backup destinations.
• If you change access restrictions for a user or group while they are accessing files, unexpected behavior may
result.
Local Users and Groups
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Click the shared folder that you want to set access restrictions for.
4 Click Edit.
5 Enable "Access Restrictions".
6 Select the level of access for the user or group you added.
32
: Read and write access allowed : Read access allowed : Access prohibited
7 Click OK.
Notes:
• The example above shows access restriction by user. To restrict access by group, click the Local Groups tab and
select group permissions.
• If both read-only and read and write permissions are given to a user, the user will have read-only access. The most
restrictive access always applies.
• For an access-restricted shared folder, if you change the access restrictions of all users and groups from read and
write or read only to access prohibited from the user or group list page in Settings, that shared folder can only be
accessed by admin users and groups.
Active Directory
If there is an Active Directory environment, the TeraStation will use account information from the Active Directory
domain controller to set access restrictions for TeraStation's shared folders. There is no need to perform individual
account management for the TeraStation. If multiple TeraStations are installed on the network, the account
information is centrally managed in Active Directory, greatly reducing the operations required for installation and
management.
Notes:
• If usernames or group names from Active Directory include multibyte characters, you will not be able to
configure access restrictions for them.
• The TeraStation supports a domain environment with a maximum of 1000 users and 1000 groups.
1 In Settings, click Network.
2 Click to the right of "Workgroup/Domain".
3 Click Edit.
33
4 Select "Active Directory", then click Next.
5 Click Yes.
6 Enter the desired settings, then click OK.
7 Click to the right of "Folder Setup".
34
8 Click a shared folder that you want to set access restrictions for.
9 Click Edit.
10 Enable "Access Restrictions".
11 Select the level of access for the user or group.
: Read and write access allowed : Read access allowed : Access prohibited
12 Click OK.
Notes:
• To have the TeraStation join an Active Directory domain, configure it to use a DNS server that can resolve names
for the Active Directory domain.
• After building an Active Directory domain, the administrator password for joining the domain must be changed
at least once, or joining the Active Directory domain will fail.
• The DNS name and NetBIOS name of Active Directory domains should be identical.
• If both read-only and read and write permissions are given, the user will have read-only access. The most
restrictive access setting will apply.
• If there is a difference of more than 5 minutes between the TeraStation's clock and the domain controller's clock,
joining the domain or authenticating domain users and groups may fail. For best results, use an NTP server to set
the time for all network devices.
• To use the TeraStation as a member server in an Active Directory domain, the TeraStation should be logged in to
the domain and accessed from a computer that is not a member of the domain with a valid domain account.
• If the TeraStation is a member server of an Active Directory domain, you cannot connect as a guest user via AFP.
• If your TeraStation is a member server in an Active Directory domain and you change the authentication method
to "Workgroup", the account on the domain controller will not be deleted automatically.
• If FTP is enabled, local and domain group access restrictions from the AD network do not work. Use user access
restrictions instead.
35
• For an access-restricted shared folder, if you change the access restrictions of all users and groups from read and
write or read only to access prohibited from the user or group list page in Settings, that shared folder can only be
accessed by admin users and groups.
NT Domain
In an NT domain environment, the TeraStation uses account information from the NT domain server to set access
restrictions for files and folders on the TeraStation. There's no need to perform individual account management for
the TeraStation. If multiple TeraStations are installed on the network, the account information is centrally managed
in the NT domain, greatly reducing the operations required for installation and management.
Note: The TeraStation supports a NT domain environment with a maximum of 1000 users and 1000 groups.
1 Create an account on the domain controller for the TeraStation.
2 In Settings, click Network.
3 Click to the right of "Workgroup/Domain".
4 Click Edit.
5 Select "NT Domain", then click Next.
Note: To use Active Directory from Windows 2000 or Windows Server 2003, select "Active Directory" instead of
"NT Domain".
6 Click Yes.
36
7 Enter settings and click OK.
8 Click to the right of "Folder Setup".
9 Click a shared folder for which you want to set access restrictions.
10 Click Edit.
11 Enable "Access Restrictions".
12 Select the level of access for the domain user or group.
: Read and write access allowed : Read access allowed : Access prohibited
13 Click OK.
37
Notes:
• If you change the TeraStation's name, you will no longer be able to use domain users and groups or access
restrictions. To repair this, rejoin the domain.
• If both read-only and read and write permissions are given to a user, the user will have read-only access.
• If a domain username is more than 20 bytes long, the TeraStation truncates it to 20 bytes.
• To use the TeraStation as a member server in an NT domain, the TeraStation should be logged in to the domain
and accessed from a computer that is not a member of the domain with a valid domain account.
• If the TeraStation is a member server of an NT domain, you cannot connect as a guest user via AFP.
• When you change the user or group settings on the domain controller, these changes may not take effect
immediately on the TeraStation until it is rebooted.
• If your TeraStation is a member server in an NT domain and you change the authentication method to
"Workgroup", the account on the domain controller will not be deleted automatically.
• If FTP is enabled, local and domain group access restrictions from the NT domain network do not work. Use user
access restrictions instead.
• For an access-restricted shared folder, if you change the access restrictions of all users and groups from read and
write or read only to access prohibited from the user or group list page in Settings, that shared folder can only be
accessed by admin users and groups.
User Authentication with an External SMB Server
TeraStations on your network can be linked to an external authentication server for centralized management of user
accounts and passwords. The authentication server should be another TeraStation or a LinkStation. Other external
SMB authentication servers are not supported.
Notes:
• Disable SMB2 before using external authentication.
• Access restrictions for local users and groups will still apply to shared folders if an external SMB server is used for
authentication.
• The procedure below contains methods to automatically register external users. You can also manually add
external users by converting them from local users. Refer to the "Converting Local Users into External Users"
section below for more details on converting local users.
1 In Settings, click Network.
2 Click to the right of "Workgroup/Domain".
3 Click Edit.
38
4 Select "Workgroup" and click Next.
5 If a prompt appears, click Yes.
6 Enter a workgroup name. Select "Authenticate local and external SMB server users" and enter the SMB server's
IP address. You can also specify a server from another subnet.
7 If "Automatically register users who access TeraStation folders" is checked, users that access any of the
TeraStation's folders will be automatically registered as external users. This process only applies with folders
that have access restrictions disabled. After new external users are added, disable this option to limit the
number of authenticated user accounts.
8 If "Restrict user registration to a single folder" is checked, the TeraStation will automatically create a read-
only shared folder. Enter the shared folder name. Users that access this specific folder will be automatically
registered as external users. If this setting is deselected at a later time, the TeraStation will automatically
remove the folder.
Note: Connect to the authentication folder via SMB, not FTP or AFP. Automatic user registration may not
work with OS X 10.8 (or later) the first time. If this occurs, try rebooting the TeraStation then access the
authentication shared folder again.
9 Click OK to save any changes. When saving changes to the external authentication server settings, you may
not to convert all current local users to external users. If a local user is converted to an external user, their user
39
information (including passwords) will be removed from the NAS. External users cannot be reverted to local
users.
10 Click to the right of "Folder Setup".
11 Click a shared folder to set access restrictions on.
12 Click Edit.
13 Enable "Access Restrictions".
14 Click on the External Users tab and select the level of access for each external user.
: Read and write access allowed : Read access allowed : Access prohibited
15 Click OK.
Notes:
• Users that are automatically registered belong to the "hdusers" group. They can be added to other groups from
within group settings. Added users will be listed in "Users" - "External Users". To delete a user that was registered
automatically, select that user and click Delete External User.
• If both read-only and read and write permissions are given to a user, the user will have read-only access.
• OS X 10.4 or earlier and Windows Server 2012 are not supported with external authentication.
• To access access-limited shared folders from OS X 10.7, use AFP instead of SMB; under "LAN Protocol Support",
check "AFP (Mac)" on the destination folders to use AFP and click OK.
• If access restrictions are set for users and groups from the authentication server, guest and anonymous
connections will not be possible with AFP connections.
• FTP connections do not support authentication with an external SMB server.
40
• If using a Windows PC for external authentication, the default Windows SMB security settings may need to be
changed. An easy way to do this is to run the File Sharing Security Level Change Tool, available from this product's
download page on the Buffalo website. This utility will let you easily change or restore your Windows security
settings to work with external authentication.
• If you change all users' and groups' access attributes for the access-restricted shared folder, from read and
write or read only to access prohibited in the user or group list page of Settings, that shared folder can only be
accessed by admin users and groups.
Converting Local Users into External Users
If using an external SMB server for authentication, you may convert any local users into external users. This way, the
TeraStation will have a user list that matches the users in the external SMB server, and access restrictions for this
TeraStation's shared folders may be assigned to the converted "external" users.
Follow the procedure below to convert a local user into an external user. If a local user is converted, their user
information (including passwords) will be removed from the TeraStation. External users cannot be reverted to local
users.
Note: External authentication should be enabled before local users can be converted. For more information on
external authentication, refer to the "User Authentication with an External SMB Server" section.
1 In Settings, click File Sharing.
2 Click to the right of "Users".
3 In the user list screen, check any users to be converted to an external user, then click Convert to External User.
4 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
Converted users are displayed under the "External Users" tab. You can then configure access restrictions for external
users.

Chapter 4 Managing Storage
RAID Modes
TeraStations support many types of RAID. The type of RAID arrays available for use depends on how many drives are
installed in your TeraStation.
Notes:
• If you change the RAID mode, all data on the array is deleted. This is true for every procedure in this chapter.
Always back up any important data before performing actions that affect your RAID array.
• Hard drive capacity is shown in Settings in actual gigabytes. The Properties window in Windows may show GiB
instead, which will be a smaller number.
• After the RAID mode is changed (except when creating a RAID 0 array or JBOD), the TeraStation performs a RAID
check that will take about 10 hours per TB. File transfers are slower during this period. While the I17 message is
displayed on the LCD panel, do not turn off the TeraStation. If you do, the RAID check starts over.
• If the TeraStation is restarted or shut down while changing the RAID mode, the message displayed on the LCD
panel will change from I46 or I47 to I18.
• RAID 61 and 60 are only available for 8-drive models; RAID 51 and 50 are available for 8 and 6-drive models; RAID
5, 6, and 10 are available for 8, 6, and 4-drive models.
RAID 6
RAID 6 arrays are available for TeraStations with 4 or more hard drives. RAID 6 combines 4 or more drives into a
single array. The usable space is equal to the sum of the capacity of all drives minus the capacity of two drives. For
example, if 4 drives are combined into a RAID 6 array, the usable space is the sum of the capacity of 2 drives. If 2
drives in the array are damaged, you can recover data by replacing them. If 3 or more drives are damaged, your data
is lost.
RAID 61
RAID 61 arrays are available for TeraStations with 8 or more drives. In this mode, two RAID 6 arrays are mirrored in a
RAID 1 array. 8 drives in a RAID 61 array have a usable capacity of 2 x the capacity of the smallest drive.
RAID 60
RAID 60 arrays are available for TeraStations with 8 or more drives. In this mode, two RAID 6 arrays are combined in a
RAID 0 array. 8 drives in a RAID 60 array will have a usable capacity of 4 x the capacity of the smallest drive.
RAID 5
RAID 5 arrays are available for TeraStations with 3 or more hard drives. RAID 5 combines 3 or more drives into a
single array. The usable space is equal to the sum of the capacity of the hard drives minus the capacity of one drive.
For example, if 4 drives are combined into a RAID 5 array, the usable space is the sum of 3 drives. If one drive in the
array is damaged, you can recover data by replacing the damaged drive. If two or more drives are damaged at the
same time, your data is lost.
42
RAID 51
RAID 51 arrays are available for TeraStations with 6 or more hard drives. In this mode, two RAID 5 arrays are
combined into a RAID 1 array. The total usable space for 6 drives in a RAID 51 array is 2 x the capacity of the smallest
drive. For 8 drives, the total usable capacity is 3 x the capacity of the smallest drive.
RAID 50
RAID 50 arrays are available for TeraStations with 6 or more hard drives. In this mode, two RAID 5 arrays are
combined into a RAID 0 array. The total usable space for 6 drives in a RAID 50 array is equal to 4 x the capacity of the
smallest drive. For 8 drives, the total usable space is equal to 6 x the capacity of the smallest drive.
RAID 10
RAID 10 arrays are available for TeraStations with 4 or more hard drives. In this mode, mirrored pairs of drives in RAID
1 arrays are combined into a RAID 0 array. The usable space is equal to the capacity of the smallest drive multiplied
by the number of hard drives divided by 2.
RAID 1
Combines 2 or more drives into a mirrored array. The available space in the array is the capacity of a single drive.
Identical data is written to each drive. If a drive is damaged, data can be recovered by replacing the damaged drive.
As long as one drive in the array remains undamaged, all data in the array can be recovered.
RAID 0
Combines 2 or more drives into a single array. The usable drive space is the total space of all drives used. This simple
RAID mode offers faster performance than RAID modes that include parity. If a single drive in the array fails, then all
data in the array is lost.
JBOD
This mode uses the hard drives inside the TeraStation as individual drives. The drive space you can use is the total
capacity of all drives in the TeraStation. If any drive is damaged, then the data on that drive is lost.
Working with RAID Arrays
To change RAID settings, navigate to Drives - RAID in Settings.
Using JBOD
With JBOD, each hard drive in the TeraStation is addressed separately. To put drives from an array into JBOD, follow
the procedure below.
1 In Settings, click Drives.
43
2 Click to the right of "RAID".
3 Click the array to delete.
4 Click Delete RAID Array.
5 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
6 Click OK when finished.
Once JBOD is configured, create shared folders on each drive to use them.
Changing RAID Mode
To change the RAID mode, first put the drives in JBOD.
1 In Settings, click Drives.
2 Click to the right of "RAID".
44
3 Click the array to delete.
4 Click Delete RAID Array.
5 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
6 Click OK.
7 Choose a RAID array.
8 Select a RAID mode and the drives to be used, then click Create RAID Array.
Note: Normally, after a RAID array is created, it is "resynced", which optimizes the array, making it more stable.
The resyncing process takes about 1 hour per terabyte of space in the array. File transfers will be slower
during this period, but the array will remain fully usable. The I17 message will be shown on the LCD display
during the resync. If you uncheck "Resync after creating the RAID array", the resync will be skipped. This is not
recommended for RAID 5 arrays, which should always be resynced. Resyncing is not needed for RAID 0 arrays.
If the TeraStation is rebooted during the resyncing process, the resync will begin again from the beginning.
45
9 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
10 Click OK when finished.
Notes:
• You can also configure RAID settings from Easy Admin.
• After changing the RAID mode, create a shared folder.
Configuring a Hot Spare
If you have a hot spare configured and an array fails, the TeraStation immediately switches over to the hot spare. To
use a hot spare, you need an extra drive that's not part of any array and a RAID 1, RAID 10, RAID 5, RAID 51, or RAID 6
array.
Notes:
• All data on the hot spare drive is deleted when it is configured as a hot spare and again when it changes from a
spare to a drive in the array.
• A hot spare cannot be configured for TeraStation models with only two hard drives. Use RAID 1 instead.
1 In Settings, click Drives.
2 Click to the right of "RAID".
3 Choose a RAID array.
46
4 Click Set as a hot spare.
5 Click Yes.
6 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
7 Click OK when finished.
Notes:
• To turn the hot spare back into a normal disk, choose Set as a normal disk.
• If a drive fails in the RAID array before it is rebooted, the hot spare will not automatically replace the failed drive.
In this case, follow the procedure below to repair the array.
(1) In Settings, navigate to Drives - Drives.
(2) Click the drive that was configured as a hot spare, then click Dismount Disk.
(3) Click Rediscover Disk.
(4) Navigate to Drives - RAID.
(5) Choose the RAID array to repair.
(6) Click the drive that was previously configured as a hot spare, then click Recover RAID Array.
This will rebuild the RAID array.
RMM (RAID Mode Manager)
With RMM, you can create or expand a RAID array without erasing the data on the drives.
Changing from JBOD to RAID 1
You must have at least two drives available in JBOD (not in a RAID array) to build the RAID 1 array with RMM.
1 In Settings, click Drives.
47
2 Click to the right of "RAID".
3 Choose a RAID array.
4 Set the RAID mode to "RAID 1".
5 Select the "Add a disk to RAID array with RMM. Your data will be preserved." checkbox.
6 Select the drive whose data will be saved from the drop-down list.
7 Select the drive to add to the RAID array.
8 Click Create RAID Array.
48
9 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
10 Click OK when finished.
Adding a Drive to an Existing RAID Array or Changing the RAID Mode While Adding
a Drive
You can add a drive to a RAID 1, RAID 5, or RAID 6 array. Drives in JBOD can be added to the RAID array.
Note: RMM can be used to expand an array by one drive per operation. To expand by two or more drives, RMM must
be performed multiple times.
1 In Settings, click Drives.
2 Click to the right of "RAID".
3 Choose a RAID array.
49
4 Select one drive to add to the RAID array. If changing the RAID mode, choose the desired mode for the array
from the drop-down list. If not, keep the scurrent RAID mode as is.
5 Click Change RAID Array.
6 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
7 Click OK when finished.
RAID Scanning
A RAID scan checks you RAID array for bad sectors and if it finds any, it automatically repairs them. Arrays other than
RAID 0 are supported. For best results, run a RAID scan regularly.
1 In Settings, click Drives.
2 Move the RAID scanning switch to the position to enable RAID scanning.
3 Click to the right of "RAID Scanning".
4 Click Edit.
50
5 Select when to run the scan and click OK.
Notes:
• Select the "Immediately" checkbox to run a RAID scan immediately.
• To stop a RAID scan, click Cancel RAID Scan.
Adding an External Hard Drive
Connecting an External Drive
Your TeraStation includes USB ports (the number of ports depends on your model), and you can connect external
drives to these ports. Once connected, they appear as shared folders on the TeraStation. Formatted drives are
detected automatically. Unformatted drives should be formatted in Settings.
After a USB drive is recognized, Windows adds "usbdisk x" in File Explorer, where "x" is the USB port which the hard
drive is connected.
Compatibility
The following USB devices are supported by the TeraStation:
• USB storage devices
• Card readers (except for card readers that can recognize two or more memory cards)
Buffalo external USB drives are recommended but DUB and DIU series drives are not supported.
Supported file systems for external drives are below:
• FAT32
• EXT3
• XFS
• NTFS
• HFS Plus (read-only)
Connect only one device to each USB port of the TeraStation. Some external drives with automatic power-on don't
turn on automatically when connected to the TeraStation. Use their manual power switch to turn them on. Be sure
to connect only one bus-powered drive at a time. If there is insufficient bus power for your USB drive, connect its AC
adapter. Note that only the first partition of a connected USB hard drive is mounted. Additional partitions are not
recognized. Do not connect bus-powered devices to the 2-drive TeraStation models.
Notes:
• Backup data from macOS may include characters that cannot be written to FAT16 or FAT32 drives such as ".DS_
Store". For best results, reformat the drive before using it as a backup target.
• If your USB 3.0 hard drive is not reconfigured after rebooting the TeraStation, unplug and reconnect it.
51
Dismounting Drives
If the TeraStation is powered on, dismount drives (internal and external) before unplugging them. You may
dismount external drives with the function button, or any drive from Settings. If the TeraStation is off, then all drives
are already dismounted and may be unplugged safely.
Note: Do not dismount internal drives while a RAID array is rebuilding or RMM is being configured. If you do, data on
the drives may be lost.
Dismounting with the Function Button
Hold down the function button for 8 seconds. The function button will light up blue for 30 seconds as your USB
drives are dismounted. When the dismount is finished, the function button's LED will turn off, then comes back on.

53
4 Click Check. You have the option of deleting information files from macOS during the check if desired.
S.M.A.R.T.
S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) monitors internal drives to detect and report
various indicators of reliability, in the hope of anticipating failures. When a failure is anticipated by S.M.A.R.T., the
user may choose to replace the drive to avoid outages and data loss. Follow the procedure below to check S.M.A.R.T.
information for the TeraStation's internal drives.
Note: S.M.A.R.T. information is only available for internal drives.
1 In Settings, click Drives.
2 Click to the right of "Drives".
3 Select a drive to check and click S.M.A.R.T.
4 The S.M.A.R.T. information for the drive will be displayed. Different information may be displayed depending
on the brand of drives in your TeraStation. Critical attributes are displayed in bold. Attributes with current value
54
less than or equal to the threshold value may be significant. If an attribute reports a failure, or has had one in
the past, it will be displayed in the status column.
Formatting Drives
Notes:
• Under some circumstances, data deleted when a drive is formatted can be recovered. To ensure that data is "gone
forever", a format might not be sufficient. See the "Erasing Data on the TeraStation Completely" section below.
• After a drive is formatted, the "% Used" and "Amount Used" in Settings will not be 0. This is because some drive
space is used for the system area.
1 In Settings, click Drives.
2 Select Drives to format an internal drive or USB Drives to format an external drive.
55
3 Select the drive or array to format, then click Format Disk.
4 Select a format type, then click Format.
5 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
6 Depending on the size and the formatted file system of your drive, the format may take several minutes or
several hours to complete. "Formatting" will be displayed on the LCD panel until the format is complete. Click
OK when finished.
Notes:
• Do not turn off or disconnect power to the TeraStation while formatting a hard drive.
• For drives of 2.2 TB or larger, make sure that the "GPT Partition" checkbox is selected.
56
Encrypting Drives
Internal drives (and arrays) can be encrypted with 128-bit AES during formatting. Encrypted drives and arrays are
then readable only from that specific TeraStation. To decrypt a drive or array, clear the "Encryption" checkbox and
format it again.
Media Cartridges
If configured as a media cartridge, an internal drive can be used as a removable storage device in the same way as
an external drive. Media cartridges can be unplugged and connected to a different TeraStation with all data intact.
To configure a drive as a media cartridge, select the "Media Cartridge" checkbox during formatting. To return it to its
original state, clear the "Media Cartridge" checkbox and reformat the drive.
Media cartridges do not support:
• RAID arrays
• LVM volumes
• Access restrictions
• Direct connection to a Windows computer
• Antivirus
Notes:
• Don't configure the boot drives (drives 1 and 2) as media cartridges.
• Configure media cartridges from the bottom drive up. For example, if your TeraStation has 4 drives, make drive 4
a media cartridge first, then drive 3 next.
57
• If the TeraStation fails to boot after drive 1 or 2 is replaced, remove any media cartridges, then replace them after
the TeraStation has booted.
Erasing Data on the TeraStation Completely
Under some circumstances, data from formatted drives can be recovered. The drive erasure process in this section
does a much more thorough job of erasing data. This procedure is recommended for removing all data from a drive
in a way that makes it nearly impossible to recover with current tools. The TeraStation will then be in the following
state:
• All drives in JBOD
• An empty shared folder on each drive
• All settings returned to their default values
• All logs deleted
If you remove a drive and then erase all data on the TeraStation, the LCD panel will show the E22 error message and
the number of the removed drive. You can still use the TeraStation.
Follow the procedure below to completely and permanently erase all data from your TeraStation.
1 In Settings, click Management.
2 Click to the right of "Restore/Erase".
3 Click Erase TeraStation.
4 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
5 All data on the TeraStation will be permanently erased.
Drive Quotas
You can set a drive quota to limit drive space for each user or group. You can also set a threshold. If the drive space
exceeds the configured threshold, an email notification will be sent. To configure email notifications for the drive
quota, refer to the "Email Notification" section in chapter 10.
Notes:
• When using quotas, disable the recycle bin or empty the trash folder often. The limited space includes the space
used for trash.
• Quotas apply per drive or per array. If a quota is set to 1 GB, each array or drive can use a maximum of 1 GB.
• Quotas cannot be set for external hard drives connected to the TeraStation and hard drives that are configured as
media cartridges.
58
• If both user and group quotas are configured for a user, the most restrictive quota will always apply.

disable LVM before use.
• If you click Show under "Volume List", the volumes will be listed on the screen and you can see if these volumes
are being used as iSCSI or NAS.
• Do not use any of the following words for the name of a volume as these words are reserved for internal use by
the TeraStation: array x, authtest, disk x, global, homes, info, lost+found, lp, mediacartridge x, msdfs_root, mt-
daapd, printers, ram, spool, usbdisk x. Any instances of "x" denote a number (for example: array1 or disk3)
• If an LVM volume could not be mounted, try restarting the TeraStation. If an issue still exists, delete and recreate
the LVM volume. Deleting the LVM volume will erase data on the volume.
Using the TeraStation as an iSCSI Device
Introduction
iSCSI is a protocol for carrying SCSI commands over IP networks. Unlike traditional SAN protocols such as Fibre
Channel, which requires special-purpose cabling, iSCSI can be run over long distances using existing network
infrastructure. Normal Windows formatting such as NTFS is supported.
Differences Between NAS and iSCSI
With iSCSI, the TeraStation is connected to a single computer, such as a server. Other computers on the network
access files on the TeraStation through the computer it's connected to. The TeraStation can be used as a local drive
from Windows Server. Features of Windows Server such as Active Directory can be used normally.
As a NAS, the TeraStation is a server, and computers (including other servers) on the network can access shared
folders on it directly. A separate server is not required, and features such as backup are built-in.
Network Configuration
Use gigabit or faster network equipment with iSCSI. For best results, a dedicated network for iSCSI is recommended,
separate from the regular network. Use static IP addresses for storage devices such as the TeraStation.
Installing a Connection Tool
Windows XP, Windows Server 2003
Before using any iSCSI equipment, download and install the iSCSI connection software "Microsoft iSCSI Software
Initiator" from the Microsoft website.
If using TeraStation 5000 series, you can also use Buffalo iSCSI Connection Tool to connect to an iSCSI hard drive.
Windows Vista or later, Windows Server 2008 or later
The Microsoft iSCSI Software Initiator is already installed on your computer. You don't need to download and install
it.
If using TeraStation 5000 series, you can also use Buffalo iSCSI Connection Tool to connect to an iSCSI hard drive on
except for Windows 10. If you are using Windows 10, use Microsoft iSCSI Software Initiator.
Creating an iSCSI Volume
To use the TeraStation as an iSCSI hard drive, create a volume first. Configure the TeraStation as described below.
63
Notes:
• If the volume settings are changed, all data on the volume will be erased. Before changing any settings, back up
any important data.
• The TeraStation can have up to 255 volumes, but we recommend creating no more than 32. Exceeding this
volume amount may cause irreparable damage to the unit.
• Do not use any of the following words for the name of a volume as these words are reserved for internal use by
the TeraStation: array x, authtest, disk x, global, homes, info, lost+found, lp, mediacartridge x, msdfs_root, mt-
daapd, printers, ram, spool, usbdisk x. Any instances of "x" denote a number (for example: array1 or disk3)
1 In Settings, click Drives.
2 If you want to specify a volume size or change it later, enable LVM by referring to the "Size Limits" section
above. LVM does not need to be enabled for a drive or array to be used as an iSCSI hard drive, as you can still
create an iSCSI volume from the entire drive or array. However, enabling LVM is recommended for drives or
arrays that will be used for iSCSI.
To use the whole drive or array as an iSCSI hard drive, proceed to the next step.
3 Move the iSCSI switch to the position to enable iSCSI.
4 Click to the right of "iSCSI".
5 Click Create Volume.
64
6 Enter a volume name, volume description, drive or array where a volume will be created, and volume size (if
you enabled LVM). Click OK when finished.
The volume size that you specify here can be changed later. To change the volume size, refer to the "Expanding
Volume Sizes" section below.
7 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
8 Click OK, then Close.
Note: If you click Disable Connection for the selected volume in Drives - iSCSI in Settings, the selected iSCSI volume
can no longer be accessed. If you click Enable Connection, the volume will become accessible from the iSCSI initiator
software.
Connecting or Disconnecting Volumes
There are two methods to connect or disconnect volumes. One uses the pre-installed Microsoft iSCSI Initiator on
Windows; the other uses Buffalo iSCSI Connection Tool. The method to use Buffalo iSCSI Connection Tool is available
only to customers with TeraStation 5000 series.
Note: By default, the IP address of the TeraStation is automatically assigned from a DHCP server. However, in this
case, if you turn off and restart the TeraStation, the IP address may be changed and the volumes on the TeraStation
may not be accessible. To avoid changing the IP address unexpectedly, using a static IP address for the TeraStation is
recommended.
Using Microsoft iSCSI Initiator

1 Error LED
Glows red if a drive has failed.
2 Status LEDs
The failed drive's status LED will be glowing a steady red. A drive with a red status LED is ready to hot-swap.
Notes:
• Do not unplug a drive whose status LED is green instead of red. Dismount it first or shut down the TeraStation
before swapping a working drive. If you remove the drive without properly dismounting it, data may be lost or
the TeraStation may malfunction.
• For the replacement drive, use a Buffalo OP-HDWR series drive for TeraStation 5000WR series and TeraStation
5000N series, a OP-HDH series drive for the TS5400RH, and a OP-HDS series drive for other TeraStation 5000 series.
The new drive should be the same size or larger. If a larger drive is used, the extra space will not be usable in a
RAID array.
• To avoid damaging the TeraStation with static electricity, ground yourself by touching something made of metal
before handling any sensitive electronic parts.
• After a drive is replaced, it will take about 30 minutes before normal file reading and writing are restored. Settings
may not be accessible during this period.

open. Swing the lock back down until it clicks into place.
9 Close the front cover.
10 When the replacement drive is recognized, the status LED will flash red and the I32 information message will
be displayed on the LCD panel.
Select the RAID array from Drives - RAID in Settings and click Delete RAID Array. In Drives - Drives, click Format
Disk to format the new drive. In Drives - RAID, choose the type of RAID array desired. Enter the confirmation
number and click OK. Create a shared folder before use.
Using a Hot Spare
If your TeraStation's drives are in a redundant RAID mode, and you have a hot spare enabled, a malfunctioning drive
in the array is replaced by the spare drive and the RAID array is rebuilt automatically. The status LED will continue
to glow red for the failed drive even after the RAID array is rebuilt with the hot spare. This section describes the
replacement process for a hard drive while the TeraStation is still on.
1 Open the front cover with the included key.
2 The failed drive's status LED will be glowing red. Push its unlock button and swing the lock mechanism out.
3 Pull out the drive cartridge and remove it from the TeraStation.
4 Insert the new drive into the empty slot. Slide the drive in with the locking mechanism open. Swing the lock
back down until it clicks into place.
5 Close the front cover.
6 When the replacement drive is recognized, the status LED will flash red and the I31 information message will
be displayed on the LCD panel.
7 Hold down the function button on the front of the TeraStation for 3 seconds until it beeps. The replacement
hard drive is automatically registered as a hot spare.
To use the replacement disk as a normal drive rather than a hot spare, navigate to Drives - RAID and click the
RAID array, select the new drive, and click Set as a normal disk.
Note: If a drive fails in the RAID array before it is rebooted, the hot spare will not automatically replace the failed
drive. In this case, follow the procedure below to repair the array.
(1) In Settings, navigate to Drives - Drives.
(2) Click the drive that was configured as a hot spare, then click Dismount Disk.
(3) Click Rediscover Disk.
(4) Navigate to Drives - RAID.
(5) Choose the RAID array to repair.
(6) Click the drive that was previously configured as a hot spare, then click Recover RAID Array.
This will rebuild the RAID array.
Replacing a Media Cartridge
Drives configured as media cartridges may be removed and moved to a different TeraStation for use. Before
unplugging the drive, dismount it in Settings or shut down the TeraStation.
88
Replacing a Non-Malfunctioning Hard Drive
Do not replace a hard drive that is not malfunctioning (unless it has been converted to a media cartridge).
If you must change a drive that is not malfunctioning, either first dismount it in Settings, referring to the
"Dismounting Drives" section above, or shut down the TeraStation before replacing the drive. If you need to replace
more than one drive at the same time, replace the drives one at a time to preserve your data. When replacing the
non-malfunctioning drive, the RAID array will function as below:
Operating in RAID 0 Mode
All data on the RAID array will be deleted after replacing the drive. You will not be able to use the TeraStation until
you delete and rebuild the RAID array with the new drive.
Operating in JBOD
All data on that hard drive will be deleted after replacing the drive. You will not be able to use the TeraStation until
you format the new drive.
Operating in a Redundant RAID Mode
If you are using a redundant RAID mode such as RAID 1, 5, or 6, the RAID array will be in degraded mode after
replacing the drive. You will not be able to use the TeraStation until you rebuild the RAID array with the new drive.
89
Chapter 5 Backup
Backing Up from the TeraStation
You can back up TeraStation folders to:
• A different folder on the TeraStation
• Another LinkStation on the network
• Another TeraStation on the network
You can also configure backup jobs from Easy Admin.
Preparing a Backup Destination
First, configure a folder as a backup destination.
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Choose the folder to set as a backup destination.
4 Click Edit.
5 Under "LAN Protocol Support", select the "Backup" checkbox.
90
6 Click OK.
7 Enter the desired characters into the backup device access key field and click OK.
Note: You may leave this field blank if you do not want a backup device access key, but for security reasons
we highly recommend entering one for the shared folder. If a backup device access key is configured for the
shared folder, that folder will not show up as a target for the backup source or destination when configuring a
backup job on another Buffalo NAS device unless it's entered. You may create multiple folders using different
backup device access keys for backup and replication, but only one access key can be used on the TeraStation.
Folders that are configured with a different access key cannot be used.
8 Click OK.
Notes:
• To back up data between Buffalo NAS devices on a network using jumbo frames, make sure that both devices are
configured to use identical (or similar) Ethernet frame sizes. If Ethernet frame sizes are significantly different, the
backup job may not be properly performed. In such a case, select the default frame size (1500 bytes).
• You can also specify a hostname by a fully qualified domain name (FQDN).
• Windows-based TeraStations with multibyte characters in the hostname may not be detected as a backup
destination, and folders in these devices cannot be used as backup destination folders.
Backing Up to a Buffalo NAS Device on Another Network When Connected via VPN
You can back up to a Buffalo NAS device on another network as long as the two networks are connected by a VPN.
Follow this procedure to enter the IP address or hostname of the destination Buffalo NAS device.
1 In Settings, click Backup.
2 Click to the right of "Backup".
91
3 Click List of LinkStations and TeraStations.
4 Click Add under "Off-subnet Devices", enter the IP address or hostname of the destination LinkStation or
TeraStation, and click Close.
92
Configuring a Backup Job
1 In Settings, click Backup.
2 Click to the right of "Backup".
3 If you configured the backup device access key, click Set. If you didn't, proceed to step 5.
4 Enter the backup device access key and click OK.
93
5 Click Create New Job.
94
6 Select backup settings such as date and time to run.
The following types of backup jobs may be selected:
Type Files included
Normal backup
All files in the source will be backed up to the destination. You can specify
how many backup versions to keep from 1–400, or select "Unlimited" to keep
all backups until the drive is full. If a specific number of backup versions is
specified, the backup destination folder should be on the same TeraStation
that the backup job is configured from, or on an external USB drive attached
to that TeraStation.
Overwrite (incremental)
The first time the backup job runs like a normal backup. In subsequent
backups, files added to the source as well as files deleted from the source are
kept in the backup folder.
Overwrite (differential)
The first backup job runs like a normal backup. As each additional backup
job runs, files are added to and deleted from the backup folder. The backup
destination folder is always the same size as the backup source folder.
95
Type Files included
Management backup
Each time a backup is executed, management information is stored, and
only files that have changed are copied or deleted. Data is retrieved from the
previous backup file for files that were not changed. This is useful for making
backups with limited space or for referencing status at a particular point in
time (for use for data snapshot applications). The destination folder for a
management backup should be a local folder on this TeraStation or on a USB
drive attached to it. The destination folder will be set to read-only. Do not use
folders from drives formatted with FAT.
You can specify how many backup versions to keep from 1–400, or select
"Unlimited" to keep all backups until the drive is full. The backup destination
folder should be on the same TeraStation that the backup job is configured
from, or on an external USB drive attached to that TeraStation.
7 Click Add.
8 Click Browse under "Backup Source Folder Name".
9 Select the shared folder that will be the backup source, then click OK.
10 Click Browse under "Backup Target Folder Name".
96
11 Select the backup destination and click OK.
12 Click OK. Jobs will be added to the backup list.
Note: Up to 8 backup jobs can be configured.

Replication
Replication copies all data from a share to a share on a different TeraStation. This is an easy way to configure a
reliable system to provide data protection in the event your main TeraStation fails. To configure replication, connect
an Ethernet cable to the LAN port of each TeraStation and follow the procedure below.
Notes:
• For best results, use static IP addresses for connecting both replication TeraStations (source and destination).
• Replication source data is copied to the replication destination folder with a differential overwrite. Any data that
is not in the replication source will be overwritten.
Preparing a Replication Destination
First, configure a folder as a replication destination.
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Choose the folder to set as a replication destination.
4 Click Edit.
5 Under "LAN Protocol Support", select the "Backup" checkbox.
100
6 Click OK.
7 Enter the desired characters into the backup device access key field and click OK.
Note: You may leave this field blank if you do not want a backup device access key, but for security reasons we
highly recommended entering one for the shared folder. If a backup device access key is configured for the
shared folder, that folder will not show up as the replication destination when configuring a replication task
on another Buffalo NAS device unless it's entered. You may create multiple folders using backup device access
keys for backup and replication, but only one access key can be used on the TeraStation. Folders that are
configured with a different access key cannot be used.
8 Click OK.
Configuring a Replication Task
1 In Settings, click Backup.
2 Click to the right of "Replication".
101
3 Click Edit.
4 If you configured the backup device access key, click Set. If you didn't, proceed to step 5.
5 Enter the backup device access key and click OK.
102
6 Click Add.
7 Click Browse under "Replication Source".
8 Select the shared folder that will be the replication source, then click OK.
9 Click Browse under "Replication Target".
103
10 Select the shared folder that will be the replication destination, then click OK.
11 Click OK, then Yes.
Notes:
• A maximum of 64 shared folders can be configured for replication.
• Replication can also be used to copy all data from a share to a share on an attached external drive. Format
the drive with ext3 or XFS before using it for replication. Drives with FAT32 partitions are not supported with
replication.
• You can select the first and second level of shared folders and USB drives connected to the TeraStation as the
replication source. Folders whose names contain more than 80 alphanumeric characters cannot be selected.
• Don't use the same TeraStation for both failover and replication, or replication and Time Machine.
• Don't configure replication from one source folder to multiple destination folders.
• If a network problem causes a replication error, unsynced data may be shown as "0" even though replication is
incomplete. Click Resync to recover from the replication error. All files from the source folder will be copied to the
destination folder.
104
Failover
With failover, two TeraStations are connected to the network for redundancy. If an issue renders the main
TeraStation inaccessible, operation automatically switches to the backup TeraStation.
Switches automatically if failure occurs.
Data on both TeraStations stays up-to-date.
BackupMain
Failover will activate during any of the following situations:
• The backup TeraStation cannot detect the main TeraStation within a specified time
If the backup TeraStation has not received a packet from the main TeraStation within a specified time, the backup
TeraStation considers the main TeraStation to have failed. By default, it will try 5 times and wait 60 seconds. If this
is triggered by accident, reconfigure failover from the main TeraStation.
• Errors
Failover will occur if any of the following errors occur:
E12 (cooling failure), E14 (cannot mount RAID array), E16* (drive not found), E22* (cannot mount drive), E30*
(drive failure)
* When the drive is configured in JBOD.
Notes:
• Only use identical model and capacity TeraStations for failover. If the capacity of the main TeraStation is larger
than that of the backup TeraStation, an I33 replication error will occur.
• All drive bays of a TeraStation should be occupied if it will be used for failover. Failover will not work if a drive is
missing from any bay.
Before Configuring Failover
Use the same LAN ports for transferring data and configure both TeraStations with static IP addresses for the
purposes of failover.
When failover, the backup TeraStation will take over the hostname and IP address of the main TeraStation unless the
IP conflict is detected. If you want to assign different IP address to the backup TeraStation after failover, configure
the "service IP address". The service IP address will be a new address of the backup TeraStation when it takes over
operation from the TeraStation.
Using the Same LAN Port for Both Failover and Connecting to the Network
Using this setup, if the main TeraStation fails, the backup TeraStation will replace it completely. The backup
TeraStation will be updated over normal network traffic.

Using Different LAN Ports for Connecting to the Network and Failover
With this setup, the backup TeraStation and main TeraStation are connected by a second Ethernet cable connecting
their LAN 2 ports. Updating is done over this dedicated network path, so updates are quicker and don't interfere
with normal network traffic.

• LAN Port 1 for Alive Check and LAN Port 2 for Failover
Select the TeraStation labeled "(LAN1)" for "Registered Backup Device" and select "LAN 2" for "Backup LAN Port"
in Settings.
With this connection, the backup TeraStation will take over the IP address of the main TeraStation when the
network error occurred on the side of LAN port 1. However, the communication still available normally using
LAN port 2 so the backup TeraStation detects the IP conflict and the IP address of the main TeraStation will not
be taken over to the backup TeraStation.
• LAN Port 2 for Both Alive Check and Failover
Select the TeraStation labeled "(LAN2)" for "Registered Backup Device" and select "LAN 2" for "Backup LAN Port"
in Settings.
Usage Restrictions
Functional Restrictions
Failover is not available when any of the following functions are enabled:
106
Replication, sleep mode, encrypted drive volume, MySQL server, media cartridge, LVM volume, iSCSI volume, port
trunking, cloud storage, Dropbox Sync, surveillance server, hot spare, access restrictions by Active Directory or NT
domain
Setting Restrictions
The following functions will not be available while failover is enabled:
Initializing settings, changing the RAID settings, formatting drives, iSCSI volume, changing the backup TeraStation's
settings, turning the TeraStation on and off, updating the firmware
While failover is enabled, shutdown, power-on, and firmware update operations can be made available by
temporarily changing the TeraStation to maintenance mode. Maintenance mode can be enabled or disabled at
Backup - Failover in the main TeraStation's Settings. Click Maintenance mode to enable maintenance mode, or click
Cancel maintenance mode to disable maintenance mode.
To update the firmware while in maintenance mode, the main TeraStation can be updated from Settings, but the
backup TeraStation cannot. Download the firmware updater from the Buffalo website for the backup TeraStation
and try updating the firmware through it.
Non-Transferable Settings
The settings below are not copied from the main TeraStation to the backup TeraStation. Make a note of the original
settings so that they can be configured manually if failover errors.
Web server (including PHP), MySQL server, Direct Copy, WebAccess*, print server, UPS synchronization, antivirus**,
SNMP (when using SNMPv3)
* If the backup TeraStation took over the main TeraStation's IP address after failover, the WebAccess settings will not
be copied. Re-register your BuffaloNAS.com account for WebAccess. If the backup TeraStation kept its IP address, the
settings will be copied from the main TeraStation.
** The settings configured on the Trend Micro NAS Security settings page will not be copied to the backup
TeraStation. The settings configured on the main TeraStation's Settings page will be copied. Only if the antivirus is
activated on the TeraStation.
Using with UPS
Once failover is configured, you cannot set up a UPS for the backup TeraStation. Configure your UPS before
configuring failover. UPS recovery can be configured for both the main and backup TeraStations.
Configuring Failover
1 In Settings for the main TeraStation, click Backup.
2 Click to the right of "Failover".
3 Click Edit Failover Status.
107
4 Select a TeraStation to be the target backup device.
5 Enter the administrator password of the target backup device, then click Continue.
6 If the administrator password is correct, the backup TeraStation will beep. To accept the settings from the main
TeraStation, hold down the function button on the front of the backup TeraStation until it stops beeping.
7 The I51 message will display on the LCD panel and NAS Navigator2 for both TeraStations. Wait until
initialization finishes. Failover is configured after it finishes and the I51 message disappears.
8 To avoid a possible IP conflict after failover occurs, configuring a service IP address from the main TeraStation's
Settings is recommended.
Notes:
• If replication is configured for more than one folder, initialize the TeraStation before configuring failover.
• The main TeraStation cannot be used as the backup location for Time Machine.
• Do not use the same TeraStation for both failover and replication, or failover and Time Machine.
• If email notification is enabled and failover occurs, navigate to Management - Email Notification - Edit in the main
TeraStation's Settings and click OK.
• Ethernet frame size settings for main and backup TeraStations should be 1500 bytes. To change the Ethernet
frame size, navigate to Network - IP Address, click the LAN port, and change the Ethernet frame size to "1500"
bytes.
• Files whose filenames contain more than 80 alphanumeric characters will not be backed up.
• If the I33 error message appears on the LCD panel, navigate to Backup - Replication and click Resync.
• The RAID array on the backup TeraStation may be reconfigured and resynchronized as part of the failover
configuration process. This is expected behavior and not an error.
Replacing to the Backup TeraStation Manually
If "Switch to backup unit manually" is selected in the Advanced Settings tab on the main TeraStation's Settings, the
backup TeraStation will not replace the main TeraStation if the main TeraStation fails. To have the backup TeraStation
replace the main TeraStation, you can either:
• Log in to Settings for the backup TeraStation and click Set as Main Unit.
• Or, press and hold down the function button on the backup TeraStation.
Note: If the main TeraStation fails but both LAN ports' link on the backup TeraStation is up, the backup TeraStation
cannot replace to the main TeraStation from Settings. In such a case, use the function button instead.
108
Reconfiguring After Failover Occurs
When the backup TeraStation replaces the main TeraStation, the I49 message may appear on the backup
TeraStation's LCD display and in NAS Navigator2.
To configure failover again, follow the procedure below with the new TeraStation unit. The following procedure is an
example using the replaced backup TeraStation ("main TeraStation") and the new TeraStation ("backup TeraStation").
Note: This procedure will also work if failover occurs unexpectedly.
1 After failover occurs, log in to Settings for the main TeraStation.
Note: If you configured to sync with the UPS device connected to the failed TeraStation, the E10 error message
will be displayed on the main TeraStation. In such a case, follow the procedure below to configure the UPS
settings again.
(1) Disconnect the UPS cable from the failed TeraStation and connect it to the main TeraStation.
(2) In the main TeraStation's Settings, click Management.
(3) Click to the right of "UPS Sync".
(4) Click Edit.
(5) Select "Sync with UPS connected to this TeraStation" and reconfigure the desired UPS settings.

5 Click Force Failover to Stop to cancel the failover settings.
6 Shut down this main TeraStation.
7 Turn the backup TeraStation on.
8 Log in to Settings for the backup TeraStation, then rename the TeraStation's hostname and configure the IP
address so that it has a new static IP address.
9 Power on the main TeraStation. If you want to configure the UPS sync on the backup TeraStation, configure the
settings here. To sync with the UPS device connected to the main TeraStation, follow the procedure below.
(1) In the backup TeraStation's Settings, click Management.
(2) Click to the right of "UPS Sync".
(3) Click Edit.
(4) Select "Sync with UPS connected to another LinkStation or TeraStation on the same network" and
configure the main TeraStation as a sync source.
(5) Click OK when finished.
10 Reconfigure failover by referring to the "Configuring Failover" section above.
If you don't want to configure failover with the new TeraStation, cancel the failover settings and restart both
TeraStations. The I49 message will disappear.
Note: If you cancel the failover settings forcibly, attributes of the shared folders will become read-only. Change the
attribute settings to the desired option if necessary.

• If using after the network has been temporarily disconnected, click Remount.
• Do not copy more than 100,000 files at once to the WebAccess Remote target folder. If copying fails, try again
with fewer files.
119
• Be careful with existing files in the target folder, as files with the same name will be overwritten even if copied
files are older.
• If you copy a file to the WebAccess Remote source folder using Explorer or a backup process, the file will also
be copied sequentially to the WebAccess Remote target folder. This second copying process will start in the
background during the first copying process and will not be visible. If you shut down or restart the TeraStation
immediately after copying a file to the source folder, the file may not be copied to the target folder. Try copying
the file again if this occurs.
• If saving 1 TB or more files to or from the WebAccess Remote target folder, make sure there is enough free space
on the WebAccess Remote source TeraStation for temporary file caching. For example, when saving 1 TB of files to
the WebAccess Remote target folder, it is recommended to keep at least 2 TB of free space available.
FTP
By default, the TeraStation's shares are only accessible by users connected to the same network or router as the

• Port: 21
Accessing the TeraStation with an Anonymous User
To allow anonymous access to your FTP share, disable access restrictions. Configure your FTP client software with
the following settings for anonymous FTP access:
• Hostname: IP address of the TeraStation
• Username: Anonymous
• Password: Any character string
• Port: 21
Notes:
• If the TeraStation joins a domain, anonymous users cannot access it.
• Shared folders connected by FTP are available from the "/mnt" directory. The examples of default locations are:
120
/mnt/array1/share
/mnt/disk1/share
/mnt/usbdisk1
• If a file was created or copied by AFP, you may not be able to delete it using an FTP connection. If this occurs, use
an SMB or AFP connection instead to delete the file.
• For FTP connections, make sure that the total filename including directory path is 250 single-byte characters or
less.

correctly starting from step 4.
• Be careful with existing files in the destination folder, as files with the same name will be overwritten even if
copied files are older.
• If you copy a file to the remote folder using File Explorer or a backup process, the file will also be uploaded
sequentially to the cloud storage bucket. This second uploading process will start in the background during the
first copying process and will not be visible. If you shut down or restart the TeraStation immediately after copying
a file to the remote folder, the file may not be uploaded to the bucket. Try copying the file again if this occurs.
• If you encounter any upload or download errors, click Error Log. The log will display the filename and operation
during which the error occurred.
• If uploading fails, try copying the file again. If it still fails, click Reconnect or set the cloud storage switch to off and
on again, then restart the cloud storage service.
• If transferring or accessing 1 TB or more files from cloud storage, make sure there is enough free space on
the TeraStation for temporary file caching. For example, when uploading 1 TB of files to cloud storage, it is
recommended to keep at least 2 TB of free space available.

• After receiving the Wake-on-LAN packet, the TeraStation may take approximately five minutes to be ready to use.
• To use Wake-on-LAN, you'll need Wake-on-LAN software that sends magic packets. The TeraStation does not
include Wake-on-LAN software.
191
• The TeraStation does not support using Wake-on-LAN and port trunking at the same time. You may use either
feature, but not both at the same time.
• On the local network, Wake-on-LAN packets may be sent to port 2304 on either of the TeraStation's LAN ports. If
the TeraStation is connected to a Buffalo wireless router configured for remote access, then it may be turned on
from outside the local network (from the WAN side). To use this feature, connect the router to only LAN port 1 on
the TeraStation.
UPS (Uninterruptible Power Supply)
If a UPS (sold separately) is attached, the TeraStation can be automatically shut down to protect data in the event of
a power outage.
1 Plug the power cable of the UPS to a wall socket.

7 Click Edit.
8 Configure the desired settings, then OK.
192
Notes:
• If the TeraStation is connected directly to a UPS, select "Sync with UPS connected to this TeraStation". If a different
TeraStation is connected to the UPS, select "Sync with UPS connected to another LinkStation or TeraStation on
the same network". After making this selection, enter the IP address of the TeraStation that will be the sync source
into "Other LinkStation or TeraStation's IP Address".
• When the TeraStation is turned on after an automatic shutdown such as from a power outage or power supply
problem, verify that the power supply has been restored and a minute passed since the power supply was
restored. If the TeraStation is turned on while it is still running on the UPS and without the power supply restored,
automatic shutdown is not performed, even after the specified time has elapsed.
• If the power supply from the UPS to the TeraStation is stopped and restarted when UPS recovery is enabled, the
TeraStation is automatically restarted.
Port Trunking
Two Ethernet cables can be used to establish two separate communication routes, providing LAN port redundancy
and improving communication reliability. The use of two Ethernet cables enables access to the TeraStation even if
one of the cables is disconnected.
The port trunking modes that can be set in the TeraStation are shown below.
Trunking Mode Characteristics
Round-robin*Network packets are transmitted in sequential order from the first
available NIC slave through the last.
Active-backup Only one NIC slave in the bond is active. A different slave becomes
active if and only if the active slave fails.
XOR*
Transmits network packets based on [(source MAC address XOR'd
with destination MAC address) modulo NIC slave count]. This selects
the same NIC slave for each destination MAC address.
Broadcast Transmits network packets on all slave network interfaces.
Dynamic link aggregation
Creates aggregation groups that share the network speed and duplex
settings. Utilizes all slave network interfaces in the active aggregator
group according to the 802.3ad specification.
To use this mode, a separate intelligent switch that supports IEEE
802.3ad is required. Configure LACP in the switch first.
TLB The outgoing network packet traffic is distributed according to the
current load (relative to the speed) on each network interface slave.
* A separate intelligent switch that supports EtherChannel or other port trunking is required. Configure two LAN
ports on the switch for port trunking first.
Note: If the TeraStation is being used as an iSCSI hard drive, disable iSCSI before changing network settings such as
port trunking. Navigate to Drives - iSCSI in Settings and move the iSCSI switch to the "off" position temporarily.
1 Use an Ethernet cable to connect the hub LAN port and TeraStation LAN port 1.
Notes:
• Do not connect the second Ethernet cable to the TeraStation yet.
• If using an intelligent switch, configure the LAN ports on the switch first, before connecting to the
TeraStation.
2 In Settings, click Network.
193
3 Click to the right of "Port Trunking".
4 Choose a port trunking link.
5 Select the LAN port that will be used, select the port trunking mode, and click Accept.

Accessing from an NFS Client
Note: (US customers only) Buffalo's customer support will help configure the NFS settings on your TeraStation, and
will support VMware and Windows clients but will not provide support for configuring your Linux or other UNIX
clients. There are many types of UNIX and the procedure for configuring NFS with them will vary considerably.
For help configuring your NetWare, Linux, or other UNIX clients for NFS support, please consult each client's own
documentation and support.
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Choose the shared folder that will be accessible for the NFS client.
4 Click Edit.
5 Under "LAN Protocol Support", select the "NFS" checkbox and click OK.
Note the NFS path. It will be used later for accessing data from an NFS client.
6 Click Close.
7 Move the NFS switch to the position to enable NFS.
8 Click to the right of "NFS".
200
9 Click the Client Settings tab.
201
10 Click Add Client.
Note: To delete a client, select the checkboxes of the clients in the list and click Delete Client.
11 Enter the IP address and hostname of the NFS client, then click OK. You should add all NFS clients to access the
shared folder.
Notes:
• To restrict NFS access to a specific network or client, navigate to File Sharing - NFS - Services and click Edit. Enter
the address of the network. For example, if your local network subnet has a router at 192.168.1.1 and clients
with IP addresses in the range from 192.168.1.2 through 192.168.1.48 with subnet mask 255.255.255.0, then the
"Public Network Address" would be 192.168.1.0 and the "Public Subnet Mask" would be 255.255.255.0. This would
mean that only clients on this local network would be able to access the NFS share. If the default settings are used
202
(0.0.0.0 for both the public network address and the public subnet mask), then access to the NFS share will not be
restricted.
• To use shared folders set for NFS as drives on VMware ESX/ESXi, change the operation mode from "User Mode"
(default setting) to "Kernel Mode" on the screen navigating to Services - Edit.
• If you configure "Guest Permission" to "Forced" on the screen navigating to Services - Edit, user ID and group ID
should be 99 when the data is written from NFS clients; this is recommended for SMB or other protocols as well.
Use "Ignored" if the TeraStation only enables NFS connection.
NFS Mount Commands
Enter the mount command to access the shared folder from the NFS client. The mount command depends on your
operating system. The examples below assume that IP address of your TeraStation is 192.168.11.10, "/mnt/array1/
share" is the desired NFS path, and "/mnt/nas" or drive letter "z" is the mount point.
For Linux:
mount -t nfs 192.168.11.10:/mnt/array1/share /mnt/nas
For Windows Service for Unix 3.5:
mount 192.168.11.10:/mnt/array1/share z:
For Solaris 10:
mount -F nfs 192.168.11.10:/mnt/array1/share /mnt/nas
For macOS (NFS is working in kernel mode):
mount -t nfs -o resvport 192.168.11.10:/mnt/array1/share /mnt/nas
Encrypting Data Transmission
Encrypting Settings Data
All communication with Settings can use SSL encryption if you access the Settings page by changing "http://" to
"https://" in the browser address bar or click Secure Connection from the login window. Once you are logged in using
the HTTPS connection have disabled SSL encryption, click Normal Connection from the login window.
Encrypting FTP Transfer Data
Using SSL/TLS Encryption
You can encrypt passwords and files using SSL/TLS for secure FTP communication. First, open a shared folder's
settings and click Edit; under "LAN Protocol Support", select the "FTP" checkbox and click OK. Enable SSL security in
the setup screen for your FTP client. The procedure depends on the FTP client software.
Using SSH Encryption
You can encrypt passwords using SSH for secure FTP communication. First, open a shared folder's settings and
click Edit; under "LAN Protocol Support", select the "SFTP" checkbox and click OK. Also, you have to enable the SFTP
service by moving the SFTP switch to the "on" position on "File Sharing".
SSL Keys
SSL keys are used during setup screen operations and FTP communication. SSL (Secure Socket Layer) is a type of
encryption system called public key encryption. Generally, SSL is managed by the two files below.
203
server.crt (SSL Certificates)
The TeraStation sends the file to a computer, and the computer uses it to perform encryption. The TeraStation
receives the encrypted data and uses server.key (the private key) to decrypt the data.
In SSL, this key contains the server certificate, and depending on your computer environment, a check may be
performed to determine the trustworthiness of the certificate. The server certificate included in the TeraStation in
the default settings was created by Buffalo, and in some cases the message "There is a problem with this website's
security certificate" may be displayed in your browser or other software. Disregard this message and continue.
server.key (SSL Private Key)
This file is used as a pair with server.crt (server certificate). This is required for decrypting the data that was
encrypted by the server certificate, and this is normally not revealed.
Note: The passphrase for the private key must be removed before importing to the TeraStation.
Updating SSL Key Files
To update a server certificate and a private key for SSL, follow this procedure.
1 In Settings, click Management.
2 Click SSL.
3 Register "server.key" for "Secret Key" and "server.crt" for "Server Certificate (.crt)", then click Import.
Notes:
• Place the SSL key files (server.key, server.crt) directly below the C root drive. The SSL key files may not be able to
be updated if it is placed in folders or paths that contain multibyte characters.
• If Settings cannot be displayed after updating, initialize the TeraStation settings.

keep them as is.
224
6 Click OK.
Notes:
• The default gateway in the "Network Settings" field will only affect LAN port 1; the DNS server addresses will
affect both LAN ports 1 and 2. If you change the DNS server address on either IP address settings page, it will
affect the other LAN port as well.
• Do not set the IP address of the same segment for LAN port 1 and LAN port 2. This may cause unstable network
communication.
• The following IP addresses are reserved and should not be used. If you configure one of them by accident,
initialize all settings by referring to the "Restoring Factory Defaults" section in chapter 10.
Local loopback address: 127.0.0.1, 255.255.255.0
Network address: 0.0.0.0, 255.255.255.0
Broadcast address: 255.255.255.255, 255.255.255.0
The IP address range from 224.0.0.0 to 255.255.255.255
Boot Authentication
Boot authentication allows you to authenticate the TeraStation while it's booting, and also prevent the TeraStation
from being used in an unauthorized or unexpected manner, such as in cases of theft.
If authentication fails, the TeraStation will remain on, but all functions and services are stopped. Users will not be
able to log in to Settings to make changes or access any shares.
Note Before Use
• To use boot authentication, a Windows PC is necessary to serve as the authentication server.
• When activating boot authentication, the hard drives on the TeraStation will be formatted and all data on the
drives will be erased. Back up any important data to another device. Even though the data is deleted, the RAID
array will be kept as is.
• Assigning the TeraStation a fixed IP address is recommended for boot authentication.
• When boot authentication settings finish, export the configuration file for backup. Refer to the "Exporting
Managed TeraStations to a File" section in the Boot Authentication Tool help for the procedure.
• Boot authentication cannot be enabled if any of the following functions is enabled: drive encryption, LVM, iSCSI,
and failover. Conversely, these functions cannot be enabled while boot authentication is enabled.
Important Notice
This feature was developed with the intention of preventing critical data leakage by rendering the TeraStation
unusable in cases of misoperation or missing important setting files. Before configuring boot authentication, back
up the data on the TeraStation by referring to the "Backup" section in chapter 5 and create a system initialization
drive by referring to the "Creating an Initialization Drive" section above. With these preparations, a TeraStation that is
unusable may be initialized and reverted to a usable state.
If any of the situations below occur, the TeraStation will stop booting and become inaccessible.
• The TeraStation is unable to communicate with the authentication server due to the server crashing or it being
on another network.
• The TeraStation unit has been deleted from Boot Authentication Tool or the Boot Authentication Tool database
has been erased.
• Security level is configured to "High" and the wrong passcode is entered 3 times.
Setting Up the Authentication Server on a Windows PC
To set up the authentication server, follow the procedure below. The authentication server must be on the local
network or VPN.
225
Note: For proper operation, make sure that the TeraStation and the authentication server are on a network with only
one router. If there are two or more routers on the network, the authentication server may not acquire the correct
TeraStation status. For example, if the TeraStation's IP address has been changed, its status does not change to
"Warning".
1 Download the application for the authentication server, "Boot Authentication Tool", from the Buffalo website
and install it onto the Windows PC.
2 Register the specific port number that is used on the application as a firewall exception rule. Navigate to
Control Panel - System and Security - Windows Firewall on the authentication server.
