17
Chapter 3 Sharing Files
Adding a Shared Folder
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Click Create Folder.
18
4 Configure the desired settings, then click OK.
Notes:
• Names may contain up to 27 alphanumeric characters, hyphens (-), and underscores (_). Do not use a symbol
as the first character in a name.
• The description may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do
not use a space as the first character.
• You may create up to 400 shared folders.
19
• If the names of shared folders accessed via AFP and FTP connections contain multibyte characters, configure
the client language in Management - Name/Time/Language to match the characters. If the setting does not
match, the shared folder name will not be displayed correctly.
• The following characters are handled differently by Mac OS and Windows. Avoid using these characters when
sharing data between Mac OS and Windows:
• Windows does not support some characters that Mac OS and the TeraStation allow. If you create a filename
on a Mac with any of the following characters, it will not display correctly on a Windows computer. With
OS X 10.2 or later, you may have to connect to the TeraStation via AFP in order to display or copy any of the
following characters:
? [ ] / \ = + < > ; : " , | *
• Do not use any of the following words as the name of a shared folder. These words are reserved for internal
use by the TeraStation: info, spool, lost+found, global, printers, homes, lp, authtest, ram, msdfs_root, mt-
daapd, usbdisk# (where # is a number, for example: usbdisk1)
• Don't use the following unsupported characters in shared folder names, workgroup names, or filenames:
• File and folder names may contain up to 255 single-byte characters.
• Folder and workgroup names whose names contain non-Roman characters may not be displayed correctly.
• If shared folders are accessed from a Mac, information files for the Mac may be generated automatically. Do
not 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.
- 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.
20
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.
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 hard drives will have "Read-only" added to the shared folder
description.
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 instructions below.
1 In Settings, navigate to File Sharing - Folder Setup and choose a shared folder or a USB drive to configure
hidden shares.
2 Check "Hidden Share (SMB Only)" 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.
Adding Users
Note: The TeraStation can register a maximum 300 of users, which includes the default users "admin" and
"guest".
1 In Settings, click File Sharing.
2 Click to the right of "Users".
3 Click Create User.
21
4 Enter the desired settings, then click OK.
Notes:
• Usernames may contain up to 224 characters, including hyphens (-), underscores (_), periods (.), !, #, &, @, $, *,
^, and %. Do not use a symbol as the first character.
• 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.
• The description may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do
not use a space as the first character.
• Passwords may contain up to 20 alphanumeric characters and the following characters: - _ @ ! # $ % & ' ( ) * + ,
. / ; < > = ? " [ ] ^ { } | ~. Do not use a symbol other than an underscore (_) as the first character.
• 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 as a username: root, bin, daemon, sys, adm, tty, disk, lp, sync,
shutdown, halt, operator, nobody, mail, news, uucp, ftp, kmem, utmp, shadow, users, nogroup, all, none,
hdusers, admin, guest, man, www, sshd, administrator, ftpuser, apache, mysql, splx
Importing User Information
You can import users in File Sharing - Users by clicking Import CSV File.
22
Format for user data: Username (required), password (required), and user description (optional).
Examples:
username1,password1,comment1
username2,password2,comment2
username3,password3,comment3
Guidelines:
• Use commas (,) as separators. Do not put spaces before or after commas.
• 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: Importing users may take some time. During import, other operations in Settings may be much slower
than usual.
Adding Groups
1 In Settings, click File Sharing.
2 Click to the right of "Groups".
3 Click Add Group.
23
4 Enter the desired settings, then click OK.
Notes:
• Group names may contain up to 224 alphanumeric characters, hyphens (-), underscores (_), and periods (.).
Do not use a symbol other than an underscore (_) as the first character.
• Group descriptions may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces.
Do not use a symbol or space as the first character.
• 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 as a group name: root, bin, daemon, sys, adm, tty, disk, lp, sync,
shutdown, halt, operator, nobody, mail, news, uucp, ftp, kmem, utmp, shadow, users, nogroup, all, none,
hdusers, admin, guest, man, www, sshd, administrator, ftpuser, apache, mysql, splx
24
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.
• Shared folders with limited access can still be used as backup destinations.
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.
25
: Read and write access allowed : Read access allowed : Access prohibited
7 Click OK.
Notes:
• The example above shows access restriction by group. To restrict access by user, click the Local Users tab and
select user permissions.
• If both read-only and read & write permissions are given to a user, the user will have read-only access. The
most restrictive access always applies.
Active Directory
If an Active Directory environment, the TeraStation uses 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 multi-byte 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. 10,000
users and 10,000 groups can be downloaded from the domain controller but are not supported.
1 In Settings, click Network.
2 Click to the right of "Workgroup/Domain".
3 Click Edit.
26
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".
27
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 are more than 5 minutes difference 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 the TeraStation has joined a domain network, you cannot connect to it via FTP.
28
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.
10,000 users and 10,000 groups can be downloaded from the domain controller but are not supported.
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.
7 Enter settings and click OK.
29
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.
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 the TeraStation has joined a domain network, you cannot connect to it via FTP.
30
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.
4 Select "Workgroup" and click Next.
5 If a prompt appears, click Yes.
31
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 de-selected 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
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".
32
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.
• 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.
33
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 steps 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 Arrays
TeraStations support many types of RAID. The type of RAID arrays available for use depends on how many drives are
installed in your TeraStation.
TeraStation Default RAID Mode
TS-2RZH (12-drive models) RAID 6
TS-2RZS (4-drive models) RAID 5
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 in NAS Navigator2, 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 in NAS
Navigator2 will change from I46 or I47 to I18.
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 times 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.
35
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 times the capacity of the
smallest drive. For 8 drives, the total usable capacity is 3 times 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 disk 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 disk 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 steps below.
1 In Settings, click Drives.
2 Click to the right of "RAID".
36
3 Click the array to delete.
4 Click Delete RAID Array.
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".
37
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.
9 Step through the wizard to create the array.
Note: After changing the RAID mode, create a shared folder.
38
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, RAID 6,
or RAID 61 array.
Note: 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.
1 In Settings, click Drives.
2 Click to the right of "RAID".
3 Choose a RAID array.
4 Click Set as a hot spare.
5 Step through the wizard.
6 When the "Confirm Operation" screen opens, enter the confirmation number and click OK.
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 steps 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.
39
(6) Click the drive that was previously configured as a hot spare, then click Recover RAID Array.
This will rebuild the RAID array.
• After the hot-spare drive replaces a failed drive and the RAID array finishes rebuilding, the hot-spare drive
status may still show "Hot Spare / Dismounted / Plugged". Check the drive status LED. If it has changed from
red to blue, the RAID array has finished rebuilding and is ready for use. This bug will be fixed in a future
firmware update.
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
Hard drives that aren't in a RAID array show "Normal". 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.
2 Click to the right of "RAID".
3 Choose a RAID array.
4 Set the RAID mode to "RAID 1".
40
5 Check "Add a disk to RAID array with RMM. Your data will be preserved.".
6 Select the drive whose data will be saved from the drop-down menu.
7 Select the drive to add to the RAID array.
8 Click Create RAID Array.
9 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
Adding a Drive to an Existing RAID Array
You can add a drive to a RAID 1, RAID 5, or RAID 6 array. Drives that can be added to the RAID array show "Normal".
Notes:
• Each drive must have the same capacity.
• 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".
41
3 Choose a RAID array.
4 Select the drive to add to the RAID array.
5 Click Create RAID Array.
6 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
Changing the RAID Mode While Adding a Drive
Select the drive you want to add to the RAID array and choose the mode for the array. Enter the "Confirm Operation"
number and click OK.
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.
42
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.
5 Select when to run the scan and click OK.
Notes:
• Check "Immediately" to run a RAID scan immediately.
• To stop a RAID scan, click Cancel RAID Scan.
• The "1st week" of the month is days 1–7 of the month. The "2nd week" is days 8–14 of the month, etc. If you
select one of these schedules, be sure to also select the day of the week for the scan to run.
• Normally the I15 message or code is notified through NAS Navigator2, Settings, or the error LED; however,
it may not be displayed if your TeraStation's firmware version is 2.30. RAID scanning will start correctly when
the scheduled time passes without the notification.
Adding an External Hard Drive
Connecting an External Drive
Your TeraStation includes USB ports, 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" under the TeraStation in "Network", where "X" is the USB
port where the hard drive is connected.
43
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.
Notes:
• Backup data from Mac OS 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.
• When external hard drives are connected to the USB port, they are recognized as shared folders with names
of the form "usbdisk x". Depending on which USB port they are connected to, they will have the following
settings by default:
USB ports 1 to 4: Trashbox and backup are enabled.
USB ports 5 and 6: Trashbox and backup are disabled.
Dismounting Drives
If the TeraStation is powered on, dismount drives (internal and external) before unplugging them. You may
dismount any drive from Settings. If the TeraStation is off, then all drives are already dismounted and may be
unplugged safely.
1 In Settings, click Drives.
2 Click Drives to dismount an internal drive or USB Drives to dismount an external drive.
44
3 Select the drive to dismount and click Dismount Disk.
4 When the following message is displayed, it is safe to unplug the drive.
Note: To remount the drive, unplug it and then plug it back in.
Checking Drives
A disk check tests the data on a drive in the TeraStation or connected via USB for integrity. Errors are fixed
automatically. With large drives, a disk check may run for many hours. Shared folders cannot be accessed during
a disk check. Do not turn off the TeraStation until the disk check is finished. Use the procedure below to run a disk
check.
1 In Settings, click Drives.
2 Select Drives to check an internal drive or USB Drives to check an external drive.
45
3 Select the drive to test, then click Check Disk.
4 Click Check. You have the option of deleting information files from Mac OS during the check if desired.
S.M.A.R.T.
S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) monitors hard 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 steps 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".
46
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
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.
47
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 "Erase 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.
3 Select the drive to format, then click Format Disk.
48
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 of your drive, the format may take several minutes or several hours to complete. The I20
message will be displayed in NAS Navigator2 until the format is complete.
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. For many drives, this
option will be enabled automatically during format.
49
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 unencrypt a drive or array, uncheck "Encryption" 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, check "Media Cartridge" during formatting. To return it to its original state,
uncheck "Media Cartridge" and reformat the drive.
Note: Format the drive with encryption disabled. If you format the drive as a media cartridge with encryption
enabled, you cannot use that drive in another TeraStation.
Media cartridges do not support:
• RAID arrays
• LVM volumes
• Access restrictions
• Direct connection to a Windows computer
50
Erase Data on the TeraStation Completely
Under some circumstances, data from formatted drives can be recovered. The disk 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. All data on the drives is completely erased.
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, NAS Navigator2 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. When the erase finishes, the TeraStation will shut down.
Disk Quotas
You can set a disk quota to limit drive space for each user or group. You can also set an threshold. If the drive space
exceeds the set threshold, an email notification will be sent. To configure email notifications for disk 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.
• If both user and group quotas are configured for a user, the most restrictive quota will always apply.
51
Quotas for Users
Follow this procedure to limit the shared folder disk space available for a user.
1 In Settings, click File Sharing.
2 Click to the right of "Users".
3 Select the user whose space will be limited.
4 Enable quotas, choose the maximum space the user will be allowed to use, and click OK.
5 Click OK.

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.
55
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 fixed 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.
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.
Creating a iSCSI Volume
To use the TeraStation as an iSCSI hard drive, create a volume first. Configure the TeraStation as described below.
Notes:
• If the LVM settings are changed, all data on the volume will be erased. Before changing any settings, back up
any important data.
• Up to 32 iSCSI and LVM volumes are supported. Exceeding this volume amount may cause irreparable
damage to the unit.
1 In Settings, click Drives.
Note: Steps 2–6 below describe the procedure to enable LVM for specifying a volume size or changing it later.
LVM does not need to be enabled for a drive 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 that will be used for
iSCSI.
To use whole drive or array as an iSCSI hard drive, skip to step 7.
2 Click to the right of "LVM".
56
3 Select the drive or array where the volume will be created and click Enable LVM on Volume.
4 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
5 Click OK.
6 Click Close.
Note: 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.
7 Move the iSCSI switch to the position to enable iSCSI.
57
8 Click to the right of "iSCSI".
9 Click Create Volume.
10 Enter a volume name, volume description, volume, and size (if you enabled LVM), then click OK.
The volume size that you specify here can be changed later. To change the volume size, refer to the "Expanding
Volume Sizes" section below.
11 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
12 Click OK, then Close.
Creating an iSCSI volume is finished.
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
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 fixed IP address for
the TeraStation is recommended.
Connecting Volumes
To connect a volume using Microsoft iSCSI Initiator from a Windows computer, follow the procedure below.
Note: Do not shut down the TeraStation while connecting to an iSCSI volume. It may cause unexpected data
erasure. Make sure all connections are disconnected before shutdown.
1 In Windows, navigate to Control Panel - Administrative Tools - iSCSI Initiator.
58
2 Enter the IP address of the TeraStation into the "Target" field and click Quick Connect.
3 Confirm if the connection is established and click Done.
Connecting a volume is finished.
If using the connected volume for the first time, the volume should be formatted to be used as a local drive. Follow
the procedure below for formatting.
1 In Windows, navigate to Control Panel - Administrative Tools - Computer Management.
2 Click Disk Management.
When the "Initialize Disk" screen is displayed, click OK without changing any settings.
3 Right-click the disk volume that shows the status "Unallocated" and click New Simple Volume from the
displayed menu. Follow the screen to finish formatting.
Formatting a volume is finished. When the formatting process is completed, the drive will be visible as an icon in
Computer or My Computer and can be used as a normal drive on the computer.
Disconnecting a Volume
1 In Windows, navigate to Control Panel - Administrative Tools - iSCSI Initiator.
The status of the connecting volume will be displayed as "Connected" under "Discovered targets".
59
2 Select a volume to disconnect and click Disconnect.
3 Click Yes.
4 When the volume status is displayed as "Inactive", the disconnection was carried out properly.
Disconnecting a volume is finished.
Using with Multiple Computers
If the TeraStation is divided into multiple volumes (or drives), it can be used with multiple computers. However,
multiple computers cannot be accessed from one volume (or one drive) at the same time.
Checking Whether iSCSI Volume is Connected
To check whether an iSCSI volume is connected, navigate to Drives - iSCSI. Current volumes will be listed. If
"Connected" is displayed under "Connection", the volume is currently connected from the client.
Configuring Access Restrictions
A CHAP name and secret can be configured for the entire iSCSI volume or each existing volume. Access restrictions
can be configured so that entering a target CHAP name and secret is required for each connection.
The TeraStation can perform mutual authentication (two-way authentication). Dual passwords ensure that only
authorized client computers can access the volume on the TeraStation.
Follow the procedure below to enable access restrictions.
Configuring Access Restrictions for the Entire TeraStation
1 In Settings, click Drives.
2 Click to the right of "iSCSI".
3 Click the Security tab.

Hard Drive Replacement
Hard drives in the TeraStation show a blue status LED during normal operation. If a drive fails, its error LED will glow
red. A failed drive whose status LED is extinguished may be hot-swapped.
Notes:
• Do not unplug a drive whose status LED is blue. 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, only use a Buffalo OP-HDZS series or OP-HDZH series drive of the same size (or
larger). If 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.
• Do not change the order of the hard drives in the TeraStation. For example, pulling out drive 1 and replacing
it with drive 2 may cause data to be corrupted or lost.
• If a new drive is not recognized, click Rediscover Disk in Settings.
65
• If two drives fail at the same time, replace and resync them one at a time.
Using JBOD or a Redundant RAID Mode Other Than RAID 0 with
Auto-Shutdown Disabled
This section describes replacing a drive with the TeraStation on.
1 The failed drive's status LED will be extinguished. Push its unlock button and swing the lock mechanism out.
2 Pull out the drive cartridge and remove it from the TeraStation.
3 Insert the new drive into the empty slot. Slide the drive in with the locking mechanism open.
4 Swing the lock back down until it clicks into place.
12
5 When the replacement hard drive is recognized, the status LED will glow blue.
6
66
For a redundant RAID mode such as RAID 1, 5, or 6:
If auto RAID rebuild is enabled, the TeraStation will start rebuilding the RAID array automatically. If not,
navigate to Drives - RAID in Settings and rebuild the RAID array.
For JBOD:
Navigate to Drives - Drives in Settings and click Format Disk to format the new drive.
Using a Redundant RAID Mode Other Than RAID 1 with Auto-
Shutdown Enabled
This section describes the process of replacing a drive while the TeraStation is off.
While the TeraStation is off, there is no way to know which hard drive is malfunctioning. Make sure you have
configured email notification so that if a drive fails, you will be notified of the drive number.
1 Push the unlock button of the failed hard drive and swing the lock mechanism out.
2 Pull out the drive cartridge and remove it from the TeraStation.
3 Insert the new hard drive into the empty slot. Slide the drive in with the locking mechanism open. Swing the
lock back down until it clicks into place.
4 Press the power button on the TeraStation.
5 When the replacement hard drive is recognized, the status LED will glow blue.
6 If auto RAID rebuild is enabled, the TeraStation will start rebuilding the RAID array automatically. If not,
navigate to Drives - RAID in Settings and rebuild the RAID array.
Using RAID 0
Drives in a RAID 0 array do not automatically turn off in the event of a malfunction. Before replacing the failed
drive, either dismount the drive from Settings, or shut down the TeraStation. This section describes the process of
replacing a drive with the TeraStation on.
1 In Settings, navigate to Drives - Drives.
2 Select the hard drive with the red error LED and click Dismount Disk.
3 The status LED will change from steady blue to off.
4 Unlock the failed drive by pushing the unlock button and swinging the lock mechanism out.
5 Pull out the hard drive cartridge and remove it from the TeraStation.
6 Insert the new hard drive (sold separately) into the empty slot. Slide the drive in with the locking mechanism
open. Swing the lock back down until it clicks into place.
7 When the replacement drive is recognized, the status LED will glow blue and the message "Set From Web I32
New Diskx ready" will be displayed in NAS Navigator2.
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.
If a hard drive malfunctions in RAID 0, all data on the RAID array will be lost. All of the settings for the shared
folders (such as access restrictions) are erased after replacing a drive from a RAID 0 array. Create a shared folder
before use.
67
Drive Replacement with a Hot Spare Configured
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 disk 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 The failed drive's status LED will be glowing red. Push its unlock button and swing the lock mechanism out.
2 Pull out the drive cartridge and remove it from the TeraStation.
3 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.
4 When the replacement drive is recognized, the status LED will glow blue. 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.
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.
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 Other Than RAID 0
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.
68
Chapter 5 Backup
Back 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
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", check "Backup" and click OK.
Note: To configure a password, enter it into the "Remote Backup Password" field. Leave this field blank if you
don't want a password. If the target device is configured with a backup password, you can easily find the backup
target folder during configuration of the backup job by searching for the password.
Backing up to a LinkStation or TeraStation on another network when connected by
a VPN
You can back up to a LinkStation or TeraStation 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 target LinkStation or TeraStation.
1 In Settings, click Backup.
69
2 Click to the right of "Backup".
3 Click List of LinkStations and TeraStations.
70
4 Click Add under "Off-subnet Devices", enter the IP address or hostname of the target LinkStation or TeraStation,
and click Close.
If your setup meets the requirements below, you don't have to configure these settings:
• The source and target TeraStations are on the same network.
• No backup password is set for the target TeraStation.
• No TeraStation from outside the subnet or connected by a VPN, is used.
Notes:
• To back up data between LinkStations or TeraStations 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 hostname by a fully qualified domain name (FQDN).
• Windows-based TeraStations with multibyte characters in the hostname may not be detected as a backup
target, and folders in these devices cannot be used as backup target folders.
Configuring a Backup Job
1 In Settings, click Backup.
2 Click to the right of "Backup".
71
3 Click Create New Job.
Note: Up to 8 backup jobs can be configured.
4 Select backup settings such as date and time to run.
The following types of backup jobs may be selected:
72
Type Files included
Normal backup All files in the source will be backed up to the destination.
Overwrite (incremental)
The first backup job will run 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 will run 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.
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 (such as 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 target 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. 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.
5 Click Add.
6 Click Browse under "Backup Source Folder Name".
7 Select the shared folder that will be the backup source, then click OK.
8 Click Browse under "Backup Target Folder Name".
73
9 Select the backup target and click OK.
10 Click OK. Jobs added to "Backup List" are displayed.
11 Click Close.
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 steps below.
Notes:
• For best results, use static IP addresses for both replication TeraStations (source and target).
• Replication source data is copied to the replication target 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".
74
3 Choose the folder to set as a replication destination.
4 Click Edit.
5 Under "LAN Protocol Support", check "Backup" and click OK.
Note: Do not configure a backup password for the shared folders. Folders with a backup password set cannot be
selected as replication targets.
Configuring a Replication Task
1 In Settings, click Backup.
2 Click to the right of "Replication".
3 Click Edit.
75
4 Click Add.
5 Click Browse under "Replication Source".
6 Select the shared folder that will be the replication source, then click OK.
7 Click Browse under "Replication Target".
76
8 Select the shared folder that will be the replication target, then click OK.
9 Click OK.
10 Click Yes.
Notes:
• During setup, you may choose to encrypt and/or compress replication data. Encrypted data will be
transferred securely on the network. Compressed data will ease network loading and is recommended for
slow or heavily loaded network connections. Either will increase the CPU load on the source TeraStation.
Encrypted and compressed data will be unencrypted and decompressed on the target TeraStation.
• For best results, add replication jobs one at a time. Multiple replication tasks may take some time to
complete.
• 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 subfolders as the replication source. Folders whose names contain more than 80 alphanumeric
characters cannot be selected.
• If an I33 error appears on NAS Navigator2, navigate to Backup - Replication and click Resync.
• Do not use the same TeraStation for both failover and replication, or replication and Time Machine.
• Do not configure replication from one source folder to multiple target 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 target folder.
77
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.
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)
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.
Usage Restrictions
Functional Restrictions
Failover is not available when any of the following functions are enabled:
Replication, sleep mode, encrypted disk volume, MySQL server, media cartridge, LVM volume, iSCSI volume, port
trunking, Amazon S3, surveillance server, hot spare, access restrictions by Active Directory or NT domain
The following operations will not be available while failover is enabled:
Initializing settings, changing the RAID settings, formatting drives, iSCSI volume, changing the backup unit's settings
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 unit'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.
78
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
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. However, the UPS
settings of the main TeraStation will not be copied to the backup TeraStation.
If the backup TeraStation is configured to sync with the UPS connected to the main TeraStation, and the main
TeraStation becomes unavailable, the backup TeraStation will not be able to detect a power outage. In this case,
move the UPS cable from the main TeraStation to the backup TeraStation and reconfigure the UPS link settings.
Configuring Failover
There are two ways to set up a connection for failover. Regardless of configuration, during failover the backup
TeraStation will assume the name and IP address of the main TeraStation, unless a "service IP address" is set for the
backup TeraStation unit during failover configuration. The "service IP address" will be the new address of the backup
TeraStation when it takes over operation from the main TeraStation.
It is recommended that both TeraStations are configured with static IP addresses for the purposes of failover.
Otherwise, if the main TeraStation becomes inaccessible and later comes back online, an IP conflict may occur.
Using LAN port 1 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.
79
Using LAN port 1 for connecting to the network and LAN port 2 for failover
With the second 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.
Configuration
1 In Settings for the main TeraStation, click Backup.
2 Click to the right of "Failover".
3 Click Edit Failover Status.
4 Select a TeraStation to be the target backup device.
5 Enter the administrator password of the target backup device, then click Continue.
80
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 in 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 Edit, 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 in NAS Navigator2, navigate to Backup - Replication and click Resync.
• If failover occurs unexpectedly due to issues such as network problems, even if neither TeraStation has failed,
log in to both the main and backup TeraStations' Settings interface, reset the failover settings, and configure
it again.
• 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.
Switching to the Backup Unit Manually
If "Switch to backup unit manually" is selected in 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.
Reconfiguring Failover if No Service IP Address was Set
When the backup TeraStation replaces the main TeraStation, the I49 message may appear in NAS Navigator2.
If you did not set a service IP address and failover occurs, it is recommended that you manually reconfigure failover
for both TeraStation units, assuming the original main TeraStation is still viable. This should be done as soon as
possible after failover occurs in case the original main TeraStation comes online, which might create an IP conflict.
If the original main TeraStation is no longer viable but you have a replacement ready, refer to the "Configuring
Failover" section above.
1 After failover occurs, log in to Settings for the current main TeraStation.
2 Click to the right of "Failover".
3 Force failover to stop.
4 Log out of Settings and shut down this TeraStation.
5 If the original main TeraStation is fully functional, connect it to the network and powered it on.
81
6 Rename the unit and configure the IP address so that it has a new static IP address.
7 Power on the current main TeraStation. With the two units on the same network, reconfigure failover with the
units' former roles reversed, referring the "Configuring Failover" section above.
Backing Up Your Mac with Time Machine
Time Machine is a backup program included with OS X 10.5 or later. Configure your TeraStation as shown to use
Time Machine.
1 In Settings, click File Sharing.
2 Move the AFP switch to the position to enable AFP.
3 Click to the right of "Folder Setup".
4 Choose a shared folder as your backup destination for Time Machine.
5 Click Edit.
6 Under "LAN Protocol Support", check "AFP (Mac)" and click OK.
7 Click OK.
8 Click Close.
9 Click Backup.
10 Click to the right of "Time Machine".
11 Click Edit.
82
12 Click Browse.
13 Select the shared folder that you set in the previous step, then click OK.
14 Click OK.
15 Click OK.
16 Move the Time Machine switch to the position to enable Time Machine.

19 Click Select Backup Disk.
20 Select the TeraStation, then click Use Disk.
85
21 Enter a username and password with the rights to access the shared folder of the TeraStation, then click
Connect.
Note: If access restrictions are not configured on the target share, log in with the administrator account. The
default username and password for the administrator account are "admin" and "password". If access restrictions
are configured, log in with an account with write privileges.
22 Time Machine will count down from 120 seconds, and the backup will begin.
Note: Because the backup operation is performed in the background, Mac OS operations and shutdown can be
performed normally. If recovering data or setting items excluded from the backup, refer to the Mac OS help.
86
Chapter 6 Remote Access
WebAccess
WebAccess is a software program for accessing the files in the shared folder of your TeraStation from your computer
or mobile devices through the Internet. Be careful when configuring WebAccess. Certain settings can make the
files in the shared folder available to anyone on the Internet, without any access restrictions.
1 In Settings, click File Sharing.
2 Click to the right of "WebAccess".
3 Click Edit.
87
4 Configure the desired settings, then click OK.
• To use SSL encryption for more secure data transfers, enable "HTTPS/SSL Encryption".
• You may use the default BuffaloNAS.com registration, or disable to use a different DNS server.
• Choose a "BuffaloNAS.com Name" and "BuffaloNAS.com Key" for your WebAccess account. Names and keys
may use 3 to 20 alphanumeric characters, underscores (_), and hyphens (-).
• If "Exclusive Session" is enabled, users cannot log multiple computers into WebAccess. Only the last login
will be active.
• Enter a time in minutes (1 to 120, or "Unlimited") before inactive users are logged out of WebAccess.
5 Click OK.
6 Move the WebAccess switch to the position to enable WebAccess.
7 Click to the right of "Folder Setup".
8 Select a shared folder to publish.
Notes:
• For best results, create a new dedicated share for WebAccess.
• When accessing shared folders through WebAccess from a remote location, a username and password may
be required for certain operations. For best results, create a user account with permissions on the WebAccess
share before using WebAccess.
9 Click Edit.
10 Under "LAN Protocol Support", check "WebAccess" and click OK.
88
Notes:
• The following levels of security are available:
"Allow Anonymous" - Anyone can access (view) shared folders.
"Allow All Groups and Users" - All groups and users registered on the LinkStation or TeraStation can use
WebAccess.
"Use Inherited Folder Permissions" - Users and groups have the same access permissions with WebAccess that
they do locally. If access restrictions are not set for the shared folder, then this option will not be shown.
• When a user or group can access a folder through WebAccess depends on a combination of WebAccess
settings and the shared folder's settings.

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". In this case, both TeraStations should connect to the same UPS. Then, enter
the IP address of the TeraStation that will be the sync source in "Other LinkStation or TeraStation's IP Address".
• When the TeraStation is restarted after an automatic shutdown (such as from a power outage or power
supply problem), verify that the power supply has been 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 you enable both "Shut down UPS after TeraStation shuts down" and "Wake up TeraStation after AC
recovery", the UPS will shut down after the TeraStation shut down due to the power failure, and the
TeraStation will boot automatically when power is recovered.

Accessing from an NFS Client
Note: (US purchasers only) Buffalo's customer support will help configure the NFS settings on your TeraStation,
and will support VMware, Citrix, and Windows clients but will not provide support for configuring your Linux or
other UNIX clients. There are many types of UNIX and the procedures 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 to the NFS client.
4 Click Edit.
5 Under "LAN Protocol Support", check "NFS" 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".
9 Click Client Settings.
10 Click Add Client.
11 Enter the IP address and hostname of the NFS client, then click OK.
Note: To delete a client, check the hostname and click Delete Client.
12 Click Close.
13 Enter the mount command to access the shared folder from the NFS client.
158
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 OS X (NFS is working in kernel mode):
mount -t nfs -o resvport 192.168.11.10:/mnt/array1/share /mnt/nas
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 (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 NFS folders with VMware ESX/ESXi or Citrix, navigate to Services - Edit and change the operation mode
from "User Mode" to "Kernel Mode".
• Async is the default for NFS rules. Sync is available only when the device is in kernel mode.
159
• To restrict access to a NFS share for specific clients, navigate to File Sharing - NFS - NFS Rules and click Add
Rule. Choose the folder to restrict access to, and enter the clients that will have restricted access in the "Hosts"
field. Clients may be entered by hostname, IP address, or IP address range. Wildcards are supported. Separate
multiple entries with commas. You may assign read-only or read & write access to the listed clients. Rules
override settings made from the Services tab.
Encrypting Data Transmission
Encrypting Settings Data
All communication with Settings can use SSL encryption if you access settings through https://.
Encrypting FTP Transfer Data
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", check "FTP" and click OK. Enable SSL security in the setup
screen for your FTP client. The procedure depends on the FTP client software.
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.
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 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.
Updating SSL Key
To update a server certificate and a private key for SSL, follow this procedure.
1 Navigate to Management - SSL.
2 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 may not be able to
be updated if it is placed in folders or paths that contain multi-byte characters.
• Use the provided password for the SSL key.
• If Settings cannot be displayed after updating, initialize the TeraStation settings.
• Updating the firmware initializes an SSL key.

Note: The internal clocks of the TeraStation and other devices on your network may run at slightly different
speeds. Over a long period of time your network devices may show somewhat different times, which can cause
network problems. If clocks on your network vary by more than 5 minutes it may cause unexpected behavior.
For best results, keep all clocks on the network set to the same time by adjusting them regularly, or use an NTP
server to correct them all automatically.
171
6 Click the Language tab. Select the language to be used and click OK.
Note: This tab changes the language used by the TeraStation for email notifications, DLNA, and other functions.
To change the language displayed in Settings, open Settings and click Language in the menu bar. Choose your

Notes:
• To use jumbo frames, your computer's NICs and all switches, hubs, and routers on the network need to
support jumbo frames. If any device on the network does not support jumbo frames, use standard frames
(1500 bytes) instead.
• Frame sizes smaller than 1500 bytes are not supported.
• The maximum frame size depends on the LAN port: LAN ports 1–4 (10/100 ports) have a maximum frame size
of 9216 bytes while LAN ports 5 and 6 (10 Gb expansion ports) have a maximum frame size of 9000 bytes.
• Frame sizes are used as shown. Some systems subtract 18 bytes from the entered value, but the TS7000 does
not.
• If the TeraStation is being used as an iSCSI hard drive, to change the settings, navigate to Drives - iSCSI and
move the iSCSI switch to the position temporarily before changing network settings.
Changing the IP Address
Normally, the TeraStation's IP address is set automatically from a DHCP server on your network. If you prefer, you can
set it manually. An easy way to do this is to change it from NAS Navigator2 running on a computer connected to the
same router (subnet) as the TeraStation. The procedure to change the IP address in Settings is below.
Note: If the TeraStation is being used as an iSCSI hard drive, to change the settings, navigate to Drives - iSCSI in
Settings and move the iSCSI switch to the temporarily before changing network settings.
174
1 In Settings, click Network.
2 Click to the right of "IP Address".
3 Click on the LAN port whose IP address you want to configure (normally LAN port 1) and click Edit.
4 Disable "DHCP" and enter the desired network address settings, then click OK.
Notes:
• From the IP address list, other settings are available at the bottom left of the window. Click Change to modify
the gateway and Wake-on-LAN settings. Click Allowed Protocols for Each Port to restrict by LAN port which
175
protocols network connections can use. Click Port Trunking to combine ports in trunked combinations. See
the next section for more on port trunking.
• To use a different default gateway, click Change and select the LAN port to modify. This might be useful if you
want the default gateway to be assigned by another port besides the default LAN port 1.
• Do not configure more than one LAN port with the same IP address. 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
Port Trunking
The multiple Ethernet ports on the TeraStation can provide redundancy and reliability. Several port trunking modes
are available:
Note: If you will use port trunking with ports on expansion cards, only "Dynamic link aggregation" will be
available for the port trunking mode.
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.
TLB The outgoing network packets traffic is distributed according to the
current load (relative to the speed) on each network interface slave.
ALB Includes both balance-tlb and rlb by ARP negotiation.
*A separate intelligent switch that supports EtherChannel or other port trunking is required. Configure the LAN
ports on the switch for port trunking first.
**A separate intelligent switch that supports IEEE 802.3ad is required. Configure LACP in the switch first.
Configuring Port Trunking
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 position temporarily.
1 Use an Ethernet cable to connect the hub LAN port and TeraStation LAN port.
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.
176
2 In Settings, click Network.
3 Click to the right of "Port Trunking".
4 Choose which ports will be trunked.
5 Select the port trunking mode. Some modes allow the hash policy to be configured as well. Click OK.
6 Click Save.
177
7 Connect the hub's LAN port and TeraStation's LAN port using the second LAN cable. If you are using an
intelligent switch, connect to the LAN port that was previously configured for port trunking.
8 Restart the TeraStation before use.
