the shared folder name will not be displayed correctly.
• The following characters are handled differently by macOS and Windows. Avoid using these characters when
sharing data between macOS and Windows:
―〜∥−￠￡￢
• Windows does not support some characters that macOS 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. You may have to
connect to the TeraStation via AFP in order to display or copy any of the following characters:
? [ ] / \ = + < > ; : " , | *
28
• Do not use any of the following words for the name of a shared folder as these words are reserved for internal
use by the TeraStation: authtest, global, homes, info, lost+found, lp, msdfs_root, mt-daapd, printers, ram, spool,
usbdisk x (where "x" is a number, for example: usbdisk1)
• Don't use the following unsupported characters in shared folder names, workgroup names, or filenames:
①②③④⑤⑥⑦⑧⑨⑩⑪⑫⑬⑭⑮⑯⑰⑱⑲⑳ⅠⅡⅢⅣⅤⅥⅦⅧⅨⅩ

• 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.
• 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.
• If the Ethernet cable is disconnected from the LAN port during file copying, even if the cable is not in use, the
copy operation will abort. Do not disconnect or reconnect the Ethernet cable to the LAN port during file copying.
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 "Keep when original file is deleted" for "Mac OS Temp Files" 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 at Attribute
on the "Option 2" tab. Read-only shares and HFS Plus-formatted USB drives will have "(Read Only)" added to
comments in Explorer.
29
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 Click the Option 2 tab and select the "Hidden share (SMB only)" checkbox, then click OK.
Notes:
• If protocols other than "SMB" or "Backup" under "LAN Protocol Support" on the "Basic" tab 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.

30
3 Click Create User.
31
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 multibyte or 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 a name already in use as a group; do not use any of the following words as a username as these
words are reserved for internal use by the TeraStation: _lldpd, admin, apache, avahi, avahi-autoipd, backup, bin,
daemon, ftp, games, gnats, guest, halt, irc, libuuid, list, lp, mail, man, messagebus, mysql, news, nobody, ntp,

Configuring Access Restrictions for Shared Folders
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 the Access Restrictions tab.
36
5 Enable "Access Restrictions for Shared Folders".
6 Select the level of access for the user or group you added.
: 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 10,000 users and groups.
1 In Settings, click Network.
37
2 Click to the right of "Workgroup/Domain".
3 Click Edit.
4 Select "Active Directory", then click Next.
5 Click Yes.
6 Enter the domain controller information and click Search. The domain controller on the same network will be
detected and required settings will be entered into each box automatically. Or, enter the settings manually.
7 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, select
"Configure domain controller as an NTP server" if the domain controller can function as the NTP server.
8 Click OK.
38
9 Click to the right of "Folder Setup".
10 Click a shared folder that you want to set access restrictions for.
11 Click the Access Restrictions tab.
12 Enable "Access Restrictions for Shared Folders".
13 Select the level of access for the user or group.
: Read and write access allowed : Read access allowed : Access prohibited
14 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.
• 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.
39
• 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.
• 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.
• If you allow read and write or read-only access for most users, group access restrictions are recommended.
Configuring Access Restrictions for Subfolders
You may restrict access to subfolders in shared folders by configuring the access restrictions from your computer
using Windows Explorer.
Note: Depending on the environment, the function may not work properly even if it's enabled. We recommend
verifying the functionality before using.
Enabling Subfolders' Access Restrictions
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.
40
4 Clear all checkboxes for "LAN Protocol Support" other than "SMB (Windows/Mac)", "Backup", and "NFS".
5 Click the Option 2 tab.
6 Enable "Access Restrictions for Subfolders".
Note: If "Hide Non-Access Permitted Files and Folders" is enabled, non-access permitted sub-files and folders
will not be displayed in shared folders.
7 Click OK.
Enabling subfolders' access restrictions finished. Next, configure access restrictions for each user or group for
subfolders from Windows Explorer.
You may configure domain users and groups. You should have the TeraStation join your Active Directory domain
before configuring the subfolders' access restrictions.
Notes:
• If enabling subfolders' access restrictions for a USB drive, the drive should be formatted by XFS or ext3.
• The UID and GID of domain accounts should be updated before using the subfolders' access restrictions if the
TeraStation joined the AD network while running firmware version 3.00 or earlier and has since updated to
version 3.00. To update the UID and GID, navigate to "File Sharing" - "SMB" - "Edit" from Settings and click Update.
• To back up or replicate files to backup or replication destinations with remaining subfolders' access restriction
settings, make sure that the same workgroup name, user IDs, and group IDs are configured between backup or
replication sources and destinations.
41
• If you enable access restrictions for subfolders and then clear the "Read & execute" checkbox under "Allow" on
Windows Explorer for users or groups access permissions, these users or groups cannot be allowed to read and
execute even if subfolders' access restrictions are disabled from Settings. If you deny reading and executing on
the same window, this will remain after disabling access restrictions.
• If the TeraStation's settings have been initialized but you configure the same UID and GID for new users and
groups, the subfolders' access restrictions may be inherited.
Restoring Owner and Permission Settings
If you changed the owner to an unexpected user or lost permissions to specific folder accidentally, restore them by
the procedure below.
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Click Advanced Settings for Subfolders.
42
4 Select a folder to restore permissions from the tree.
Notes:
• Actions will be operated to the selected folder from the folder tree. "The second level folder" means the
subfolder of the selected folder.
• If you select a root shared folder from the tree, the action will not be run to the trashbox folder. To run the
action, select the trashbox folder instead.
5 Select actions and action range to run, then click OK.
43
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.
• Drive capacity is shown in Settings in actual gigabytes. The Properties window in Windows may show GiB instead,
which will be a smaller number.
• 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 5, 6, and 10 are only available for models with 4 or more drives.
RAID 6
RAID 6 arrays are available for TeraStations with 4 or more 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 5
RAID 5 arrays are available for TeraStations with 3 or more 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 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.
RAID 10
RAID 10 arrays are available for TeraStations with 4 or more 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 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.
44
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 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 Storage - RAID in Settings.
Using JBOD
With JBOD, each drive in the TeraStation is addressed separately. To put drives from an array into JBOD, follow the
procedure below.
1 In Settings, click Storage.
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.
45
Changing RAID Mode
To change the RAID mode, first put the drives in JBOD.
1 In Settings, click Storage.

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.
Shutting Down the TeraStation Automatically if Error Occurred
This function will shut down the TeraStation automatically if an error occurs on a drive that is used in a redundant
RAID array.
47
For the TS51210RH series users, it is recommended to enable email notifications if enabling auto shutdown because
the TS51210RH series will extinguish all LEDs when shutting down and the failed drive will not be identified. In such
a case, you can confirm the failed drive number in the notification email.
To configure auto shutdown, follow the procedure below.
1 In Settings, click Storage.
2 Click to the right of "RAID".
3 Click Options.
4 Click Edit.
48
5 Select "Shut down" for "Error Behavior" and click OK.
Rebuilding the RAID Array Automatically
If auto RAID rebuild is enabled, RAID arrays will rebuild automatically after a failed drive is replaced. You may enable
or disable auto RAID rebuild by following the procedure below.
Note: This function is only for the TS51210RH series. Other models will not display this function on Settings.
1 In Settings, click Storage.
2 Click to the right of "RAID".
3 Click Options.
49
4 Click Edit.
5 Select "Yes" for "Automatically Rebuild if New Drive Is Detected" and click OK.
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 or RAID 5 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 drives.
1 In Settings, click Storage.
2 Click to the right of "RAID".
50
3 Choose a RAID array.
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.
Note: To turn the hot spare back into a normal drive, choose Set as a normal drive.
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.
51
1 In Settings, click Storage.
2 Click to the right of "RAID".
3 Choose a RAID array.
4 Set the RAID mode to "RAID 1".

52
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.
10 Click OK when finished.
Adding a Drive to an Existing RAID Array
You can add a drive to a RAID 1 or RAID 5 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 Storage.
2 Click to the right of "RAID".
3 Choose a RAID array.
53
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.
7 Click OK when finished.
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.
1 In Settings, click Storage.
2 Move the RAID scanning switch to the position to enable RAID scanning.
3 Click to the right of "RAID Scanning".
4 Click Edit.
54
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 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 Explorer, where "x" is the USB port where the 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.
Supported file systems for external drives are below:
• FAT32
• EXT3
• XFS
• NTFS
• HFS Plus (read-only)
• exFAT
Connect only one device to each USB port of the TeraStation. Note that only the first partition of a connected USB
drive is mounted. Additional partitions are not recognized.
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 drive is not reconfigured after rebooting the TeraStation, unplug and reconnect it.
• When copying a file that is over 100 MB to a FAT32-formatted USB drive using File Explorer, an error message may
be displayed. In such a case, use an FTP or SFTP connection to copy the file.
55
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
Note: If using the TS51210RH series TeraStations, dismount USB drives from Settings.
When you press the function button, the TeraStation will beep once. Press and hold the button until the TeraStation
beeps again and the button starts blinking blue. It will take about 6 seconds. When the dismount is finished, the
function button will stop blinking and return to glowing. You may now unplug any USB drives safely.
After 60 seconds, the function button will go out and any drives that have not yet been unplugged will be
remounted.
Dismounting from Settings
1 In Settings, click Storage.
2 Click Drives to dismount an internal drive or USB Drives to dismount an external drive.
3 Select the drive to dismount and click Dismount Drive.
56
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 drive check tests the data on a drive in the TeraStation or one that is connected via USB for integrity. Errors are
fixed automatically. With large drives, a drive check may run for many hours. Shared folders cannot be accessed
during a drive check. Do not turn off the TeraStation until the drive check is finished. Use the procedure below to run
a drive check.

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.
Displaying S.M.A.R.T. Information
1 In Settings, click Storage.
2 Click to the right of "Drives".
3 Select a drive to check and click S.M.A.R.T.
59
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.
Checking Drive Condition
For Hard Drives
Attributes with current value or worst 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. In such a case,
replacing that drive is recommended.
For SSD
Confirm the values of the following attributes.
• Lifetime_Remaining - If the current value is less than the threshold, the drive has reached its guaranteed write
capacity (TBW). Replacing the drive is recommended.
• Reallocated_Sector_Ct - If the current value is 99 or less, unrecoverable blocks are detected. If the current value
is 10 or less, the drive should be replaced with a new drive immediately.
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.
60
1 In Settings, click Storage.
2 Select Drives to format an internal drive or USB Drives to format an external drive.
3 Select the drive or array to format, then click Format Drive.
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 drive.
• For drives of 2.2 TB or larger, make sure that the "GPT partition" checkbox is selected.
61
Encrypting Drives
Internal drives (and arrays) can be encrypted with 256-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.
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.

exceeds the set threshold, an email notification will be sent. To configure email notifications for the drive quota,
refer to the "Email Notification" section in chapter 7.
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 drives connected to the TeraStation.
• If both user and group quotas are configured for a user, the most restrictive quota will always apply.

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.
Connection Tool
The Microsoft iSCSI Software Initiator is already installed on your computer. You don't need to download and install
it.
Creating an iSCSI Volume
To use the TeraStation as an iSCSI drive, create a volume first. Configure the TeraStation as described below.
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 Storage.

2 Move the iSCSI switch to the position to enable iSCSI.
3 Click to the right of "iSCSI".
4 Click Create Volume.
5 Enter a volume name, volume description, drive or array where a volume will be created, and volume size. Click
OK when finished.
68
If you enabled LVM for the target drive or array, or selected "File I/O" for the "Backstore" option, the volume size
that you specify here can be changed later. To change the volume size, refer to the "Expanding Volume Sizes"
section below.
6 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
7 Click OK, then Close.
Note: If you click Disable Connection for the selected volume in Storage - 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 static IP address for the TeraStation is
recommended.
Connecting Volumes
To connect a volume, 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.
69
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.
Formatting Volumes
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 drive 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".
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.
70
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 Storage - iSCSI. Current volumes will be listed. If
"Connected" is displayed under "Connection", the volume is currently connected to 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.

Chapter 5 Backup
Backing Up to 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
• A USB drive connected on the TeraStation*
* To back up the subfolders' access restriction settings, the USB drive should be formatted by ext3 or XFS.
You can also configure backup jobs from Easy Admin.
Note: For best results, using a 10GbE port to connect a backup device is recommended.
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 Under "LAN Protocol Support", select the "Backup" checkbox on the "Basic" tab.
78
5 Click OK.
6 Enter the desired characters into the backup device access key field and click OK.
Note: 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. Leave this field blank if you don't want a backup device access key.
Even if you create multiple folders using different backup device access keys, only one access key can be used
on the TeraStation between backup and replication. Folders that are configured with a different access key
cannot be used.
7 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) MTU sizes. If MTU sizes are significantly different, the backup job may not
be properly performed. In such a case, select the default MTU 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".
3 Click Add twice.
4 Click List of Servers.
5 Click Add.
79

5 Click Add.
6 Select backup settings such as date and time to run.
The following types of backup jobs may be selected:
81
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.
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.

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 and a 10GbE port 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 Under "LAN Protocol Support", select the "Backup" checkbox on the "Basic" tab.
91
5 Click OK.
6 Enter the desired characters into the backup device access key field and click OK.
Note: 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. Leave this field blank if you don't want a backup device access key.
Even if you create multiple folders using different backup device access keys, only one access key can be used
on the TeraStation between backup and replication. Folders that are configured with a different access key
cannot be used.
7 Click OK.
Configuring a Replication Task
1 In Settings, click Backup.
2 Click to the right of "Replication".
3 Click Edit.
92
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.
6 Click Add.
93
7 Select the shared folder that will be the replication source and destination, then click OK.
8 Click OK, then 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 decrypted and decompressed on the destination TeraStation.
• 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 or "@" cannot be
selected.
As the replication destination, you can select the first level of shared folders, USB drives, and on/off-subnet NAS
devices' shared folders.
• 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.
94
• 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.
• To inherit the subfolders' access restriction settings to the replication destination, the replication destination
should also support the subfolders' access restrictions. Verify it before creating a replication task.
Synchronizing Between Source and Destination TeraStations
Periodically
To copy files that are saved via other file sharing protocols such as AFP or FTP to the replication destination regularly,
configure "Periodic Sync" from Settings. Follow the procedure below.
1 In Settings, click Backup.
2 Click to the right of "Replication".
3 Click Periodic Sync.
95
4 Select "Daily" or "Weekly" from the "Schedule" drop-down list. If "Daily" is selected, configure the sync period. If
"Weekly" is selected, specify the week days and the sync period.
5 When the configuration is finished, click OK.
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.
96
Before Configuring Failover
Use the same LAN ports for transferring data and configure both TeraStations with static IP addresses for the
purposes of failover. It is recommended to use a 10GbE port for failover. This section explains using an example with
LAN ports 1 and 3.
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 3 ports. Updating is done over this dedicated network path, so updates are quicker and don't interfere
with normal network traffic.

Usage Restrictions
Functional Restrictions
Failover is not available when any of the following functions are enabled:
Replication, sleep mode, encrypted drive volume, LVM volume, iSCSI volume, port trunking, cloud storage*, Dropbox
Sync, hot spare, access restrictions by Active Directory domain
* Even if the function is disabled, the settings may remain if the settings were configured beforehand. Initialize all
settings before configuring failover.
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.
WebAccess*, UPS synchronization, antivirus**, the backup job settings either if specifying shared folders on the
backup TeraStation or USB drives as the backup destination, and USB drives' shared folder settings
* 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.
98
2 Click to the right of "Failover".
3 Click Configure Failover.
4 Select a TeraStation to be the backup destination device and enter its administrator username and password
(the username is "admin", the password is "password" by default).
99
5 Select the LAN port to be used for sharing files and enter a virtual IP address and subnet mask.
About Virtual IP Address:
A virtual IP address is an IP address that will be used for file sharing while failover is configured. By assigning
a different IP address from the one to be assigned to the LAN port, you can access the TeraStation for sharing
files, as well as open Settings using the virtual IP address. This IP address will be inherited to the backup
TeraStation when failover occurs, so you can access the backup TeraStation even if you don't know the backup
TeraStation's static IP address.
Configure an unused IP address for the virtual IP; make sure it uses the same segment as the main and backup
TeraStations.
6 Select the LAN port to be used for transferring data via failover.
7 Configure whether or not to inherit subfolders' access restrictions to the backup TeraStation, then click
Continue.
8 If the administrator username and password is correct, the backup TeraStation will beep. Press and hold the
function button to accept the settings from the main TeraStation. When you press the function button, the
backup TeraStation will stop beeping.
9 Hold it down until the backup TeraStation beeps again.
10 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.
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.
• MTU size settings for main and backup TeraStations should be 1500 bytes. To change the MTU size, navigate to
Network - IP Address - Edit, and change the MTU 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.
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").
100
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.

• Username: The TeraStation's username
• Password: The TeraStation's password
• 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, domain and anonymous users cannot access it.
• Shared folders connected by FTP are available from the "/mnt" directory. The examples of default locations are:
/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.
Cloud Storage
The TeraStation supports Amazon S3, a fee-based online storage service provided by Amazon, and other cloud
storage services that share the Amazon S3 API. Follow the procedure below to configure your TeraStation to use
with your cloud storage service:
Note: Set the TeraStation's time settings to the correct time. Using NTP is recommended. To configure NTP settings
on the TeraStation, refer to the "Name, Date, Time, and Language" section in chapter 7.
Configuring Cloud Storage
1 In Settings, click Web Services.
2 Click to the right of "Cloud Storage".
111
3 Click Add.
4 Select the service name from the drop-down list. Enter the bucket name, access key ID, and secret access key;
select the storage class and the connection protocol, then click OK.
5 Enter a shared folder name to use with the cloud storage service and click OK.
112
6 Under "LAN Protocol Support", select the "Backup" checkbox on the "Basic" tab.
7 Click OK.
8 Enter the desired characters into the field and click OK.
9 Configure the desired shared folder settings, then click OK.
Note: Do not configure a folder that is created through the procedure above as replication destination folder.
Uploading Files to Cloud Storage
To upload files to cloud storage, using backup job is recommended.
1 In Settings, click Backup.
2 Click to the right of "Backup".
113
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.
5 Click Add.
114
6 Select backup settings such as date and time to run. It is recommended to configure a job to run periodically.
If you create a differential backup job and files exist that are only in the destination folder, these files will be
deleted when the job runs. Make sure that files are not saved when creating a backup job.
7 Click Add.
115
8 Select the shared folder that files will be saved to as a source, and the shared folder created through the
"Configuring Cloud Storage" section above as a destination. Click OK.
9 Click OK. Jobs will be added to the backup list.
Notes:
• If a shared folder created through this process is configured to use NFS, it cannot be mounted from an NFS client.
• Files cannot be uploaded to this shared folder using WebAccess.
• If using the cloud storage through a proxy server, click Proxy Settings. In the displayed page, you can select
if using the configured settings or setting identical proxy server. If using the identical proxy server, select
"New settings" and enter the proxy server name, port number, username, and password. Ask your network
administrator for detailed proxy server settings.
• To use after the network was temporarily disconnected, click Reconnect.
• If a file is added to the bucket from a folder other than the TeraStation's remote replication folder, it may take
more than an hour for the file to appear in the TeraStation's remote replication folder. However, when a file is
added to the TeraStation's remote replication folder, it immediately appears in the bucket.
• If you enter an incorrect bucket name and then cancel editing the cloud storage service settings, that wrong
bucket name may still accidentally be registered. If this happens, reconfigure the cloud storage service settings
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 the TeraStation is shut down or restarted immediately after copying
a file to the remote folder, changing the settings, or disconnecting and reconnecting the Ethernet cable, 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.
116
• 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.
Dropbox Sync
The TeraStation supports syncing with Dropbox, the online cloud service. Once connected, you can share
TeraStation files via Dropbox (or Dropbox files via TeraStation). To link your TeraStation with your Dropbox account,
follow the procedure below.

one of the cables is disconnected.
The port trunking modes that can be set in the TeraStation are shown below.
140
Trunking Mode Characteristics
Active-backup Only one NIC slave in the bond is active. A different slave becomes
active if and only if the active slave fails.
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.
ALB
The incoming and outgoing network packets traffic is distributed
according to the current load on each network interface slave. The
receive load balancing is achieved by ARP negotiation.
Note: If the TeraStation is being used as an iSCSI drive, disable iSCSI before changing network settings such as port
trunking. Navigate to Storage - 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.

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 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 for the NFS client.
4 Under "LAN Protocol Support", select the "NFS" checkbox on the "Basic" tab and click OK.
Note the NFS path. It will be used later for accessing data from an NFS client.
5 Click Close.
6 Move the NFS switch to the position to enable NFS.
143
7 Click to the right of "NFS".
8 Click the Client Settings tab.
144
9 Click Add Client.
Note: To delete a client, select the checkboxes of the clients in the lists and click Delete Client.
10 Enter the IP address and hostname of the NFS client, then click OK. You should add all NFS clients to access the
shared folder.
11 Click the NFS Rules tab.
12 Click Add Rule.
13 Choose the folder to restrict access to, and enter the clients that will have restricted access into the "Hosts"
field. Clients may be entered by hostname, IP address, or IP address range. Wildcards are supported. Separate
145
multiple entries with commas. You may assign read-only or read and write access to the listed clients. Rules
override any settings made from the Services tab.
14 Click OK.
15 Click Close.
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.
• If you configure "Guest Permission" to "Forced" on the screen navigating to NFS Rules - Add Client, user ID and
group ID should be 65534 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:
Note: A shared folder whose folder name contains multibyte characters cannot be accessed.
For Solaris 10:
mount -F nfs 192.168.11.10:/mnt/array1/share /mnt/nas
For macOS:
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 and wish to disable SSL encryption, click Normal Connection from the login window.
Encrypting FTP Transfer Data
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.
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.
• Updating the firmware initializes an SSL key.

6 Click OK.
Notes:
• Only one default gateway and DNS address can be configured for all LAN ports. Different network addresses
cannot be assigned to the LAN ports.
• Do not set the IP address of the same segment for all LAN ports. This may cause unstable network
communication.
• Network services such as SMB or AFP will be restarted when the Ethernet cable is disconnected/reconnected or if
a network issue occurs. You can specify the time to delay the restart at the "Services Restarted After" option.
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.
171
Notes Before Use
• To use boot authentication, a Windows PC is necessary to serve as the authentication server.
• When activating boot authentication, the 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 settings initialization
drive by referring to the "Creating an Initialization Drive" subsection 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.
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.

with the authentication server.
If the TeraStation Cannot Be Accessed
If the TeraStation cannot communicate with the authentication server or vice versa, such as in a case of network
failure, the TeraStation will not be accessible. If the TeraStation is not accessible, manually authenticate the
TeraStation by following the procedure below.
Note: The procedure defines an "authentication server administrator" as someone who manages the authentication
server using Boot Authentication Tool, and a "user" as one attempting to access the TeraStation from a remote
location.
174
1 When the user tries to access the TeraStation's Settings and the TeraStation is not available, the screen below
will be displayed. Have the user forward the decryption key to the authentication server administrator.

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 Press the function button on the front of the TeraStation. The TeraStation will beep. The replacement drive is
automatically registered as a hot spare.
To use the replacement drive as a normal drive rather than a hot spare, navigate to Storage - RAID and click the
RAID array, select the new drive, and click Set as a normal drive.
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 Storage - Drives.
(2) Click the drive that was configured as a hot spare, then click Dismount Drive.
(3) Click Rediscover Drive.
(4) Navigate to Storage - 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 Non-Malfunctioning Drive
Do not replace a drive that is not malfunctioning.
If you must change a drive that is not malfunctioning, either first dismount it in Settings, referring to the
"Dismounting Drives" section in chapter 4, 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.
185
Operating in JBOD
All data on that 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.

Chapter 10 Appendix
TeraStation Does Not Work Properly
If an error occurs that prevents the TeraStation from booting up properly, one or more of the following symptoms
may occur:
• The power LED keeps blinking instead of turning into a solid glow.
• An "i" symbol is displayed with the TeraStation icon and the I61 information message is displayed in NAS
Navigator2.
• An "i" symbol is displayed with the TeraStation icon and "EM" is added to your TeraStation's hostname in NAS
Navigator2.
• The LCD panel lights up in red with the "Invalid Firmware" message.
If one or the above occurs, follow the appropriate procedure(s) below to recover from the error.
