Chapter 3 Sharing Files
Configuring Shared Folders
Adding a Shared Folder
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Click Create Folder.
23
Page 25
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 symbol or space as the first character.
• You may create up to 400 shared folders.
• 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.
24
Page 26
• 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:
? [ ] / \ = + < > ; : " , | *
• 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:
• 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.
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.
25
Page 27
Read-Only Shares
By default, new shares are set with read and write access, but you may change the attribute to Read only in Attribute.
Read-only shares and HFS Plus-formatted USB drives will have "(Read Only)" added to comments in Explorer.
Note: Configure read-only file attribute in Settings. Configuring them from within Windows is not supported
and may cause unexpected behavior.
Hidden Shares
If hidden shares are enabled, shared SMB folders will not be displayed in Network, and only certain users are allowed
to access them. To hide a shared SMB folder, follow the procedure below.
1 In Settings, navigate to File Sharing - Folder Setup and choose a shared folder or a USB drive to configure
hidden shares.
2 Select the "Hidden share (SMB only)" checkbox and click OK.
Notes:
• If protocols other than "SMB" or "Backup" under "LAN Protocol Support" are enabled, the hidden shares
option will be grayed out and cannot be selected.
• Configure hidden share attribute in Settings. Configuring them from within Windows is not supported and
may cause unexpected behavior.
To access a hidden folder, open File Explorer in your computer and enter "\\TeraStation name\Shared folder name$\"
for the name. For example, if the TeraStation name is "TSXXX001" and the shared folder name is "share", enter "\\
TSXXX001\share$\" to open it.
Configuring Users

26
Page 28
4 Enter the desired settings, then click OK.
Notes:
• Usernames may contain up to 128 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 symbol or 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 for 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, openldap, proftpd, proxy, pupet, root,
rpc, rpcuser, snmp, sshd, statd, sync, sys, syslog, uucp, www-data
Importing User Information
You can import users in File Sharing - Users by clicking Import CSV File.
Format for user data: Username (required), password (required), and user description (optional).
Example 1: Importing usernames, passwords, and comments
27
Page 29
username1,password1,comment1
username2,password2,comment2
username3,password3,comment3
Example 2: Importing usernames and passwords
username1,password1,
username2,password2,
username3,password3,
Guidelines:
• Use commas (,) as separators. Do not put spaces before or after commas. If you don't want user descriptions, use
a comma after password at the end.
• If a line has an incorrect format, the user on that line will not be registered.
• If a username already exists, the new user information will overwrite the old information.
• Do not use commas (,) in the username, password, or user description.
Note: Imported users are added to the "hdusers" group automatically.
Adding a Group
1 In Settings, click File Sharing.
2 Click to the right of "Groups".
3 Click Add Group.
28
Page 30
4 Enter the desired settings, then click OK.
Notes:
• Group names may contain up to 20 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 for a group name as these words are reserved for internal use by the
TeraStation: adm, admin, administrator, all, apache, bin, daemon, disk, ftp, ftpuser, guest, halt, hdusers, kmem,
lp, mail, man, mysql, news, nobody, nogroup, none, operator, root, shadow, shutdown, sshd, sync, sys, tty,
users, utmp, uucp, www
29
Page 31
Configuring Access Restrictions
You may restrict access to specific shared folders, including external USB drives.
Notes:
• Access restrictions can be set separately for each shared folder, but not for folders within the shared folders.
• Configure access restrictions through Settings. Configuring access restrictions through Windows is not
supported and may cause unexpected behavior.
• You can also configure users, groups, and shared folders from Easy Admin by clicking Access Restrictions.
• Shared folders with limited access can still be used as backup destinations.
• If you change access restrictions for a user or group while they are accessing files, unexpected behavior may
result.
Local Users and Groups
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Click the shared folder that you want to set access restrictions for.
4 Click Edit.
5 Enable "Access Restrictions".
6 Select the level of access for the user or group you added.
30
Page 32
: Read and write access allowed : Read access allowed : Access prohibited
7 Click OK.
Notes:
• The example above shows access restriction by user. To restrict access by group, click the Local Groups tab
and select group permissions.
• If both read-only and read and write permissions are given to a user, the user will have read-only access. The
most restrictive access always applies.
• For an access-restricted shared folder, if you change the access restrictions of all users and groups from read
and write or read only to access prohibited from the user or group list page in Settings, that shared folder can
only be accessed by admin users and groups.
Active Directory
If there is an Active Directory environment, the TeraStation will use account information from the Active Directory
domain controller to set access restrictions for TeraStation's shared folders. There is no need to perform individual
account management for the TeraStation. If multiple TeraStations are installed on the network, the account
information is centrally managed in Active Directory, greatly reducing the operations required for installation and
management.
Notes:
• If usernames or group names from Active Directory include multibyte characters, you will not be able to
configure access restrictions for them.
• The TeraStation supports a domain environment with a maximum of 1000 users and 1000 groups.

: Read and write access allowed : Read access allowed : Access prohibited
12 Click OK.
Notes:
• To have the TeraStation join an Active Directory domain, configure it to use a DNS server that can resolve
names for the Active Directory domain.
• After building an Active Directory domain, the administrator password for joining the domain must be
changed at least once, or joining the Active Directory domain will fail.
• The DNS name and NetBIOS name of Active Directory domains should be identical.
• If both read-only and read and write permissions are given, the user will have read-only access. The most
restrictive access setting will apply.
• If there is a difference of more than 5 minutes between the TeraStation's clock and the domain controller's
clock, joining the domain or authenticating domain users and groups may fail. For best results, use an NTP
server to set the time for all network devices.
• To use the TeraStation as a member server in an Active Directory domain, the TeraStation should be logged
in to the domain and accessed from a computer that is not a member of the domain with a valid domain
account.
• If the TeraStation is a member server of an Active Directory domain, you cannot connect as a guest user via
AFP.
• If your TeraStation is a member server in an Active Directory domain and you change the authentication
method to "Workgroup", the account on the domain controller will not be deleted automatically.
• If FTP is enabled, local and domain group access restrictions from the AD network do not work. Use user
access restrictions instead.
33
Page 35
• For an access-restricted shared folder, if you change the access restrictions of all users and groups from read
and write or read only to access prohibited from the user or group list page in Settings, that shared folder can
only be accessed by admin users and groups.

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.
TeraStation Default RAID Mode Available Modes
TS5410DN, TS5410RN RAID 5 RAID 5, 6, 10, 1, 0, and JBOD
TS5210DN RAID 1 RAID 1, 0, and JBOD
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 4-drive models.
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.
35
Page 37
RAID 1
Combines 2 or more drives into a mirrored array. The available space in the array is the capacity of a single drive.
Identical data is written to each drive. If a drive is damaged, data can be recovered by replacing the damaged drive.
As long as one drive in the array remains undamaged, all data in the array can be recovered.
RAID 0
Combines 2 or more drives into a single array. The usable drive space is the total space of all drives used. This simple
RAID mode offers faster performance than RAID modes that include parity. If a single drive in the array fails, then all
data in the array is lost.
JBOD
This mode uses the 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.

use a hot spare, you need an extra drive that's not part of any array and a RAID 1 or RAID 5 array.
38
Page 40
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.

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" under the TeraStation in "Network", 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:
43
Page 45
• FAT32
• EXT3
• XFS
• NTFS
• HFS Plus (read-only)
• e xFAT
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.
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
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.
44
Page 46
3 Select the drive to dismount and click Dismount Drive.
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.
1 In Settings, click Storage.
2 Select Drives to check an internal drive or USB Drives to check an external drive.
45
Page 47
3 Select the drive or array to test, then click Check Drive.
4 Click Check. You have the option of deleting information files from macOS during the check if desired.
S.M.A.R.T.
S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) monitors internal drives to detect and report
various indicators of reliability, in the hope of anticipating failures. When a failure is anticipated by S.M.A.R.T., the
user may choose to replace the drive to avoid outages and data loss. Follow the procedure below to check S.M.A.R.T.
information for the TeraStation's internal drives.
Note: S.M.A.R.T. information is only available for internal drives.
1 In Settings, click Storage.
2 Click to the right of "Drives".
46
Page 48
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.
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.
47
Page 49
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.
48
Page 50
Encrypting Drives
Internal drives (and arrays) can be encrypted with 128-bit AES during formatting. Encrypted drives and arrays are
then readable only from that specific TeraStation. To decrypt a drive or array, clear the "Encryption" checkbox and
format it again.
Erasing Data on the TeraStation Completely
Under some circumstances, data from formatted drives can be recovered. The drive erasure process in this section
does a much more thorough job of erasing data. This procedure is recommended for removing all data from a drive
in a way that makes it nearly impossible to recover with current tools. The TeraStation will then be in the following
state:
• All drives in JBOD
• An empty shared folder on each drive
• All settings returned to their default values
• All logs deleted
If you remove a drive and then erase all data on the TeraStation, the LCD panel will show the E22 error message and
the number of the removed drive. You can still use the TeraStation.
Follow the procedure below to completely and permanently erase all data from your TeraStation.
1 In Settings, click Management.
2 Click to the right of "Restore/Erase".
3 Click Erase TeraStation.
4 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
49
Page 51
5 All data on the TeraStation will be permanently erased.
Drive Quotas
You can set a drive quota to limit drive space for each user or group. You can also set a threshold. If the drive space
exceeds the set threshold, an email notification will be sent. To configure email notifications for 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.

by the TeraStation: array x, authtest, disk x, global, homes, info, lost+found, lp, mediacartridge x, msdfs_root,
mt-daapd, printers, ram, spool, usbdisk x. Any instances of "x" denote a number (for example: array1 or disk3)
• If an LVM volume could not be mounted, try restarting the TeraStation. If an issue still exists, delete and
recreate the LVM volume. Deleting the LVM volume will erase data on the volume.
Using the TeraStation as an iSCSI Device
Introduction
iSCSI is a protocol for carrying SCSI commands over IP networks. Unlike traditional SAN protocols such as Fibre
Channel, which requires special-purpose cabling, iSCSI can be run over long distances using existing network
infrastructure. Normal Windows formatting such as NTFS is supported.
Differences Between NAS and iSCSI
With iSCSI, the TeraStation is connected to a single computer, such as a server. Other computers on the network
access files on the TeraStation through the computer it's connected to. The TeraStation can be used as a local drive
from Windows Server. Features of Windows Server such as Active Directory can be used normally.
As a NAS, the TeraStation is a server, and computers (including other servers) on the network can access shared
folders on it directly. A separate server is not required, and features such as backup are built-in.
Network Configuration
Use gigabit or faster network equipment with iSCSI. For best results, a dedicated network for iSCSI is recommended,
separate from the regular network. Use fixed 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)

55
Page 57
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 fixed 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.

57
Page 59
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 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.

• Another TeraStation on the network
You can also configure backup jobs from Easy Admin.
Note: For best results, using LAN port 3 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 Click Edit.
5 Under "LAN Protocol Support", select the "Backup" checkbox and click OK.
Note: If a backup access password 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 LinkStation or TeraStation. To
configure a backup access password, enter it into the "Backup Access Password" box. Leave this box blank if you
don't want a backup access password.
Backing Up to a LinkStation or TeraStation on Another Network When Connected
via 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 destination LinkStation or TeraStation.
If your setup meets the requirements below, you don't have to configure these settings:
• The source and destination TeraStations are on the same network.
• No backup access password is set for the destination TeraStation.
• No TeraStation from outside the subnet or connected by a VPN is used.

Page 68
4 Click Add under "Off-Subnet Devices", enter the IP address or hostname of the destination LinkStation or
TeraStation, and click Close.
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
destination, and folders in these devices cannot be used as backup destination folders.
Configuring a Backup Job
1 In Settings, click Backup.
2 Click to the right of "Backup".
67
Page 69
3 Click Create New Job.
Note: Up to 8 backup jobs can be configured.

The following types of backup jobs may be selected:
68
Page 70
Type Files included
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
Normal backup
Overwrite (incremental)
Overwrite (differential)
Management backup
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.
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.
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.
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.
72
Page 74
Notes:
• For best results, use static IP addresses and LAN port 3 for connecting both replication TeraStations (source
and destination).
• Replication source data is copied to the replication destination folder with a differential overwrite. Any data
that is not in the replication source will be overwritten.
Preparing a Replication Destination
First, configure a folder as a replication destination.
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Choose the folder to set as a replication destination.
4 Click Edit.
5 Under "LAN Protocol Support", select the "Backup" checkbox and click OK.
Note: Do not configure a backup access password for the shared folders. Folders with a backup access password
set cannot be selected as replication destinations.
Configuring a Replication Task
1 In Settings, click Backup.
2 Click to the right of "Replication".
73
Page 75
3 Click Edit.
4 Click Add.
5 Click Browse under "Replication Source".
74
Page 76
6 Select the shared folder that will be the replication source, then click OK.
7 Click Browse under "Replication Target".
8 Select the shared folder that will be the replication destination, then click OK.
9 Click OK.
10 Click Ye s.
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
75
Page 77
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
NASs 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.
• 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.
Synchronizing Between Source and Destination Units 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".
76
Page 78
3 Click Periodic Sync.
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.
Data on both TeraStations stays up-to-date.
BackupMain
Switches automatically if failure occurs.
Failover will activate during any of the following situations:
• The backup TeraStation cannot detect the main TeraStation within a specified time
77
Page 79
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 drive volume, LVM volume, iSCSI volume, port trunking, cloud storage, Dropbox
Sync, hot spare, access restrictions by Active Directory domain
Setting Restrictions
The following functions will not be available while failover is enabled:
Initializing settings, changing the RAID settings, formatting drives, iSCSI volume, changing the backup 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.
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, SNMP (when using SNMPv3), 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
* After failover, re-register your BuffaloNAS.com account for WebAccess on the new main TeraStation if LAN port 1 is
assigned a new static IP address or using DHCP. If the new main TeraStation inherits the original static IP address for
LAN port 1, WebAccess settings will be transferred and you will not need to reconfigure it.
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. However, the UPS
settings of the main TeraStation will not be copied to the backup TeraStation.
78
Page 80
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
Use the same LAN ports for transferring data and it is recommended that both TeraStations are configured with
static IP addresses for the purposes of failover. It is also recommended to use LAN port 3 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.

80
Page 82
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).
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, then click Continue.
7 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. Hold it down until the backup TeraStation beeps again.
8 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.
• Ethernet frame size settings for main and backup TeraStations should be 1500 bytes. To change the Ethernet
frame size, navigate to Network - IP Address - 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 on the LCD panel, navigate to Backup - Replication and click Resync.
81
Page 83
• 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 the Advanced Settings tab on 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.
Synchronizing Between Main and Backup Units Periodically
To copy files that are saved via other file sharing protocols such as AFP or FTP to the backup TeraStation regularly,
configure "Periodic Sync" from Settings. Follow the procedure below.
1 In Settings for the main TeraStation, click Backup.
2 Click to the right of "Failover".
3 Click the Periodic Sync tab.
82

Chapter 6 Remote Access
WebAccess
WebAccess is a software utility 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.
Notes:
• You can also configure WebAccess from Easy Admin.
• WebAccess supports downloading up to 60,000 files at a time. Attempting to download up to 60,000 files at a
time may result in unexpected behavior.

Accessing the TeraStation with an Anonymous User
• To allow anonymous access to your FTP share, disable access restrictions.
• To access the TeraStation via anonymous FTP, configure your FTP client software with the following settings:
Hostname: IP address of the TeraStation
Username: anonymous
Password: any character string
Port: 21
*If the TeraStation joins a domain, anonymous users cannot access it.
Notes:
• 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".
3 Click Add.

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 you shut down or restart the TeraStation immediately after
copying a file to the remote folder, the file may not be uploaded to the bucket. Try copying the file again if
this occurs.
• If you encounter any upload or download errors, click Error Log. The log will display the filename and
operation during which the error occurred.
• If uploading fails, try copying the file again. If it still fails, click Reconnect or set the cloud storage switch to off
and on again, then restart the cloud storage service.
• If transferring or accessing 1 TB or more files from cloud storage, make sure there is enough free space on
the TeraStation for temporary file caching. For example, when uploading 1 TB of files to cloud storage, it is
recommended to keep at least 2 TB of free space available.
