Chapter 3 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.

Configuring Access Restrictions on Users and Groups

Adding a Shared Folder

1 In Settings, click the icon to the right of “Folder Setup”.
2 Click Create Folder.
3 Configure the desired settings, then click OK at the bottom of the window.
21
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.
• The names of shared folders should not use characters from more than one language. For example, mixing Japa­nese and Korean characters in names is not supported.
• If multi-byte characters are used in shared folder names, configure the client language to match the characters in Management - Name/Time/Language.
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 the recycle bin in Settings.
Accounts
Your TeraStation’s username and password should be the same as your Windows username and password. If they are different, you may not be able to access folders on the TeraStation with access restrictions configured.
22
Read-only Shares
By default, new shares are set with read & write access, but you may change the attribute to “Read-only” in “Shared Folder Attributes”. Read-only shares and HFS+ formatted USB hard drives will have “Read-only” added to the shared folder description.
Hidden Shares
To hide a shared SMB folder, select “Hidden Share (SMB Only)” and click OK. To open a hidden folder, click Start - Search programs and files and enter “\\TeraStation name\Shared folder name$\” for the name. Example: If the TeraStation name
is “TS-XX001” and the shared folder name is “share”, then enter “\\TS-XX001\share$\” to open it.
Note: FTP, SFTP, and Mac AFP folders cannot be hidden.

Adding Users

1 In “File Sharing”, select Users.
2 Click Create User.
3 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.
• For Windows 8, use a local username instead of your Windows Live ID.
• 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.
23
• The description may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do not use a symbol or space as the first character.
• When setting users with access privileges, a maximum of 300 users, including “admin” and “guest”, can be regis­tered in the TeraStation.
• 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.
Importing User Information
You can import users in File Sharing - Users by clicking Import CSV File. Existing users will be overwritten.
Format for user data: Username (required), password (required), and user description (optional).
Examples:
username1,password1,comment1
username2,password2,comment2
username3,password3,comment3
Guidelines:
• Use commas (,) as separators. Do not put spaces before or after commas.
• If a line has an incorrect format, the user on that line will not be registered.
• If a username 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.
Shared Folder Owners
To confirm the owner of a shared folder from Windows XP, from the Properties screen of the file or folder, open a new window from the Security tab. Click Advanced, then click the Owner tab.

Adding Groups

1 In “File Sharing”, select Groups.
2 Click Add Group.
3 Enter settings, then click OK.
24
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.

Access Restrictions

1 In “File Sharing”, select Folder Setup.
2 Click the shared folder that you want to set access restrictions for.
25
3 Click Edit.
4 Enable “Access Restrictions”.
5 Select the level of access for the user or group you added.
: Read and write access allowed : Read access allowed : Access prohibited
6 Click OK.
Notes
• The example above shows access restriction by user. To restrict access by group, click the Local Groups and select group permissions.
• If both read-only and read & write permissions are given to a user, the user will have read-only access. The most restrictive access always applies.
• The following characters are handled differently by Mac OS and Windows. Avoid using these characters when sharing data between Mac OS and Windows:
• Windows does not support some characters that Mac OS and the TeraStation allow. If you create a filename on a Mac with any of the following characters, it will not display correctly on a Windows computer. With OS X 10.2 or later, you may have to connect to the TeraStation via AFP in order to display or copy any of the following characters.
? [ ] / \ = + < > ; : “ , | *
• Do not use any of the following words as a username or group name: root, bin, daemon, sys, adm, tty, disk, lp, sync, shutdown, halt, operator, nobody, mail, news, uucp, ftp, kmem, utmp, shadow, users, nogroup, all, none, hdusers, admin, guest, man, www, sshd, administrator, ftpuser, apache, mysql, splx
• Do not use any of the following words as the name of a shared folder. These words are reserved for internal use by the TeraStation: info, spool, lost+found, global, printers, homes, lp, authtest, ram, msdfs_root, mt-daapd, usbdisk# (where # is a number, for example: usbdisk1)
• Don’t use the following unsupported characters in shared folder names, workgroup names, or filenames:
• File and folder names may contain up to 255 single-byte characters.
26
• Configure hidden and read-only file attributes in Settings. Configuring them from within Windows is not supported and may cause unexpected behavior.
• Folder and workgroup names whose names contain non-Roman characters may not be displayed correctly.
• If shared folders are accessed from a Macintosh, information files for the Macintosh may be generated automatically. Do not delete these files. If they are deleted using Windows, this may prevent further access from a Macintosh.
• If an SMB connection is used with OS X 10.3.9, the names of mounted volumes may appear as unreadable characters in Finder and other applications. This is not a problem with the filename or data.
• With OS X 10.5 to 10.5.6, Spotlight searches are not supported over AFP connections. Use SMB connections or upgrade to OS X 10.5.7 or later.
• The TeraStation belongs to the default zone in AppleShareServer; 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.
• Hard drive capacity is shown in Settings in actual gigabytes. The Properties window in Windows may show GiB instead, which will be a smaller number.
• 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:
- The preset data (TeraStation name, user, and group) 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.
• 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.

Active Directory

The TeraStation can join an Active Directory domain. Up to 1000 domain users and 1000 groups may be downloaded from Active Directory.
Note: If usernames or group names from Active Directory include multi-byte characters, you will not be able to configure access restrictions for them.
1 In Settings, select Network.
2 Select Workgroup/Domain.
3 Click Edit.
4 Select “Active Directory”, then click Next.
27
5 Click Yes.
6 Enter the desired settings, then click OK.
7 Choose Folder Setup.
8 Click a shared folder that you want to set access restrictions for.
9 Click Edit.
10 Enable “Access Restrictions”.
11 Select the level of access for the user or group:
: Read and write access allowed : Read access allowed : Access prohibited
12 Click OK.
Notes:
• If both read-only and read & write permissions are given, the user will have read-only access. The most restrictive access setting will apply.
• 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 there are more than 5 minutes difference between the TeraStation’s clock and the domain controller’s clock, joining the domain or authenticating domain users and groups may fail. For best results, use an NTP server to set the time for all network devices.
28
• The TeraStation supports a domain environment with a maximum of 1000 users and 1000 groups. 10,000 users and 10,000 groups can be downloaded from the domain controller but are not supported.
• 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.
• When the TeraStation joins an Active Directory domain, FTP is disabled. Before use FTP, move the FTP switch back
to the position.
• Don’t disable the SMB protocol while Active Directory is used for access restrictions. If you do, you will need to en­able SMB again and reconfigure AD from scratch.

NT Domains

In an NT domain environment, the TeraStation uses account information from the NT domain server to set access restrictions for files and folders on the TeraStation. There’s no need to perform individual account management for the TeraStation. If multiple TeraStations are installed on the network, the account information is centrally managed in the NT domain, greatly reducing the operations required for installation and management.
Note: A maximum of 1000 domain users and 1000 groups can be downloaded from an NT domain server.
1 Create an account on the domain controller for the TeraStation.
2 In Settings, click Network.
3 Select Workgroup/Domain.
4 Click Edit.
5 Select “NT Domain”, then click Next.
Note: To use Active Directory from Windows 2000 or Windows Server 2003, select “Active Directory” instead of “NT Domain”.
6 Click Yes.
7 Enter settings and click OK.
29
8 Click to the right of “Folder Setup”.
9 Click a shared folder for which you want to set access restrictions.
10 Click Edit.
11 Enable “Access Restrictions”.
12 Select the level of access for “Domain Users” or “Domain Groups” you added.
: Read and write access allowed : Read access allowed : Access prohibited
13 Click OK.
Notes:
• If you change the TeraStation’s name, you will no longer be able to use domain users and groups or access restric­tions. To repair this, rejoin the domain.
• If both read-only and read & write permissions are given to a user, the user will have read-only access.
• If a domain username is more than 20 bytes long, the TeraStation truncates it to 20 bytes.
• The TeraStation supports a domain environment with a maximum of 1000 users and 1000 groups. 10,000 users and 10,000 groups can be downloaded from the domain controller but are not supported.
• To use the TeraStation as a member server in an NT domain, the TeraStation should be logged in to the domain and accessed from a computer that is not a member of the domain with a valid domain account.
• If the TeraStation is a member server of an NT domain, you cannot connect as a guest user via AFP.
• When you change the user or group settings on the domain controller, these changes may not take effect imme­diately on the TeraStation until it is rebooted.
• If your TeraStation is a member server in an NT domain and you change the authentication method to “Work­group”, the account on the domain controller will not be deleted automatically.
30
• If the TeraStation has joined a domain network, you cannot connect to it via FTP.
• Don’t disable the SMB protocol while an NT domain server is used for access restrictions. If you do, you will need to enable SMB again and reconfigure the NT domain settings from scratch.

Delegating Authority to an External SMB Server

TeraStations on your network can be linked to an authentication server for centralized management of user accounts and passwords. The authentication server should be a LinkStation or another TeraStation.
Notes:
• Other external SMB authentication servers are not supported. Use a TeraStation or a LinkStation for the authenti­cation server.
• When saving changes to the external authentication server settings, clicking Yes will convert all local users to external authentication users. If external authentication is disabled, local user passwords will need to be reconfig­ured.
• Disable SMB2 before using external authorization with Windows 8.
• Using external authentication may require the default security settings in Windows to be changed. An easy way to do this is to run the File Sharing Security Level Change Tool, available from www.buffalotech.com. This simple tool will let you change or restore your Windows security settings to work with external authentication.
1 In Settings, click Network.
2 Choose Workgroup/Domain.
3 Click Edit.
4 Select “Workgroup”.
To use in a domain environment, select “NT Domain” or “Active Directory”.
5 Click Yes.
6 Enter a workgroup name. Select “Assign authorization to external SMB server” and enter the authentication server’s
IP address (recommended) or name. Check “Automatic user registration” and “Use shared folder for authorization testing” and enter the name of the folder to use. Click OK.
31
7 A shared folder for authentication will be created on the TeraStation. Users registered to the authentication server
are automatically registered as users on the TeraStation when they open the shared folder for authentication. You can also register users directly. Connect to the authentication folder via SMB, not FTP or AFP.
Note: Automatic user registration may not work with OS X 10.8 (or later) the first time. If this occurs, try rebooting the TeraStation and access the authentication testing shared folder again.
8 Choose Folder Setup.
9 Choose a shared folder to set access restrictions on.
10 Click Edit.
11 Enable “Access Restrictions”.
12 Select the level of access:
: Read and write access allowed : Read access allowed : Access prohibited
13 Click OK.
Notes:
• If both read-only and read & write permissions are given to a user, the user will have read-only access.
• If access restrictions are set for users or groups from the authentication server, guest and anonymous connec­tions will not be possible with AFP or FTP connections.
• Users who are automatically registered belong to the “hdusers” group. They can be added to other groups from within group settings.
32
• The names of registered users are listed in “Users” - “External Users”. To delete a user who was registered automati­cally, select that user and click Delete External User.
• When connecting through AFP or FTP, always use an IP address. Using a server name may cause problems with authentication.
• To specify a server from another subnet, enter its IP address.
• Use AFP to access access-limited shared folders from OS X 10.7 instead of SMB. Enable “AFP (Mac)” under “LAN Protocol Support” on the destination folders to use AFP.
• Use OS X 10.5 or later with external authentication. Earlier versions of OS X and Windows Server 2012 aren’t sup­ported.

Chapter 4 Managing Your Storage

RAID Arrays

TeraStations support many types of RAID. The type of RAID arrays available for use depends on how many drives are installed in your TeraStation.
TeraStation Default RAID Mode TS3400D TS3400R TS3200D RAID 1
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.
• After the RAID mode is changed (except when creating a RAID 0 array or JBOD), the TeraStation performs a RAID check that will take about 10 hours per TB. File transfers are slower during this period. While the message “RAID I17 ARRAYx Resyncing” is displayed on the LCD panel, do not turn off the TeraStation. If you do, the RAID check starts over.
• If the TeraStation is restarted or shut down while changing the RAID mode, the message displayed on the LCD panel changes from I46 or I47 to I18.
RAID 5
JBOD
This mode uses the hard drives inside the TeraStation as individual drives. The disk space you can use is the total capacity of all drives in the TeraStation. If any drive is damaged, then the data on that drive is lost.
RAID 0
Combines 2 or more hard drives into a single array. The usable disk space is the total space of all drives used. This simple RAID mode offers faster performance than RAID modes that include parity. If a single drive in the array fails, then all data in the array is lost.
RAID 1
Combines 2 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 5
RAID 5 arrays are available for TeraStations with 3 or more hard drives. RAID 5 combines 3 or more drives into a single array. The usable space is equal to the sum of the capacity of the hard drives minus the capacity of one drive. For example, if 4 drives are combined into a RAID 5 array, the usable space is the sum of 3 drives. If one drive in the array is
*
34
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 6
RAID 6 arrays are available for TeraStations with 4 or more hard drives. RAID 6 combines 4 or more drives into a single array. The usable space is equal to the sum of the capacity of all drives minus the capacity of two drives. For example, if 4 drives are combined into a RAID 6 array, the usable space is the sum of the capacity of 2 drives. If 2 drives in the array are damaged, you can recover data by replacing them. If 3 or more drives are damaged, your data is lost.
RAID 10
RAID 10 arrays are available for TeraStations with 4 or more hard drives. In this mode, mirrored pairs of drives in RAID 1 arrays are combined into a RAID 0 array. The usable space is equal to the capacity of the smallest drive multiplied by the number of hard drives divided by 2.
*Modes marked with an asterisk are available for TS3400D and TS3400R TeraStations only.
*
*

Working with RAID Arrays

To change RAID settings, navigate to Drives - RAID in Settings.

Using JBOD

With JBOD, each hard drive in the TeraStation is addressed separately. To put drives from an array into JBOD mode, follow the steps below.
1 Select RAID.
2 Select the array to delete.
3 Click Delete RAID Array.
Once JBOD is configured, create shared folders on each drive to use them.

Changing RAID Mode

To change the RAID mode, first put the drives in JBOD mode.
35
1 Select RAID.
2 Click the array to delete.
Note: If the “RAID Mode” field is blank, the array is already in JBOD mode. Proceed to step 7.
3 Click Delete RAID Array.
4 The “Confirm Operation” screen will open. Enter the displayed number, then click OK.
5 Click OK.
6 Choose the array to configure.
7 Select a RAID mode and the drives to be used, then click Create RAID Array.
8 Step through the wizard to create the array.
Notes:
• You can also configure RAID settings from Easy Admin.
• After changing the RAID mode, create a shared folder.

Configuring a Hot Spare

If you have a hot spare configured and an array fails, the TeraStation immediately switches over to the hot spare. To use a hot spare, you need an extra drive that’s not part of any array and a RAID 1 or RAID 5 array.
36
Notes:
• All data on the hot spare drive is deleted when it is configured as a hot spare and again when it changes from a spare to a drive in the array.
• A hot spare cannot be configured for TeraStation models with only two hard drives. Use RAID 1 instead.
1 In Settings, click Drives.
2 Choose RAID.
3 Choose a RAID array.
4 Click Set as a hot spare.
5 Step through the wizard.
6 When the “Confirm Operation” screen opens, enter the confirmation number and click OK.
Notes:
• To turn the hot spare back into a normal disk, choose Set as a normal disk.
• If a drive fails in the RAID array before it is rebooted, the hot spare will not automatically replace the failed drive. In this case, follow the steps below to repair the array.
(1) In Settings, navigate to Drives - Drives.
(2) Select the drive that was configured as a hot spare, then click Dismount Disk.
(3) Click Rediscover Disk.
(4) Navigate to Drives - RAID.
(5) Select the RAID array to repair.
(6) Select the drive that was previously configured as a hot spare, then click “Recover RAID Array”.
This will rebuild the RAID array.

RMM (RAID Mode Manager)

With RMM, you can create or expand a RAID array without erasing the data on the drives.
37
Changing from JBOD to RAID 1
Hard drives that aren’t in a RAID array show “Normal (RMM available)”. You must have at least two drives available in JBOD (not in a RAID array) to build the RAID 1 array with RMM.
1 Select the drive on which you do not want to erase data.
2 Check “Add a disk to RAID array with RMM. Your data will be preserved.”.
3 Select the drive to add to the RAID array.
4 Click Create RAID Array. The “Confirm Operation” screen will open.
5 Enter the confirmation number, then click OK.
Adding a drive to an existing RAID array
You can add a drive to a RAID 1 or RAID 5 array. Drives that can be added to the RAID array show “Normal (RMM available)” or “JBOD.”
Notes:
• Each drive must have the same capacity.
• RMM can be used to expand an array by one drive per operation. To expand by two or more drives, RMM must be performed multiple times.
1 Click Drives.
2 Click RAID.
3 Choose a RAID array.
38
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

RAID maintenance scans your RAID array for bad sectors and if it finds any it automatically repairs them. RAID 1, RAID 10, and RAID 5 arrays are supported for most TeraStation modes. For best results, run RAID maintenance regularly.
1 In Settings, click Drives.
2 Click the icon to the right of “RAID Scanning”.
3 Click Edit.
4 Select the schedule for running RAID maintenance, then click OK.
Notes:
• Check “Immediately” to run RAID maintenance immediately.
• To stop a RAID scan, click Cancel RAID Scan.
5 Move the RAID scanning switch to the position to enable RAID scanning.
39

Adding an External Hard Drive

Connecting an External Drive
Your TeraStation includes USB ports (the number of ports depends on your model), and you can connect external drives to these ports. Once connected they appear as shared folders on the TeraStation. Formatted drives are detected automatically. Unformatted drives should be formatted in Settings.
After a USB drive is recognized, Windows adds “usbdisk X” under the TeraStation in “Network”, where “X” is the USB port where the hard drive is connected.
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)
• Digital cameras
• USB-connected UPSs
• USB printers
Buffalo external USB drives are recommended.
These devices are not supported:
• DUB and DIU series drives
• Hubs, mice, and keyboards
Connect only one device to each USB port of the TeraStation. Some external drives with automatic power-on don’t turn on automatically when connected to the TeraStation. Use their manual power switch to turn them on. Be sure to connect only one bus-powered drive at a time. If there is insufficient bus power for your USB drive, connect its AC adapter. Note that only the first partition of a connected USB hard drive is mounted. Additional partitions are not recognized.
Notes:
• Hubs are not supported. Connect a single USB drive to each USB port.
• Backup data from Mac OS may include characters that cannot be written to FAT16 or FAT32 drives such as “.DS_ Store”. For best results, reformat the drive before using it as a backup target.
• The TeraStation is compatible with most USB 2.0 external hard drives. Compatible USB 3.0 external drives include HD-LBU3 series, HD-LXU3 series, HD-PCTU3 series, HD-PNTU3 series, HD-PZU3 series (as of May 2013)

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.
Dismounting with the Function Button
If the TeraStation is on, hold down the function button for 8 seconds. The function button will flash as all external drives are dismounted, which will take about 30 seconds. When the dismount is finished, the function button will stop flashing and glow steadily. You may now unplug any USB drives safely.
Note: After 60 seconds, the function button’s LED will go out and any drives that have not yet been unplugged will
40
be remounted.
Dismounting from Settings
1 In Settings, click Drives.
2 Select Drives to dismount an internal drive or USB Drives to dismount an external drive.
3 Select the drive to dismount and click Dismount Disk. It will take about 30 seconds for the drive to be dismounted.
4 When the following message is displayed, it is safe to unplug the drive.
Note: To remount the drive, unplug it and then plug it back in.

Checking Drives

A disk check tests the data on a drive in the TeraStation or connected via USB for integrity. Errors are fixed automatically. With large drives, a disk check may run for many hours. Shared folders cannot be accessed during a disk check. Do not turn off the TeraStation until the disk check is finished. Use the procedure below to run a disk check.
1 In Settings, click Drives.
2 Select Drives to check an internal drive or USB Drives to check an external drive.
41
3 Select the drive to test, then click Check Disk.
4 Click Check. You have the option of deleting information files from Mac OS during the check if desired.

Formatting Drives

Note: 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 “Erase Data on the TeraStation Completely”.
1 In Settings, click Drives.
2 Select Drives to format an internal drive or USB Drives to format an external drive.
3 Select the drive to format, then click Format Disk.
42
4 Select a format type, then click Format.
5 The “Confirm Operation” screen will open. Enter the displayed number, then click OK.
6 Depending on the size of your drive, the format may take several minutes or several hours to complete.
“Formatting” will be displayed on the LCD display until the format is complete.
Notes:
• Do not turn off or disconnect power to the TeraStation while formatting a hard drive.
• Format drives of 2.2 TB or larger with GPT partitions. For many drives, this option will be enabled automatically during format.

Encrypting Drives

Internal drives (and arrays) can be encrypted with 128-bit AES during formatting. Encrypted drives and arrays are then readable only from that specific TeraStation. To unencrypt a drive or array, uncheck “Encryption” and format it again.
43

Media Cartridges

If configured as a media cartridge, an internal drive can be used as a removable storage device in the same way as an external drive. Media cartridges can be unplugged and connected to a different TeraStation with all data intact.
To configure a drive as a media cartridge, check “Media Cartridge” during formatting. To return it to its original state, uncheck “Media Cartridge” and reformat the drive.
Media cartridges do not support:
• RAID arrays
• LVM volumes
• Access restrictions
• Direct connection to a Windows computer

Erase Data on the TeraStation Completely

Under some circumstances, data from formatted drives can be recovered. The disk erasure process in this section does a much more thorough job of erasing data. This procedure is recommended for removing all data from a drive in a way that makes it nearly impossible to recover with current tools. All data on the drives is completely erased. The TeraStation will then be in the following state:
• All drives in JBOD mode
• 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 will show the error “HDx Error E22 HDx Can’t Mount” where X is the hard drive you removed. You can still use the TeraStation.
44
1 In Settings, click Management.
2 Select Restore/Erase.
3 Click Erase TeraStation.
4 The “Confirm Operation” screen will open. Enter the displayed number, then click OK.
5 All data on the TeraStation will be permanently erased.

Disk Quotas

Notes:
• When using quotas, disable the recycle bin or empty the trash folder often. The limited space includes the space used for trash.
• Quotas apply per drive or per array. If a quota is set to 1 GB, each array or drive can use a maximum of 1 GB.
• Quotas cannot be set for external hard drives connected to the TeraStation and hard drives that are configured as media cartridges.
• If both user and group quotas are configured for a user, the most restrictive quota will always apply.
• Make sure that SMB2 is disabled before using quotas on the TeraStation.
45

Quotas for Users

Follow this procedure to limit the shared folder disk space available for a user.
1 In Settings, click to the right of “Users”.
2 Select the user whose space will be limited.
3 Enable quotas, choose the maximum space the user will be allowed to use, and click OK.
Note: If you change the primary group, restart the TeraStation to apply the quota settings.
4 Click Close.

Quotas for Groups

Follow the procedure below to limit the space for shared folders that each group can use.
1 In Settings, click to the right of “Groups”.
2 Select the group whose space will be limited.
3 Enable quotas, choose the maximum space the group is allowed, and click OK.
4 Click Close.
5 In Settings, click to the right of “Users”.
6 Change the user’s primary group to the group with the quota, then click OK.
7 Click Close.
46

Size Limits

If LVM is enabled, volumes can be created with maximum size limits.
1 In Settings, click Drives.
2 Select LVM.
3 Select the drive or array where the volume will be located and click Enable LVM on Volume.
4 The “Confirm Operation” screen will open. Enter the displayed number, then click OK.
5 Click OK.
6 Click Edit under “NAS Volume”.
7 Click Create Volume.
47
8 Configure the desired settings, then click OK.
9 Click OK.
10 Click Close.
11 Click Close.
12 Navigate to File Sharing - Folder Setup.
13 Click Create Folder.
14 Configure the settings.
48
Notes:
• The name may contain up to 27 alphanumeric characters, hyphens (-), and underscores (_). Do not use a symbol as the first character.
• The description may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do not use a symbol or space as the first character.
• If multi-byte characters are used in a shared folder name used for both AFP and FTP, configure the client language to match the characters that are being used. Also, you may be unable to access the folder if certain characters are used in the name, so the use of letters and numbers only is recommended.
• The names of shared folders used for both AFP and FTP should not use characters from different language sets (such as mixing Japanese and Korean characters, for instance).
15 Select the volume that you created and click OK.

Using the TeraStation as an iSCSI Device

Introduction

iSCSI is a protocol for carrying SCSI commands over IP networks. Unlike traditional SAN protocols such as fibre channel, which requires special-purpose cabling, iSCSI can be run over long distances using existing network infrastructure. Normal Windows formatting such as NTFS is supported.
49
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.
Install the Microsoft iSCSI Software Initiator
Windows XP, Windows Server 2003
Before using iSCSI equipment with Windows XP or Windows Server 2003, download and install the “Microsoft iSCSI Software Initiator”.

Hard Drive Replacement

Hard drives in the TeraStation show a blue status LED during normal operation. When a drive fails, its error LED will glow red.
1 Error LED
Glows red if a drive has failed.
2 LCD Display
This display shows the status, network connections, errors, and other information for the TeraStation. Press the Display button to step through the different information available.
3 Status LEDs
The failed drive’s status LED will be glowing a steady red. A drive with a red status LED is ready to hot-swap.
61
Notes:
• Do not unplug a drive whose status LED is green instead of red. Dismount it first or shut down the TeraStation before swapping a working drive. If you remove the drive without properly dismounting it, data may be lost or the TeraStation may malfunction.
• Use a Buffalo OP-HDS series drive of the same size or larger for the replacement drive. If a larger drive is used, the extra space will not be usable in a RAID array.
• To avoid damaging the TeraStation with static electricity, ground yourself by touching something made of metal before handling any sensitive electronic parts.
• After a drive is replaced, it takes about 30 minutes before normal file reading and writing are restored. Settings may not be accessible during this period.
• Do not change the order of the hard drives in the TeraStation. For example, pulling out drive 1 and replacing it with drive 2 may cause data to be corrupted or lost.
• If the LCD display does not change after a new drive is installed, click Rediscover Disk in Settings.

Chapter 5 Backup

Back Up from the TeraStation

You can back up TeraStation folders to:
• A different folder on the TeraStation
• Another LinkStation on the network
• Another TeraStation on the network
You can also configure backup jobs from Easy Admin.

Preparing a Backup Destination

First, configure a folder as a backup destination.
1 In Settings, navigate to Folder Setup.
2 Choose the folder to set as a backup destination.
3 Click Edit.
4 Check “Backup” from “LAN Protocol Support”, then click OK.
68
Note: To configure a password, enter it in the “Remote Backup Password” field. Leave this field blank if you don’t want a password. If the target device is configured with a backup password, you can easily find the backup target folder during configuration of the backup job by searching for the password.
Backing up to a LinkStation or TeraStation on another network when connected by a VPN
You can back up to a LinkStation or TeraStation on another network as long as the two networks are connected by a VPN. Follow this procedure to enter the IP address or hostname of the target LinkStation or TeraStation.
1 In Settings, click Backup.
2 Click to the right of “Backup”.
3 Click List of LinkStations and TeraStations.
69
4 Click Add, enter the IP address of the target LinkStation or TeraStation, and click Close.
If your setup meets the requirements below, you don’t have to configure these settings:
• The source and target TeraStations are on the same network.
• No backup password is set for the target TeraStation.
• No TeraStation from outside the subnet, or connected by a VPN, is used.
Notes:
• To back up data between LinkStations or TeraStations on a network using jumbo frames, make sure that both de­vices are configured to use identical (or similar) Ethernet frame sizes. If Ethernet frame sizes are significantly dif­ferent, the backup job may not be properly performed. In such a case, select the default frame size (1518 bytes).
• You can also specify hostname by a fully qualified domain name (FQDN).

Configuring a Backup Job

1 In Settings, click Backup.
2 Click to the right of “Backup”.
70
3 Click Create New Job.
Note: Up to 8 backup jobs can be configured.
4 Select backup settings such as date and time to run.
The following types of backup jobs may be selected:
Type Files included Normal backup All files in the source will be backed up to the destination.
The first time the backup job runs like a normal backup. In subsequent
Overwrite (incremental)
Overwrite (differential)
Management backup
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 target folder will be set to read-only. Do not use folders from drives formatted with FAT.
71
5 Click Add.
6 Click Browse under “Backup Source Folder Name”.
7 Select the shared folder that will be the backup source, then click OK.
8 Click Browse under “Backup Target Folder Name”.
9 Select the backup target and click OK.
Note: If you will use the same folder for both Amazon S3 remote replication and as a backup target folder, create a new subfolder under “\wbfs\amazons3”. Under “LAN Protocol Support”, enable “Backup”. Without these settings, that shared folder will not be listed in the backup target folder list.
10 Click OK.
Tasks added to “Backup List” are displayed.
11 Click Close.
72

Replication

Replication copies all data from a share to a share on a different TeraStation. This is an easy way to configure a reliable system to provide data protection in the event your main TeraStation fails. To configure replication, connect an Ethernet cable to the LAN port of each TeraStation and follow the steps below.
1 In Settings, click Backup.
2 Click to the right of “Replication”.
3 Click Edit.
Notes:
• Files that only exist on the replication target are deleted when you click Run Complete Resync.
• Files recently added to the replication source are copied to the replication target when you click Run Differential Resync. Files that are only on the replication target are not deleted.
4 Click Add.
5 Click Browse under “Replication Source”.
6 Select the shared folder that will be the replication source, then click OK.
73
7 Click Browse under “Replication Target”.
8 Select the shared folder that will be the replication target, then click OK.
9 Click OK.
10 Click Yes.
Notes:
• During setup, you may choose to encrypt and/or compress replication data. Encrypted data will transferred securely on the network. Compressed data will ease network loading and is recommended for slow or heavily loaded network connections. Either will increase the CPU load on the source TeraStation. Encrypted and com­pressed data will be unencrypted and decompressed on the target TeraStation.
• A maximum of 64 shared folders can be configured for replication.
• Shared folders with a backup password set cannot be selected as replication targets.
• Replication source data is copied using a differential overwrite to the replication target folder. Note that any data that is not in the replication source will be overwritten.
• 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 replica-
74
tion.
• You can select subfolders as the replication source. Folders whose names contain more than 80 alphanumeric characters cannot be selected.
• If a “Replication I33 ReplicateFailure” error occurs, navigate to Backup - Replication and click Run Complete Resync or Run Differential Resync. “Run Complete Resync” will overwrite all data to the replication target folder but “Run Differential Resync” will only copy data that does not exist at the replication target.
• 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 target folders.

Failover

With failover, two TeraStations are connected to the network for redundancy. If a problem occurs in the main TeraStation so that it can no longer be accessed, operation is automatically switched to the backup TeraStation.
Note: Use identical model and capacity TeraStations for the main TeraStation and backup TeraStation. If the capacity of the main TeraStation is larger than that of the backup TeraStation, a “Replication I33 ReplicateFailure” error will occur.

Ethernet Cable Connection Methods

Two different configurations for failover are available. With the first setup, if the main TeraStation fails, the backup TeraStation will replace it completely, using the same name and IP address. The backup TeraStation is updated over normal network traffic.
Connecting to the network at LAN port 1 and setting failover at LAN port 1
75
With the second setup, the backup TeraStation and main TeraStation are connected by a second Ethernet cable connecting their LAN 2 ports. Updating is done over this dedicated network path, so updates are quicker and don’t interfere with normal network traffic. With this setup, if the main TeraStation fails, the backup TeraStation will replace it by name, but will keep its original IP address.
Connecting to the network at LAN port 1 and setting failover at LAN port 2
The main and backup TeraStations should be the same model and capacity. Use fixed IP addresses for both TeraStations. Because the IP address of the TeraStation designated as the backup cannot be changed, set its IP address before configuring failover.
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 TeraStation and the backup TeraStation. However, the UPS settings of the main TeraStation will not be copied to the backup TeraStation.
If the backup TeraStation is configured to sync with the UPS connected to the main TeraStation, then if the main TeraStation shuts down, the backup TeraStation will no longer be able to detect if there was a power outage. In this case, move the UPS communication cable from the main TeraStation to the backup TeraStation and reconfigure the UPS link settings.

Configuring Failover

1 In Settings, click Backup.
2 Open Failover.
3 Click Edit Failover Status.
4 Select a TeraStation to be the target backup device.
76
5 Enter the administrator password of the target backup device, then click Start Failover.
6 If the administrator password is correct, the backup TeraStation will beep.
7 To accept the settings from the main TeraStation, hold down the function button on the front of the backup
TeraStation until it stops beeping.
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.
• 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 failover TeraStations should be 1518 bytes. To change the Ethernet frame size, navigate to Network - IP Address, click the LAN port and Edit, and change the Ethernet frame size to “1518” bytes.
• Files whose filenames contain more than 80 alphanumeric characters will not be backed up.
• If a “Replication I33 ReplicateFailure” error appears on the LCD display, navigate to Backup - Replication and click Sync.
• Don’t use the same TeraStation for both failover and replication, or failover and Time Machine.
• If “Approve/Deny” window is displayed repeatedly or failover does not start, shut down both the main and backup TeraStations. Turn on the main TeraStation first and let it boot up. Then power up the backup TeraStation. Reconfigure failover.
Maintenance Mode
If failover is configured, change to maintenance mode temporarily before turning off the TeraStation or updating the firmware. Maintenance mode can be enabled and disabled at Backup - Failover in the main TeraStation’s settings.
Service IP Address
The “Service IP Address” will be the new address of the backup TeraStation when it takes over operation from the main TeraStation. If no service IP address is set or a fixed IP address is set, an attempt is made to inherit the IP address set for the main TeraStation.
Network Problems
If network problems occur, the following messages may appear on the TeraStation’s LCD display even though neither TeraStation has failed. If this happens, disable and then reset failover.
• “FailOver I49 LostMainTarget” - This message (I49) is displayed on the LCD panel of the backup TeraStation when operation switches from the main TeraStation to the backup TeraStation.
• “E27: LostBackupTarget” - This message (E27) is displayed on the LCD panel of the main TeraStation if it is no longer able to detect the backup TeraStation on the network.

Notes:
• Install after logging into your computer using an account with administrator rights.
• Install another media player to play recorded videos if the version of Client Tools is 5.7.3.2 or later.
• Install VideoLAN VLC media player 1.11~1.13, or Apple QuickTime 7 or later if the version of Client Tools is older than 5.6.19.3. VLC media player 2.0.x may not work with some network cameras. Using VLC media player is recom­mended if your network camera records MPEG-4 format.
• If VLC media player is installed, use the default installation location (C:\Program Files (x86)\VideoLAN\VLC in Win­dows 7 64-bit or the Application folder in Mac OS).
• If surveillance cameras or client tools installed under C:\Program Files (x86)\BUFFALO\SurveillanceServer\Bin are blocked due to the OS firewall, refer to the OS help for instructions about how to disable the firewall.
• Install Client Tools on one or more computers connected to the same network as the network camera(s) and the TeraStation. Surveillance camera settings are shared for all cameras on the network.

Connecting Devices to the Network

Connect the following devices to the network.
• A TeraStation that supports surveillance cameras
• A compatible network camera
• A computer with the above client tools installed
Notes:
• Connect all devices on the same network subnet.
• Set the TeraStation’s and network camera’s time settings to the correct time. By default, the TeraStation adjusts its clock automatically by using a default NTP server. This NTP server belongs to Internet Multi Feed Inc. For more information, visit www.jst.mfeed.ad.jp.
• To select a different NTP server, click Name/Time/Language from Management. Click Time, then Edit. Uncheck “Use Default NTP Server” and enter a new NTP IP address. Click OK.
• If NTP is not used, disable it and enter the time and date manually. Click Use Local Date/Time to import the time and date from your computer.
In certain cases, the DNS server address must be set in order to access the NTP server.
• Use the dedicated utility provided with the network camera or other program to confirm that the network cam­era operates properly.
