Note: The Web Admin interface is compatible with Internet Explorer 9 or later, Firefox 8 or later, Google Chrome 15 or later, and Safari 5 or later. 9 Change the administrator password in the displayed screen. Note: The default username and password are "admin" and "password" respectively. 10 Click [Management] - next to [Name/Time/Language] - [Time] - [Edit], then configure the TeraStation's clock with the Web Admin interface. Notes: • By default, the TeraStation adjusts its clock automatically by using an NTP server. The internal clocks of the TeraStation and other devices on your network may run at slightly different speeds. Over a long period of time your network devices may show somewhat different times, which can cause network problems. If clocks on your network vary by more than 5 minutes it may cause unexpected behavior. For best results, keep all clocks on the network set to the same time by adjusting them regularly, or use an NTP server to correct them all automatically. • NTP may not be usable in some networks. The default NTP Server (ntp.jst.mfeed.ad.jp) belongs to Internet Multi Feed Inc. For more information, please visit www.jst.mfeed.ad.jp. Use NTP at your own risk. Buffalo Technology is not responsible for any loss or damage caused by using of this service, stopping the service, or missing service. • If the TeraStation cannot automatically obtain the time from an NTP server, check the TeraStation's DNS server address settings. If the NTP server is specified by a hostname instead of an IP address, a DNS server address 12 must be set in [Network] - [IP Address] of the Web Admin interface. 11 To configure a RAID scan, click [Drives], then change the icon next to [RAID Scanning] from -> . Note: RAID scans check RAID arrays to confirm that they can be read properly and have no bad sectors. If any problems are found, they will be repaired automatically. 12 This creates a USB memory device that can be used to restore default settings or transfer settings to another identical TeraStation. 1. In the TeraStation's Web Admin interface, click [Management] - next to [Restore/Erase]. 2. Connect a USB memory device (not included) with 1 GB or larger to a USB 2.0 port on the TeraStation. 3. Select [Create a special USB drive for password recovery]. This recovery USB drive will also reset the TeraStation's administrator password to its default. 4. Select the connected USB memory device, then click [Execute]. To return the TeraStation to the default settings using the created USB memory device, see "Recovering by Changing the Boot Mode Switch on the Rear Panel When Starting the TeraStation" in Chapter 9. 13 In NAS Navigator2, double-click your TeraStation's icon. This will open the shared folder of the TeraStation. Notes: • For Mac OS X, the TeraStation is mounted as a drive icon on the desktop, or it is displayed in the sidebar of the 13 Finder. • You can now use the TeraStation's shared folder to save files just like any other folder. This completes the setup. Turning on the TeraStation Press the power button on the TeraStation to turn it on. Turning off the TeraStation The TeraStation might be damaged if it is unplugged suddenly without powering it down properly first.

This completes the opening of the Easy setup screen in the Web Admin interface. 21 Chapter 3 Access Restrictions You may restrict access to specific shared folders. Only selected users and groups will be able to access these folders. Notes: • Access restrictions can be set separately for each shared folder. However, access restrictions cannot be set for folders within the shared folder. • Access restrictions must be configured through the TeraStation's Web Admin interface. Standard Windows access restrictions as set in the Security tab of the Properties window of the TeraStation folder are not supported and may cause unexpected behavior. • Instead of the procedure below, you can also configure users, groups, and shared folders from Easy Setup by clicking [Access Restrictions]. Configuring Access Restrictions on Users and Groups Adding a Shared Folder 1 In the TeraStation's Web Admin interface, click 2 Click [Create Folder]. next to [Folder Setup]. 22 3 Configure the desired settings, then click [OK]. 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 bytes alphanumeric characters, hyphens (-), underscores (_), and spaces. Do not use a symbol and space as the first character. • You may create up to 400 shared folders on the TeraStation. • If multi-byte characters are used in a shared folder name used for both AFP and FTP, the client language must be set by clicking [Management] next to [Name/Time/Language] - [Language] - [Edit] 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, and so the use of letters and numbers only is recommended. • The names of shared folders used for both AFP and FTP cannot use characters from different language sets (such as by mixing Japanese and Korean characters, for instance). You have created a new shared folder. Preventing accidental deletion of data To protect your data from accidental deletion, you may enable a Recycle Bin for each shared folder. Only SMB connec23 tions can use a Recycle Bin. If the Recycle Bin is enabled, data that is deleted from the shared folder is temporarily moved to the Recycle Bin folder. To restore the deleted data, open the Recycle Bin folder and move the files back to the share. After the Recycle Bin is enabled, the Recycle Bin folder is created when a file or folder is deleted from the shared folder. The Recycle Bin folder is not created immediately after it is enabled. To delete all the files in the Recycle Bin, click [File Sharing] - [Folder Setup] - [Empty the recycle bin] in the Web Admin interface. To set a shared folder to Read-Only In the Shared Folders settings window, select Read-Only for the [Shared Folder Attributes], then click [Apply]. The default setting is [Read & Write]. Data in a shared folder that is set to Read-Only can be written only by users and groups with write access. Read-Only shared folders and HFS+ formatted USB hard drives will have "(Read Only)" added to the shared folder description. To create a shared folder accessible only to users who know that it exists To hide a shared folder, select the folder attribute [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. FTP, SFTP, and Mac AFP folders cannot be hidden. Restrictions The restrictions described here assume that the latest firmware version is installed in the TeraStation. The latest firmware can be downloaded from the Buffalo Technology web site. • The following characters are handled differently by Mac OS X and Windows. Avoid using these characters when sharing data between Mac OS X and Windows: • • Windows does not support some characters that Mac OS X 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 Mac 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 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) If any of the characters below are used for the shared folder name, workgroup name, or filename, the data on the TeraStation may not be accessible or file operations may not be performed properly. To prevent this from happening, avoid use of these characters.-
24
•
File and folder names may contain up to 255 single-byte characters (UTF-8). DBCS characters (such as Japanese) count as two characters (2 bytes) each. File and folder names should contain 255 bytes of data or less. You may not be able to copy a folder or file whose name contains more than 255 bytes of information.
•
Attributes (hidden/read-only) for the folders and files in the TeraStation cannot be set in Windows. Use the Web Admin interface to set attributes for shared folders. In the Web Admin interface, navigate to [File Sharing] - [Shared Folder]. Select [Read Only] or [Read & Write] from the attributes.
•
If non-Roman alphabetical folder names or workgroup names do not display properly, rename the folder or workgroup with Roman alphabetical characters.
•
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 from Mac OS X 10.3.9, the names of mounted volumes may appear as unreadable characters in Finder or other applications. (This is not a problem with the filename or data.)
•
In Mac OS X 10.5 to 10.5.6, if a search is conducted using Spotlight, the search cannot be performed over an AFP connection. In this case, either use an SMB connection, or use Mac OS X 10.5.7 or later.
•
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.
•
The value for the hard drive capacity when checked from a browser may differ from the value shown when checked from the Properties window of the hard drive in Windows.
•
During a file transfer, if settings are changed in the Web Admin interface, the file transfer operation may be aborted.
•
File copying to the TeraStation is protected by a journaling file system, but the situations below can occur if the copying operation is canceled or ended (such as by disconnection of a Ethernet cable or power outage) while in progress. - 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. Even if the TeraStation's hard drive is formatted, the [% Used] and [Amount Used] in the Web Admin interface will not be 0. This is because some drive space is being used for the system area.
•
Your TeraStation 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.
•
To delete the contents of the trashbox folders for all shared folders, click [File Sharing] - [Folder Setup] - [Empty the recycle bin] in the Web Admin interface.
•
Do not set the same network address for LAN port 1 and LAN port 2. Network communication may be unstable if the IP addresses are set so that they have the same network address. 25
•
Use LAN port 1 to access different network subnets from the TeraStation. Access to a different network subnet is not possible from LAN port 2 since it doesn't have a default gateway. Examples: - Email notification isn't working because the mail server can't be found. - A backup device isn't detected, even when the IP address is specified and the backup location is selected. To prevent these and similar problems, either use LAN port 1 on the TeraStation for main network communication, or move other devices such as a mail server or backup device to the same subnet of the network.
Adding Users 1
In the TeraStation's Web Admin interface, click
2
Click [Create User].

Enter the desired settings, then click [OK].
next to [Users].
Notes: • Usernames may contain up to 20 alphanumeric characters, hyphens (-), underscores (_), periods (.), !, #, &, @, $, *, ^, and %. Do not use a symbol as the first character. • If the user ID is left blank, a user ID will be automatically assigned. Use numbers between 1000 and 1999 to set a user ID manually. Make sure that user IDs are unique. • To assign quotas for users, enable user quotas and enter a limit in GB. • If you log in with a username, you can check the TeraStation name, IP address, workgroup, and drive status, and 26
• • • •
•
you can change your own password. User descriptions may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do not use a symbol and space as the first character. When setting users with access privileges, a maximum of 300 users 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. In Windows 7/Vista/XP/2000 and Windows Server 2003/Server 2008, if the network login name is different, a screen is displayed for entering the username and password, but even after these are entered, access to the shared folder is not possible. For best results, use the same username and password for both Windows and the TeraStation. Repetitive deletions and additions of users may cause quotas to not work properly. Even if data is copied by a backup job, quotas may not work properly if a user ID or group ID is duplicated. Always use distinct, unique usernames and group names.
This completes the procedure for adding users.
Quotas only limit available space. They don't check the amount of space that each user is using, so these amounts must be managed individually. Owners can be confirmed with the procedure below. •
From the Properties screen of the file or folder, open a new window from the [Security] tab - click [Advanced], and check using the [Owner] tab.
•
In My Computer or Explorer, right-clicking the bar shown for [Name], [Date modified], [Type], [Size], or other parameter allows the selection of which parameter details are displayed. [Owner] can be confirmed from the right-click menu. The procedure for confirming the owner varies depending on the OS. The above example is for Windows XP.
Importing user information All user information can be imported in a single operation by entering the information below to [CSV Files] in the [File Sharing]-[Users] screen and clicking [Import CSV File]. User information format: Username (required), password (required), and user description (optional). Example: username1,password1,comment1 username2,password2,comment2 username3,password3,comment3 … … … • Importing may take over an hour depending on how many users are imported. During import, other operations performed from the Web Admin interface may be slower than usual, or may not be performed at all. •
Commas (,) are used as separators. Do not put spaces before or after commas.
•
If a line has an incorrect format, the user for that line will not be registered.
•
If a user with the same name is already registered, the new user information overwrites the old information.
•
Do not use commas (,) in the username, password, or user description. See the previous page for other restrictions on what characters to use for the username, password and user description.

Notes: • If the Group ID field is left blank, a group ID will be automatically assigned. Use numbers between 1000 and 1999 to set a group ID manually. Make sure that group IDs are not duplicated by other groups. • To set a Quota for a group, enable group quota and enter the maximum disk space allotted in GB. • 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 and space as the first character. • You may register up to 300 groups with the TeraStation. • Repetitive deletions and additions of groups may cause quotas to not work properly. Even if data is copied by a backup job, quotas may not work properly if a user ID or group ID is duplicated. Always use distinct, unique usernames and group names. This completes the procedure for adding groups.

Access Restrictions on Active Directory The TeraStation can join an Active Directory domain as described below. Notes on centralized management of multiple TeraStation accounts • The TeraStation can link to Active Directory. In an Active Directory environment, the TeraStation uses account information from the Active Directory server to set access restrictions for files and folders on the TeraStation. There is no need to perform individual account management for the TeraStation. If multiple TeraStations are installed on the network, all accounts are centrally managed in the Active Directory, greatly reducing the operations required for installation and management. • A maximum of 1000 domain users and 1000 groups can be downloaded from Active Directory. • If usernames or group names from Active Directory include multi-byte characters, you will not be able to configure access restrictions for them. • This section shows the procedure when using Active Directory with Windows 2000 Server, Server 2003, and Server 2008. • For certain security settings, it may not be possible to participate in the domain, or even if participation is possible, authentication may not be possible. If this happens, set access restrictions for users and groups using the authentication server.

Restrictions The restrictions described here assume that the latest firmware version is installed in the TeraStation. The latest firmware can be downloaded from the Buffalo Technology web site. • When you have the TeraStation joined to an Active Directory domain, you must specify the DNS Server which can resolve names for Active Directory domain. •
After building an Active Directory domain, the administrator's password which is needed to join the Active Directory domain must be changed at least once, or joining the Active Directory domain will fail.
•
Active Directory domain's DNS name and NetBIOS name must be identical.
•
If there are more than 5 minutes differences between the TeraStation's clock and the domain controller's clock, joining the domain or authenticating domain user or group may fail.
Access Restrictions on an NT Domain The TeraStation can join an NT domain as described below. 32
Notes on centralized management of multiple TeraStation accounts • The TeraStation can link to an NT domain. In an NT domain environment, the TeraStation uses account information from the NT domain server to set access restrictions for files and folders on the TeraStation. There's no need to perform individual account management for the TeraStation. If multiple TeraStations are installed on the network, the account information is centrally managed in the NT domain, greatly reducing the operations required for installation and management. • In some environments, it is not possible to log on using an NT domain. If this happens, use an Active Directory domain. • A maximum of 1000 domain users and 1000 groups can be downloaded from an NT domain server.

Chapter 4 Managing your Storage
RAID Arrays The default RAID mode of your TeraStation is different for different models as shown below. TeraStation TS5800D TS5600D
Modes RAID 6
TS5400D
RAID 5
TS5200D
RAID 1
Notes: • If you change the RAID mode, all data on the array is deleted. Always back up any important data before changing the RAID mode. • In this document, "recovery" means putting the TeraStation back to the state it was in before the malfunction happened. It does not mean reading data from failed hard drives. • While the RAID array is building, the message "RAID I17 ARRAYx Resyncing" is displayed on the LCD panel and file transfers will be slower than normal. The characteristics of each type of RAID are described below. Some of the RAID modes listed below may not be available if your TeraStation doesn't have the required number of drives for the RAID mode.
RAID 6 (*1) 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 will be the sum of 2 drives' capacity. If 2 hard drives in the array are damaged, you can recover data by replacing them. If 3 or more drives are damaged, your data is lost.
RAID 61 (*3) RAID 61 arrays are available for TeraStations with 8 hard drives. RAID 61 combines 8 drives into a single array. In this mode, two RAID 6 arrays are mirrored in a RAID 1 array. 8 drives in a RAID 61 array will have a usable capacity of 2 x the capacity of the smallest drive.
RAID 60 (*3) RAID 60 arrays are available for TeraStations with 8 hard drives. 8 drives are combined into a single array. In this mode, two RAID 6 arrays are combined in a RAID 0 array. 8 drives in a RAID 60 array will have a usable capacity of 4 x the capacity of the smallest drive.
39
RAID 5 (*1) RAID 5 arrays are available for TeraStations with 4 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. If 3 hard drives are combined into a RAID 5 array, the usable space is the sum of 2 hard 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 51 (*2) RAID 51 arrays are available for TeraStations with 6 or more hard drives. RAID 51 combines 6 or 8 hard drives into a single array. In this mode, two RAID 5 arrays are combined into a RAID 1 array. The total usable space for 6 drives in a RAID 51 array is 2 x the capacity of the smallest drive. For 8 drives, the total usable capacity is 3 x the capacity of the smallest drive.
RAID 50 (*2) RAID 50 arrays are available for TeraStations with 6 or more hard drives. RAID 50 combines 6 or 8 drives into a single array. In this mode, two RAID 5 arrays are combined into a RAID 0 array. The total usable space for 6 drives in a RAID 50 array is equal to 4 x the capacity of the smallest drive. For 8 drives, the total usable space is equal to 6 x the capacity of the smallest drive.
RAID 10 (*1) 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 ÷ 2.
RAID 1 Combines 2 or more hard 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 any one drive in the array remains undamaged, all data in the array can be recovered.
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.
Normal mode This mode uses the hard drives inside the TeraStation as individual hard disks. It is sometimes referred to as JBOD. The disk space you can use is the total capacity of all hard drives in the TeraStation. If any drive is damaged, then the data on that drive is lost. (*1) Available for TS5800D, TS5600D, TS5400D series TeraStations. (*2) Available for TS5800D, TS5600D series TeraStations. (*3) Available for TS5800D series TeraStations.

If you turn it off, the RAID check will start over. • The "Confirm Operation" screen will open. Enter the displayed number, then click [OK]. • Instead of the procedure above, you can also configure RAID settings from Easy Setup.
You have now set up a RAID array. Next, create a shared folder. 42
Configuring a Hot Spare If one drive in an array fails and a hot spare is configured, the TeraStation will switch over to the hot spare immediately. You can configure a hot spare if the following condition are met: • There is an extra drive not used in an array. •
You have a RAID 6, RAID 5, RAID 51, RAID 50, RAID 10, or RAID 1 array. Notes: • All data on the hot spare drive will be deleted when it is configured as a hot spare and again when it changes over from a spare to a drive in the array. • A hot spare cannot be configured for TeraStation models with only two hard drives.

RMM (RAID Mode Manager) With RMM, you can create or expand a RAID array without erasing the data on the drives. Changing from normal mode to RAID 1: Hard drives that aren't in a RAID array will show [Normal (RMM available)]. You must have at least two drives available (not in a RAID array) to change from normal mode to a RAID 1 array with RMM. Adding a drive to an existing RAID array: You can add a drive to a RAID 1, RAID 10, RAID 5, RAID 51, RAID 50, or RAID 6 array. Drives that can be added to the RAID array will show [Normal (RMM available)] or [Normal]. Notes: • Each drive should have the same capacity. • RMM can be used to expand only one hard drive per operation. To expand by two or more drives, RMM must be performed several times.

Adding an External Hard Drive
Connect an External Drive Your TeraStation includes USB ports. You can connect Buffalo external drives to them. They will appear as an additional shared folders on the TeraStation. Refer to chapter 11 for the position of the USB ports. Formatted drives will be detected automatically. Drives that are not formatted should be formatted from the Web Admin interface. Notes: • If the TeraStation is powered on, dismount any USB drives before unplugging them. If the TeraStation is off, then 46
all USB devices are already dismounted and you can remove them safely. • If a USB drive is unplugged without being dismounted first, it may not be recognized properly when it is reconnected. If this happens, restart the TeraStation and then reconnect the drive. • Hubs are not supported. Only connect a single USB drive to each USB port. • Backup data from Mac OS X may include characters that cannot be written to FAT16 or FAT32 drives such as ".DS_Store". For best results, reformat the drive before using as a backup target. After a USB drive is recognized, Windows will add "usbdisk X" under the TeraStation in Network, where "X" is the USB port where the hard drive is connected.
Formatting External Drives Formatted drives are detected automatically. If a drive is not formatted, format it from the Web Admin interface. Refer to "Formatting Hard Drives" for the procedure.
Notes: • A format deletes all data from a hard drive. Be careful! Back up any important data on a drive before formatting it. • If a drive is formatted, all partitions on the drive are also erased. • Shared folders cannot be accessed during formatting. • Do not turn off or disconnect power to the TeraStation while formatting a hard drive. • A format may take anywhere from a few minutes to several hours depending on the size of your drives.
Access Restrictions on External Drives You can set access restrictions on the new drive. Refer to "Configuring Access Restrictions" in chapter 3 to set the access restrictions. Note: Even if a shared folder is not visible, you can still format the drive, run a disk check, and back up to the new drive.
Removing Hard Drives If the TeraStation is powered on, dismount the external hard drive before unplugging it. You may dismount drives with the function button, or from within the Web Admin interface. If the TeraStation is off, then the USB device is already dismounted, and you can remove it safely. 47
Dismounting with the Function Button If the TeraStation is on, hold down the function button for 7 seconds to dismount the USB drive. The blue LED will go out when the drive is dismounted. You may now unplug it safely, even after the blue LED comes back on. If the TeraStation is off, then the USB device is already dismounted, and you can remove it safely. Notes: • Refer to chapter 11 for the positions of the USB ports and the function button. • Wait 3 minutes before reconnecting a dismounted USB drive. It may not be recognized if you attempt to connect it immediately.

This completes the drive formatting procedure.
Encrypting Drives If encryption is selected during a reformat of a drive or array, it will be encrypted with 128 bit AES. The drive or array will then be only readable from that specific TeraStation. To unencrypt the hard drive, uncheck [Encryption] and format it again. For more information, refer to "Formatting Hard Drives".
Notes: • Formatting deletes all data from a hard drive. Be careful! Back up any important data on a drive before formatting it. • Performance will be slower if an array or drive is encrypted. • USB drives cannot be encrypted. • Shared folders cannot be accessed during formatting. • Do not turn off the TeraStation until formatting is complete.
Media Cartridge System The Media Cartridge System enables you to use an internal hard drive as a removable storage device in the same way as an external hard drive. The Media Cartridge System can be used for removing the internal hard drive and connecting it to another TeraStation with the data intact. To return a drive to its original state, uncheck "Media Cartridge" and reformat the hard drive
52
For more information, refer to "Formatting Hard Drives".
Notes: • Formatting deletes all data from a hard drive. Be careful! Back up any important data on a drive before formatting it. • Hard drives that are converted to a media cartridge do not support changing RAID modes, creating LVM volume, or access restrictions. • Hard drives that are converted to a media cartridge do not support connection to a computer for reading. • Shared folders cannot be accessed during formatting. • Do not turn off the TeraStation until formatting is complete.
Erase Data on the TeraStation Completely Under some circumstances, data from a formatted drive can be recovered. To ensure that data is gone forever, follow the procedure below to completely erase the data.

The "Confirm Operation" screen will open. Enter the displayed number, then click [OK].
Follow the instructions on the screen. Notes: • Under some circumstances, data from a drive that has been formatted normally can be recovered. The disk erasure process in this section does a much more thorough job of erasing data than a normal format. 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 drive will be completely erased. The TeraStation shuts down automatically after the complete format is finished. After a complete format is performed, the TeraStation is in the following state: - All drives in normal 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.
This completes disk erasure.
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 maximum of 1 GB. • Quotas can not be set for external hard drives connected to the TeraStation and hard drives that are converted to a media cartridge , only internal drives.

Using the TeraStation as an iSCSI Device
Introduction What is iSCSI? iSCSI is an abbreviation for Internal Small Computer Systems Interface, which is a standard that capsulizes SCSI commands using TCP/IP protocol for enabling data transmission over the network (LAN). If connecting by Ethernet (LAN cable) using iSCSI, the TeraStation is recognized as a computer or server local disk. Enables installation at any location: The TeraStation is recognized as a local disk in the same way as external hard drives, but because it uses a network connection, the TeraStation does not need to be placed near the computer or server where it is used like external hard drives. Enables usage as a local drive: Because the TeraStation is recognized as a local drive, OS standard functions and applications can be used without any changes. (The NTFS format system from Windows can also be used.) Because the data transmission system varies when used as NAS, some applications may not be supported.
Differences Between NAS and iSCSI iSCSI usage procedure: The server creates shared folders in the iSCSI-connected drive, and the computer accesses the shared folders of the server. • The TeraStation can be used as a local drive from Windows Server. (Access from the client is performed by passing through the server.) •
Access restriction functions such as ActiveDirectory available in Windows Server can be used without any changes.
•
Because access is performed in block units, usage is also possible by software such as databases that are dependant on the format system.
NAS usage procedure: Both the server and computer directly access the shared folders in the NAS. • Shared folders can be easily created and used (separate server is not needed) •
Direct access from the client is possible in file units (unique format system is used (XFS))
•
Support for automatic backups using self-backup function
Examination of Network Configuration The use of a Gigabit (1000BASE-T) environment is recommended when using an iSCSI hard drive. As much as possible, please consider installing a Gigabit network environment for making the connections. (Maximum performance cannot be realized in a 100BASE-TX network environment because the line transfer rates are slow.) The transfer rates also significantly affect network traffic. It is recommended that the connections with the TeraStation use a dedicated network (iSCSI network) that is separate from the network adapters used for the regular LAN.

Hard Drive Replacement Procedure When a hard drive in the TeraStation has failed, replace the failed hard drive as described below. Hard drives in the TeraStation show a blue status LED during normal operation. When a hard drive in the TeraStation fails, its Error LED will glow red. Open the front cover and check the Status LEDs. The malfunctioning drive's Status LED will be
79
glowing or flashing red.
1.
Error LED
Glowing red: A hard drive in the TeraStation fails.
2.
Status LED
Flashing red: If you need to remove a drive whose Status LED is flashing red, either shut down the TeraStation, or dismount the drive in the Web Admin interface. Once the TeraStation is shut down, or the drive is dismounted, then it is safe to replace the drive. Glowing red: The malfunctioning drive's Status LED will be glowing red. This drive may be hot-swapped.
Notes: •
Do not unplug a drive whose status LED is not lit red. If you remove the drive without properly dismounting it, data may be lost or the TeraStation may malfunction.
•
When changing drives, the replacement drive should be a Buffalo OP-HDS series drive of the same size.
•
The TeraStation is fragile. Handle it with care. Do not drop or bump the TeraStation.
•
Use caution when handling the unit in order to avoid personal injury.
•
Never disassemble any parts while you are replacing a hard drive unless instructed to do so in this manual. Any malfunction or damage caused by disassembling the TeraStation will void your warranty.
•
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 is restored. The Web Admin interface may not be accessible during this period either.
•
After a hard drive dismounted from the Web Admin interface is removed, its Status LED will be lit green. 80
•
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 panel does not change even though a hard drive was installed, click [Rediscover Disk] in the Web Admin interface, then perform the RAID rebuilding, format, or other process.
•
In the TeraStation's messages on the LCD panel, "Diskx" is hard drive # X and "RAID ARRAYx" is RAID array # X.
•
The Status LED of a drive configured as a hot spare will be lit green. This drive may be removed.
•
If a drive fails while changing to RAID 1 with RMM trying to preserve data, the data transfer may lock up. If this happens, remove both drives and restart the TeraStation. With the power on, mount the drives and format from the Web Admin interface. All data on the drives will be lost.

All of the settings for the shared folders (such as access restrictions) will be erased after replacing a drive from a RAID 0 array. Create a shared folder before use. For Normal Mode When the replacement hard drive is recognized, the status LED will flash red and the message "Press FuncSW I31 New Disk x ready" will be displayed on the LCD panel. Hold down the function button on the front of the TeraStation for 3 seconds until it beeps. The drive will be formatted as a normal hard drive. If this drive is removed from the TeraStation, all shared folder settings (such as access restrictions) will be lost. Create a shared folder on the drive before use. You have now completed the hard drive replacement process.
85
Drive Replacement (using a redundant RAID mode such as RAID 1, 5, or 6 with a hot spare configured) If your TeraStation's drives are in a redundant RAID mode, and you have a hot spare enabled, a malfunctioning drive in the array is replaced by the spare disk and the RAID array is rebuilt automatically. The Status LED will continue to glow red for the failed drive even after the RAID array is rebuilt with the hot spare. This section describes the replacement process for a hard drive while the TeraStation is still on.

To use the replacement disk as a normal drive rather than a hot spare, navigate to [Drives] - [RAID] and click the RAID array in the TeraStation's Web Admin interface, select the new drive, and click [Set as a normal disk].
You have now completed the hard drive replacement process.
Replacing a non-malfunctioning hard drive Do not replace a hard drive which is not malfunctioning (unless it has been converted to a media cartridge). • If you are operating in RAID 0 mode, all data on that RAID array will be deleted after performing this procedure. You will not be able to use the TeraStation until you reformat the hard drive. •
If you are operating in normal mode, all data on that hard drive will be deleted after performing this procedure. You will not be able to use the TeraStation until you reformat the hard drive.
•
If you must change a drive that is not malfunctioning, either dismount it in the TeraStation's Web Admin interface or shut down the TeraStation before replacing the drive. Then rebuild the RAID array if you are in a redundant RAID mode such as RAID 1, 5, or 6. If you are using RAID 0, delete the RAID array. If you are using normal mode, format the hard drive.
•
If you are using a redundant RAID mode such as RAID 1, 5, or 6, the RAID array will be in degraded mode after performing this operation. You will not be able to use the TeraStation until you rebuild the RAID array.
•
If you remove more than one drive at the same time, all data on the RAID array will be lost regardless of which RAID mode the TeraStation is in. To preserve your data, replace drives one at a time, rebuilding the RAID array after each replacement.

Configuring a Backup Job 1
In the TeraStation's Web Admin interface, click [Backup].
2
Click
3
Click [Create New Job].
next to [Backup].
Note: Up to 8 backup jobs can be configured.
4
Select backup settings such as date and time to run.
Note: The following types of backup job may be selected: 92
• [Normal Backup]: All files in the source will be backed up to the destination. • [Overwrite Backup (Append Backup)]: The first time the backup job runs is just like a normal backup. Each additional time the backup job runs, if file A was added to and file B removed from the backup source, then file A is added to but file B is not removed from the backup destination. Over time, the backup destination folder will become larger than the backup source folder. • [Overwrite Backup (Differential Backup)]: The first time the backup job runs is just like a normal backup. Each additional time the backup job runs, if file A was added to and file B removed from the backup source, then file A is added to and file B is removed from the backup destination. The backup destination folder is always the same as the backup source folder. • [Management Backup]: Each time a backup is executed, management information is stored, and only files that have changed are copied or deleted. Data is retrieved from the previous backup file for files that were not changed (if the previous backup file was corrupted, the file can no longer be referenced). This is used for making backups with limited space or for referencing status at a particular point in time (for use for data snapshot applications). You may select how many generations of data are saved from Unlimited or 1 to 10. - [Management Backup] supports saving backups to destination folders on the TeraStation and connected external hard drives. - Backing up to a external hard drive changes the specified shared folders and shared folders on the external hard drive to read-only. - FAT formatted external hard drives are not supported for Management Backup destinations. - When performing an incremental backup to an external drive formatted with NTFS, if the TeraStation is restarted or disconnected from the drive, the data saved to the drive may suddenly become twice its normal size. Reformatting all backup drives with EXT3 or XFS is highly recommended. - If you back up data to an external hard drive with [Management Backup], do not connect the external hard drive to another device and edit the data. Important backup files could be overwritten.

Restrictions The restrictions described here assume that the latest firmware version is installed in the TeraStation. The latest firmware can be downloaded from the Buffalo Technology web site. • You can register up to the second level of subfolders. However, folders with more than 80 bytes in their names cannot be selected. •
Before they can be selected as backup target folders, folders on other LinkStations or TeraStations must be configured as backup destinations.
•
For best results, TeraStation hard drives should be formatted with XFS or EXT3, including USB-attached drives and drives that are configured as media cartridges. If a drive is instead formatted with FAT32 or FAT16, the following limitations may apply. Files larger than 2 GB cannot be backed up to a FAT16 drive, and files larger than 4 GB cannot be backed up to a FAT32 drive. Errors may occur and backup jobs may stop before finishing. If the second of the date when a file was created is an odd number, overwrite-differential backups may overwrite FAT32 drives even if there is no difference in the data.
•
If the data being backed up contains files from Mac OS X such as ".DS_Store", the file names may include characters that cannot be written to FAT16 or FAT32 drives. This will cause errors and the backup operation may stop before finishing.
•
Note the following if using Auto Power Mode during backups. If the TeraStation is in standby mode, it will power on automatically 15 minutes before a backup starts. If the TeraStation is switched to standby mode immediately before a scheduled backup, the backup may not be performed.
•
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 of these are significantly different, the backup job may not be properly performed. In such a case, select the default frame size (1518 bytes).
•
Backing up files or folders with multi-byte characters in their names may cause log files to output incorrectly. 94
•
If you change RAID settings or reformat a drive, you must redo all backup settings for the drive. If another TeraStation tries to use the drive as a backup destination without redoing the backup job, an error message will be displayed.
•
If the firmware for the backup source and backup target is not the latest version, in certain cases, shared folders with folder names that are 20 bytes or more cannot be selected. You can download the latest version of the firmware for your TeraStation from www.buffalotech.com. This can sometimes fix this problem.
Using TeraStation Batch Backup Batch backup allows backup of shared folders from multiple TeraStations to a single TeraStation. Configure this as described in step 4 on "Preparing a Backup Location". To configure a TeraStation to be the backup destination, make the settings as described on "Preparing a Backup Location" and "Configuring a Backup Job". Note: In the cases below, a TeraStation cannot be selected as the backup source as described in step 8 on "Configuring a Backup Job". If this happens, change the settings as described on "Entering the Password of Other Target LinkStations or TeraStations". • If a password is set for a TeraStation that is a backup source. • If the source TeraStation and destination TeraStation for backup are not on the same subnet.
Replication Replication copies all data from a TeraStation to another TeraStation. It provides an easy way to configure a reliable system that provides data protection in the event that your main TeraStation fails. To configure replication, connect a spare TeraStation to the main TeraStation using an Ethernet cable to connect LAN port of each TeraStation together.

Notes: • Only the shared folders of TeraStation models that support replication can be selected. For details on supported models, see www.buffalotech.com. • Replication can be specified for individual folders. A maximum of 64 shared folders can be specified. • Before replication, refer to "Preparing a Backup Location". Under [LAN Protocol Support], check [Backup] for the target folder 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. Please note that any data that is not in the replication source will be overwritten.
13 Click [OK]. 14 Click [Yes]. You can now configure Replication.
Restrictions The restrictions described here assume that the latest firmware version is installed in the TeraStation. The latest firmware can be downloaded from the Buffalo Technology web site. • Only data written by SMB and CIFS (Windows) and AFP, NFS, SFTP, FTP, and FTPS (Apple) can be mirrored by replication. •
Replication transfers files asynchronously. It may take time to transfer files depending on the network environment or status of the TeraStation.
•
Replication will retry file transfers if they fail due to a temporary disconnection in the network. If the retry fails, an error will occur. The error LED on the front of the TeraStation will glow red and an alarm will sound. To repair, fix the network problem, then navigate to [Backup] next to [Replication] - [Resync] in the Web Admin interface.
•
Click [Resync] to reset the number of unreplicated data files (files that are not backed up to the replication target) to 0. System performance may become slow when accessing a folder that was set as the replication source.
•
Do not set multiple replication targets for one replication source. Multiple transfer processes for replication will run, and system performance will be adversely affected.
•
A large number of files cannot be continuously written to the replication source folder over a long period of time. 97
•
Do not replicate a share that is the target of Time Machine backups by Mac OS X.
•
Cascade settings are not possible in replication. In other words, usage is not possible where files transferred to the replication target are further replicated to another location.
•
System performance may be degraded if Mac OS X writes to the replication source folder with an AFP connection. If this occurs, connect via SMB for better performance.
•
For best results, drives connected to the TeraStation should be formatted with XFS or EXT3. If a drive is instead formatted with FAT32 or FAT16, the following limitations may apply. Files larger than 2 GB cannot be backed up to a FAT16 drive, and files larger than 4 GB cannot be backed up to a FAT32 drive. Errors may occur and backup jobs may stop before finishing. If the second of the date when a file was created is an odd number, overwrite-differential backups may overwrite FAT32 drives even if there is no difference in the data.
•
If the data being backed up contains files from Mac OS X such as ".DS_Store", the file names may include characters that cannot be written to FAT16 or FAT32 drives. This will cause errors and the replication may stop before finishing.
•
If NFS is used in kernel mode, files or folders written by NFS are not transmitted to the replication destination. To change NFS from kernel mode to user mode, select [File Sharing] next to [NFS] - [Edit] in the Web Admin interface.
•
If the firmware for the replication source and replication target is not the latest version, in certain cases, shared folders with folder names that are 20 bytes or more cannot be selected. You can download the latest version of the firmware for your TeraStation from www.buffalotech.com. This can sometimes fix this problem.
Replication Folders Folders that can be selected as the source and destination for replication are described below. Folders that can be selected as the replication sources: • Shared folders on the TeraStation from which replication is configured (except for the "info" folder). This includes USB drives. Folders that can be selected as destinations for replication: • Shared folders on the TeraStation where the replication job is configured (except for the "info" folder). This includes USB drives.*1 •

Failover If your system configuration includes another TeraStation, failover can be set to automatically copy files from the failover source TeraStation (main TeraStation) to the failover target TeraStation (backup TeraStation) so that the main TeraStation and backup TeraStation have the same folder configuration (there may be a time lag in data synchronization due to the time it takes to write data to the backup TeraStation). If a problem occurs in the main TeraStation so that it can no longer be accessed, operation is automatically switched to
98
the backup TeraStation.
Conditions for determining when the main TeraStation has failed: When the backup TeraStation is unable to detect the main TeraStation for a certain amount of time By default, the backup TeraStation attempts to detect the main TeraStation at 60-second intervals. If it is unable to detect the main TeraStation after five consecutive attempts, the main TeraStation is determined to have failed. To change the settings, click [Advanced Settings] and change the setting in the displayed screen. Even if the main TeraStation has not failed, if the backup TeraStation is unable detect the main TeraStation for five consecutive attempts due to a network problem, this is determined to be a failure, and operation will switch to the backup TeraStation. If this happens, failover must be reconfigured in the original main TeraStation. When one of the following errors occurs in the main TeraStation • E12 Cooling Error •

If data is written by AFP from Mac OS X, the system processing speed may slow down. If this happens, try using SMB to write data. If NFS is set to kernel mode, files and folders written using NFS are not copied to the backup TeraStation. The NFS setting can be changed from kernel mode to user mode in the TeraStation's Web Admin interface by navigating to [File Sharing] next to [NFS] - [Edit].
Settings that are not saved to the backup TeraStation: The settings below are not copied from the main TeraStation to the backup TeraStation.

Updating of firmware Notes: To perform any of the above operations, change to maintenance mode temporarily. • To change to maintenance mode, in the main TeraStation's Web Admin interface, navigate to [Backup] next to [Failover] and click [Maintenance mode]. After the operation is completed, click [Cancel maintenance mode]. • If failover is configured, change to maintenance mode before updating the firmware on the TeraStation. • The settings for the backup TeraStation cannot be changed even if it is in maintenance mode.
Ethernet cable connection methods: Use of the configurations below is recommended when making connections with Ethernet cables. Use fixed IP addresses. Because the IP address of the TeraStation designated as the backup cannot be changed, set the IP address before configuring failover.

Connecting to the network at LAN port 1 and setting failover at LAN port 1
Connecting to the network at LAN port 1 and setting failover at LAN port 2
Note: If both LAN ports 1 and 2 are connected as shown in the figure above, then the backup TeraStation will not take over operation from the main TeraStation even if the cable connected to LAN port 1 of the main TeraStation is disconnected.
Using with UPS: Once failover is configured, you will not be able to set up a UPS link for the backup TeraStation. So, 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 are not copied to the backup TeraStation. UPS settings for both TeraStations should be configured before configuring failover. In the Web Admin interface of the backup TeraStation, if [Sync with the UPS connected to another TeraStation on the same network. ] is selected so that operation is linked 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, connect the UPS communication cable from the main TeraStation to the backup TeraStation and reconfigure the UPS link settings.
Use the same model and same capacity TeraStation for the main TeraStation and backup TeraStation. If the capacity of the main TeraStation is larger than that of the backup TeraStation, an error occurs, and files cannot be copied to the backup TeraStation. The message "Replication I33 ReplicateFailure" is displayed on the LCD panel of the main TeraStation. If this happens, disable failover in the Web Admin interface of the main TeraStation.
All data in the TeraStation designated as the backup TeraStation will be erased. Before configuring failover, move any needed data to another hard drive or storage device. Also, during configuration of failover, the backup TeraStation's settings cannot be changed. 101
Failover is intended for TeraStations on the same network. It should not be used for remote backup applications. During failover configuration, the drive capacity of the main TeraStation and backup TeraStation may differ by several megabytes. This is because of a temporary system file. This temporary file is not copied to the backup TeraStation.

Select a TeraStation to be the target backup device.
Notes: • Only one TeraStation can be set as the backup TeraStation. • Check beforehand that no error or information messages appear on the LCD panel of the backup TeraStation.

Enter the administrator password of the target backup device, then click [Start Failover].
10 If the administrator password is correct, the backup TeraStation will beep. 11 To accept the settings from the source TeraStation, hold down the function button on the front of the target TeraStation until it stops beeping. Notes: • To disable failover, in the main TeraStation's Web Admin interface, navigate to [Failover] and click [Dissolve Failover]. Failover can also be disabled by clicking [Dissolve Failover] in the backup TeraStation's Web Admin interface. If failover cannot be disabled, in the main TeraStation's Web Admin interface, navigate to [Backup] next to [Failover] and click [Force Failover to Stop]. After performing a forced disable, restart the main TeraStation and the backup TeraStation. After restarting, check the settings (such as the IP address) and data in the shared folder for both the main TeraStation and the backup TeraStation. After a forced disable, the shared folder of the backup TeraStation is set to read-only. If necessary, configure failover again. • During configuration of failover, if the message "Replication I33 ReplicateFailure" is displayed on the LCD panel, synchronization between the main TeraStation and backup TeraStation has failed. If this occurs, navigate to [Backup] next to [Replication] in the Web Admin interface and choose [Resync]. • If replication is set or was set for multiple folders, initialize the settings before reconfiguring failover. If multiple folders were set before, failover cannot be used even if the settings are changed back to disable replication. This is not a problem, however, if only a single folder was set for replication. • Files are transferred asynchronously. File transfer may take considerable time depending on the network environment or the TeraStation's operating status. • The system processing speed may become slow if the TeraStation is accessed by several users simultaneously. • A large number of files should not be continuously written over a long period of time. • The main TeraStation cannot be used as the backup location for Time Machine supported in Mac OS X. • If the failover operation occurs while email notification is enabled, perform the following operation at the main TeraStation after the failover process is done. Navigate to [Management] next to [Email Notification] [Edit] and click [OK]. This completes the setup.
Maintenance mode: Change to maintenance mode before turning off the TeraStation temporarily or updating the firmware. After changing to maintenance mode, resume failover once the maintenance operation is completed. 103
Procedure for changing to maintenance mode In the main TeraStation's Web Admin interface, navigate to [Backup] mode].
next to [Failover] and click [Maintenance
Procedure for returning from maintenance mode to activated failover status In the main TeraStation's Web Admin interface, navigate to [Backup] nance mode].
next to [Failover] and click [Cancel mainte-
Do not write a large number of files (more than 10,000) to the main TeraStation during maintenance mode. This could cause data synchronization to fail between the main TeraStation and backup TeraStation after resuming failover.
Service IP address setting: The [Service IP Address] in the Web Admin interface is the IP address that overrides the current setting when the backup TeraStation 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. If the same IP address cannot be set, such as due to an IP address conflict, the same IP address may not be inherited. The IP address may also not be inherited in DHCP server environments.
Information shown on LCD panels when operation switches from main TeraStation to backup TeraStation: This message (I49) is displayed on the LCD panel of the backup TeraStation when operation switches from the main TeraStation to the backup TeraStation. FailOver I49 LostMainTarget 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. FailOver E27 LostBackupTarget The above messages may appear when network problems occur even though neither TeraStation has failed. If this happens, log on to the Web Admin interfaces for the main TeraStation and the backup TeraStation to disable failover, then set failover again.

21 Check that Time Machine is on. The seconds displayed in [Next Backup] are counted down and the backup is started when it reaches 0 seconds.
Note: Because the backup operation is performed in the background, Mac OS operations and shutdown can be performed normally. If recovering data or setting items excluded from the backup, refer to the Mac OS Help. This completes the backup procedure using Time Machine.
Backing Up Data from a USB Device Direct Copy can be used to copy the data from a USB device directly to the TeraStation without using a computer by simply connecting the USB device to the USB port of the TeraStation. Note: The devices that can be connected to the USB port of the TeraStation include USB mass storage devices, card readers (except for card readers that can recognize two or more memory cards), digital cameras and other PTP devices, UPS devices that are specifically indicated as compatible, and USB printers. Other USB devices such as USB hubs, mice, and keyboards are not supported.
