• The example above shows access restriction by user. To restrict access by group, click the Local Groups tab and select group permissions.

• If both read-only and read and write permissions are given to a user, the user will have read-only access. The most restrictive access always applies.

• For an access-restricted shared folder, if you change the access restrictions of all users and groups from read and write or read only to access prohibited from the user or group list page in Settings, that shared folder can only be accessed by admin users and groups.

Active Directory

If there is an Active Directory environment, the TeraStation will use account information from the Active Directory domain controller to set access restrictions for TeraStation's shared folders. There is no need to perform individual account management for the TeraStation. If multiple TeraStations are installed on the network, the account information is centrally managed in Active Directory, greatly reducing the operations required for installation and management.

Notes:

• If usernames or group names from Active Directory include multibyte characters, you will not be able to configure access restrictions for them.

• The TeraStation supports a domain environment with a maximum of 10,000 users and groups.

1 In Settings, click Network.

• After building an Active Directory domain, the administrator password for joining the domain must be changed at least once, or joining the Active Directory domain will fail.

• The DNS name and NetBIOS name of Active Directory domains should be identical.

• If both read-only and read and write permissions are given, the user will have read-only access. The most

restrictive access setting will apply.

• To use the TeraStation as a member server in an Active Directory domain, the TeraStation should be logged in to the domain and accessed from a computer that is not a member of the domain with a valid domain account.

• If the TeraStation is a member server of an Active Directory domain, you cannot connect as a guest user via AFP.

Page 41

• If your TeraStation is a member server in an Active Directory domain and you change the authentication method to "Workgroup", the account on the domain controller will not be deleted automatically.

• If FTP is enabled, local and domain group access restrictions from the AD network do not work. Use user access restrictions instead.

• If you allow read and write or read-only access for most users, group access restrictions are recommended.

Configuring Access Restrictions for Subfolders

You may restrict access to subfolders in shared folders by configuring the access restrictions from your computer using Windows Explorer. Note: Depending on the environment, the function may not work properly even if it's enabled. We recommend

verifying the functionality before using.

Note: If "Hide Non-Access Permitted Files and Folders" is enabled, non-access permitted sub-files and folders will not be displayed in shared folders.

7 Click OK.

Enabling subfolders' access restrictions finished. Next, configure access restrictions for each user or group for subfolders from Windows Explorer.

You may configure domain users and groups. You should have the TeraStation join your Active Directory domain before configuring the subfolders' access restrictions.

Notes:

• If enabling subfolders' access restrictions for a USB drive, the drive should be formatted by XFS or ext3.

• The UID and GID of domain accounts should be updated before using the subfolders' access restrictions if the

TeraStation joined the AD network while running firmware version 3.00 or earlier and has since updated to version 3.00. To update the UID and GID, navigate to "File Sharing" - "SMB" - "Edit" from Settings and click Update.

• To back up or replicate files to backup or replication destinations with remaining subfolders' access restriction settings, make sure that the same workgroup name, user IDs, and group IDs are configured between backup or replication sources and destinations.

Page 43

• If you enable access restrictions for subfolders and then clear the "Read & execute" checkbox under "Allow" on Windows Explorer for users or groups access permissions, these users or groups cannot be allowed to read and execute even if subfolders' access restrictions are disabled from Settings. If you deny reading and executing on the same window, this will remain after disabling access restrictions.

• If the TeraStation's settings have been initialized but you configure the same UID and GID for new users and groups, the subfolders' access restrictions may be inherited.

Restoring Owner and Permission Settings

If you changed the owner to an unexpected user or lost permissions to specific folder accidentally, restore them by the procedure below.

1 In Settings, click File Sharing.

2 Click to the right of "Folder Setup".

3 Click Advanced Settings for Subfolders.

Chapter 4 Managing Storage

RAID Modes

TeraStations support many types of RAID. The type of RAID arrays available for use depends on how many drives are installed in your TeraStation.

Notes:

• If you change the RAID mode, all data on the array is deleted. This is true for every procedure in this chapter. Always back up any important data before performing actions that affect your RAID array.

• Drive capacity is shown in Settings in actual gigabytes. The Properties window in Windows may show GiB instead, which will be a smaller number.

• If the TeraStation is restarted or shut down while changing the RAID mode, the message displayed on the LCD panel will change from I46 or I47 to I18.

• RAID 5, 6, and 10 are only available for models with 4 or more drives.

RAID 6

RAID 6 arrays are available for TeraStations with 4 or more drives. RAID 6 combines 4 or more drives into a single array. The usable space is equal to the sum of the capacity of all drives minus the capacity of two drives. For example, if 4 drives are combined into a RAID 6 array, the usable space is the sum of the capacity of 2 drives. If 2 drives in the array are damaged, you can recover data by replacing them. If 3 or more drives are damaged, your data is lost.

RAID 5

RAID 5 arrays are available for TeraStations with 3 or more drives. RAID 5 combines 3 or more drives into a single array. The usable space is equal to the sum of the capacity of the drives minus the capacity of one drive. For example, if 4 drives are combined into a RAID 5 array, the usable space is the sum of 3 drives. If one drive in the array is damaged, you can recover data by replacing the damaged drive. If two or more drives are damaged at the same time, your data is lost.

RAID 10

RAID 10 arrays are available for TeraStations with 4 or more drives. In this mode, mirrored pairs of drives in RAID 1 arrays are combined into a RAID 0 array. The usable space is equal to the capacity of the smallest drive multiplied by the number of drives divided by 2.

RAID 1

Combines 2 or more drives into a mirrored array. The available space in the array is the capacity of a single drive. Identical data is written to each drive. If a drive is damaged, data can be recovered by replacing the damaged drive. As long as one drive in the array remains undamaged, all data in the array can be recovered.

Page 46

RAID 0

Combines 2 or more drives into a single array. The usable drive space is the total space of all drives used. This simple RAID mode offers faster performance than RAID modes that include parity. If a single drive in the array fails, then all data in the array is lost.

JBOD

This mode uses the drives inside the TeraStation as individual drives. The drive space you can use is the total capacity of all drives in the TeraStation. If any drive is damaged, then the data on that drive is lost.

Working with RAID Arrays

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

Using JBOD

With JBOD, each drive in the TeraStation is addressed separately. To put drives from an array into JBOD, follow the procedure below.

Adding an External Drive

Connecting an External Drive

Your TeraStation includes USB ports (the number of ports depends on your model), and you can connect external drives to these ports. Once connected, they appear as shared folders on the TeraStation. Formatted drives are detected automatically. Unformatted drives should be formatted in Settings. After a USB drive is recognized, Windows adds "usbdisk x" in Explorer, where "x" is the USB port where the drive is connected.

Compatibility

The following USB devices are supported by the TeraStation:

• USB storage devices

• Card readers (except for card readers that can recognize two or more memory cards)

Buffalo external USB drives are recommended. Supported file systems for external drives are below:

• FAT32

• EXT3

• XFS

• NTFS

• HFS Plus (read-only)

• exFAT

Connect only one device to each USB port of the TeraStation. Note that only the first partition of a connected USB drive is mounted. Additional partitions are not recognized.

Notes:

• Backup data from macOS may include characters that cannot be written to FAT16 or FAT32 drives such as ".DS_ Store". For best results, reformat the drive before using it as a backup target.

• If your USB 3.0 drive is not reconfigured after rebooting the TeraStation, unplug and reconnect it.

• When copying a file that is over 100 MB to a FAT32-formatted USB drive using File Explorer, an error message may

be displayed. In such a case, use an FTP or SFTP connection to copy the file.

Page 57

Dismounting Drives

If the TeraStation is powered on, dismount drives (internal and external) before unplugging them. You may dismount external drives with the function button, or any drive from Settings. If the TeraStation is off, then all drives are already dismounted and may be unplugged safely. Note: Do not dismount internal drives while a RAID array is rebuilding or RMM is being configured. If you do, data on

the drives may be lost.

Dismounting with the Function Button

Note: If using the TS51210RH series TeraStations, dismount USB drives from Settings. When you press the function button, the TeraStation will beep once. Press and hold the button until the TeraStation beeps again and the button starts blinking blue. It will take about 6 seconds. When the dismount is finished, the function button will stop blinking and return to glowing. You may now unplug any USB drives safely. After 60 seconds, the function button will go out and any drives that have not yet been unplugged will be remounted.

Dismounting from Settings

on the brand of drives in your TeraStation. Critical attributes are displayed in bold.

Checking Drive Condition

For Hard Drives

Attributes with current value or worst value less than or equal to the threshold value may be significant. If an attribute reports a failure, or has had one in the past, it will be displayed in the status column. In such a case, replacing that drive is recommended.

For SSD

Confirm the values of the following attributes.

• Lifetime_Remaining - If the current value is less than the threshold, the drive has reached its guaranteed write capacity (TBW). Replacing the drive is recommended.

• Reallocated_Sector_Ct - If the current value is 99 or less, unrecoverable blocks are detected. If the current value is 10 or less, the drive should be replaced with a new drive immediately.

Formatting Drives

Notes:

• Under some circumstances, data deleted when a drive is formatted can be recovered. To ensure that data is "gone forever", a format might not be sufficient. See the "Erasing Data on the TeraStation Completely" section below.

• After a drive is formatted, the "% Used" and "Amount Used" in Settings will not be 0. This is because some drive space is used for the system area.

Page 62

Encrypting Drives

Internal drives (and arrays) can be encrypted with 256-bit AES during formatting. Encrypted drives and arrays are then readable only from that specific TeraStation. To decrypt a drive or array, clear the "Encryption" checkbox and format it again.

Erasing Data on the TeraStation Completely

Under some circumstances, data from formatted drives can be recovered. The drive erasure process in this section does a much more thorough job of erasing data. This procedure is recommended for removing all data from a drive in a way that makes it nearly impossible to recover with current tools. The TeraStation will then be in the following state:

• All drives in JBOD

• An empty shared folder on each drive

• All settings returned to their default values

• All logs deleted

If you remove a drive and then erase all data on the TeraStation, the LCD panel will show the E22 error message and the number of the removed drive. You can still use the TeraStation. Follow the procedure below to completely and permanently erase all data from your TeraStation.

1 In Settings, click Management.

Using the TeraStation as an iSCSI Device

Introduction

iSCSI is a protocol for carrying SCSI commands over IP networks. Unlike traditional SAN protocols such as Fibre Channel, which requires special-purpose cabling, iSCSI can be run over long distances using existing network infrastructure. Normal Windows formatting such as NTFS is supported.

Differences Between NAS and iSCSI

With iSCSI, the TeraStation is connected to a single computer, such as a server. Other computers on the network access files on the TeraStation through the computer it's connected to. The TeraStation can be used as a local drive from Windows Server. Features of Windows Server such as Active Directory can be used normally. As a NAS, the TeraStation is a server, and computers (including other servers) on the network can access shared folders on it directly. A separate server is not required, and features such as backup are built-in.

Network Configuration

Use gigabit or faster network equipment with iSCSI. For best results, a dedicated network for iSCSI is recommended, separate from the regular network. Use static IP addresses for storage devices such as the TeraStation.

Connection Tool

The Microsoft iSCSI Software Initiator is already installed on your computer. You don't need to download and install it.

Creating an iSCSI Volume

To use the TeraStation as an iSCSI drive, create a volume first. Configure the TeraStation as described below.

Notes:

• If the volume settings are changed, all data on the volume will be erased. Before changing any settings, back up any important data.

• The TeraStation can have up to 255 volumes, but we recommend creating no more than 32. Exceeding this volume amount may cause irreparable damage to the unit.

1 In Settings, click Storage.

Page 69

2 Move the iSCSI switch to the position to enable iSCSI.

3 Click to the right of "iSCSI".

4 Click Create Volume.

5 Enter a volume name, volume description, drive or array where a volume will be created, and volume size. Click

OK when finished.

Page 70

If you enabled LVM for the target drive or array, or selected "File I/O" for the "Backstore" option, the volume size that you specify here can be changed later. To change the volume size, refer to the "Expanding Volume Sizes" section below.

6 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.

7 Click OK, then Close.

Note: If you click Disable Connection for the selected volume in Storage - iSCSI in Settings, the selected iSCSI volume can no longer be accessed. If you click Enable Connection, the volume will become accessible from the iSCSI initiator software.

Connecting or Disconnecting Volumes

Note: By default, the IP address of the TeraStation is automatically assigned from a DHCP server. However, in this case, if you turn off and restart the TeraStation, the IP address may be changed and the volumes on the TeraStation may not be accessible. To avoid changing the IP address unexpectedly, using a static IP address for the TeraStation is recommended.

Connecting Volumes

To connect a volume, follow the procedure below. Note: Do not shut down the TeraStation while connecting to an iSCSI volume. It may cause unexpected data erasure.

Make sure all connections are disconnected before shutdown.

1 In Windows, navigate to Control Panel - Administrative Tools - iSCSI Initiator.

Page 71

2 Enter the IP address of the TeraStation into the "Target" field and click Quick Connect.

3 Confirm if the connection is established and click Done.

Connecting a volume is finished.

Formatting Volumes

If using the connected volume for the first time, the volume should be formatted to be used as a local drive. Follow the procedure below for formatting.

1 In Windows, navigate to Control Panel - Administrative Tools - Computer Management.

2 Click Disk Management.

When the "Initialize Disk" screen is displayed, click OK without changing any settings.

3 Right-click the drive volume that shows the status "Unallocated" and click New Simple Volume from the

displayed menu. Follow the screen to finish formatting.

Formatting a volume is finished. When the formatting process is completed, the drive will be visible as an icon in Computer or My Computer and can be used as a normal drive on the computer.

Disconnecting a Volume

1 In Windows, navigate to Control Panel - Administrative Tools - iSCSI Initiator.

The status of the connecting volume will be displayed as "Connected" under "Discovered targets".

2 Select a volume to disconnect and click Disconnect.

3 Click Yes .

4 When the volume status is displayed as "Inactive", the disconnection was carried out properly.

Page 72

Using with Multiple Computers

If the TeraStation is divided into multiple volumes (or drives), it can be used with multiple computers. However, multiple computers cannot be accessed from one volume (or one drive) at the same time.

Checking Whether iSCSI Volume Is Connected

To check whether an iSCSI volume is connected, navigate to Storage - iSCSI. Current volumes will be listed. If "Connected" is displayed under "Connection", the volume is currently connected to the client.

Configuring Access Restrictions

A CHAP name and secret can be configured for the entire iSCSI volume or each existing volume. Access restrictions can be configured so that entering a target CHAP name and secret is required for each connection. The TeraStation can perform mutual authentication (two-way authentication). Dual passwords ensure that only authorized client computers can access the volume on the TeraStation. Follow the procedure below to enable access restrictions.

The first time the backup job runs like a normal backup. In subsequent backups, files added to the source as well as files deleted from the source are kept in the backup folder.

The first backup job runs like a normal backup. As each additional backup job runs, files are added to and deleted from the backup folder. The backup destination folder is always the same size as the backup source folder.

Each time a backup is executed, management information is stored, and only files that have changed are copied or deleted. Data is retrieved from the previous backup file for files that were not changed. This is useful for making backups with limited space or for referencing status at a particular point in time (for use for data snapshot applications). The destination folder for a management backup should be a local folder on this TeraStation or on a USB drive attached to it. The destination folder will be set to read-only. Do not use folders from drives formatted with FAT. You can specify how many backup versions to keep from 1–400, or select "Unlimited" to keep all backups until the drive is full.

Page 95

7 Select the shared folder that will be the replication source and destination, then click OK.

8 Click OK, then Yes .

Notes:

• During setup, you may choose to encrypt and/or compress replication data. Encrypted data will be transferred securely on the network. Compressed data will ease network loading and is recommended for slow or heavily loaded network connections. Either will increase the CPU load on the source TeraStation. Encrypted and compressed data will be decrypted and decompressed on the destination TeraStation.

• A maximum of 64 shared folders can be configured for replication.

• Replication can also be used to copy all data from a share to a share on an attached external drive. Format

the drive with ext3 or XFS before using it for replication. Drives with FAT32 partitions are not supported with replication.

• You can select the first and second level of shared folders and USB drives connected to the TeraStation as the replication source. Folders whose names contain more than 80 alphanumeric characters or "@" cannot be selected. As the replication destination, you can select the first level of shared folders, USB drives, and on/off-subnet NAS devices' shared folders.

• Don't use the same TeraStation for both failover and replication, or replication and Time Machine.

• Don't configure replication from one source folder to multiple destination folders.

Page 96

• If a network problem causes a replication error, unsynced data may be shown as "0" even though replication is incomplete. Click Resync to recover from the replication error. All files from the source folder will be copied to the destination folder.

• To inherit the subfolders' access restriction settings to the replication destination, the replication destination should also support the subfolders' access restrictions. Verify it before creating a replication task.

Synchronizing Between Source and Destination TeraStations Periodically

To copy files that are saved via other file sharing protocols such as AFP or FTP to the replication destination regularly, configure "Periodic Sync" from Settings. Follow the procedure below.

1 In Settings, click Backup.

2 Click to the right of "Replication".

3 Click Periodic Sync.

Page 97

4 Select "Daily" or "Weekly" from the "Schedule" drop-down list. If "Daily" is selected, configure the sync period. If

"Weekly" is selected, specify the week days and the sync period.

5 When the configuration is finished, click OK.

Failover

With failover, two TeraStations are connected to the network for redundancy. If an issue renders the main TeraStation inaccessible, operation automatically switches to the backup TeraStation.

Data on both TeraStations stays up-to-date.

BackupMain

Switches automatically if failure occurs.

Failover will activate during any of the following situations:

• The backup TeraStation cannot detect the main TeraStation within a specified time

If the backup TeraStation has not received a packet from the main TeraStation within a specified time, the backup TeraStation considers the main TeraStation to have failed. By default, it will try 5 times and wait 60 seconds. If this is triggered by accident, reconfigure failover from the main TeraStation.

• Errors

Failover will occur if any of the following errors occur: E12 (cooling failure), E14 (cannot mount RAID array), E16* (drive not found), E22* (cannot mount drive), E30* (drive failure) * When the drive is configured in JBOD.

Notes:

• Only use identical model and capacity TeraStations for failover. If the capacity of the main TeraStation is larger than that of the backup TeraStation, an I33 replication error will occur.

• All drive bays of a TeraStation should be occupied if it will be used for failover. Failover will not work if a drive is missing from any bay.

Before Configuring Failover

Use the same LAN ports for transferring data and configure both TeraStations with static IP addresses for the purposes of failover. It is recommended to use a 10GbE port for failover. This section explains using an example with LAN ports 1 and 3.

Using the Same LAN Port for Both Failover and Connecting to the Network

Using this setup, if the main TeraStation fails, the backup TeraStation will replace it completely. The backup TeraStation will be updated over normal network traffic.

Using Different LAN Ports for Connecting to the Network and Failover

With this setup, the backup TeraStation and main TeraStation are connected by a second Ethernet cable connecting their LAN 3 ports. Updating is done over this dedicated network path, so updates are quicker and don't interfere with normal network traffic.

Usage Restrictions

Functional Restrictions

Failover is not available when any of the following functions are enabled: Replication, sleep mode, encrypted drive volume, LVM volume, iSCSI volume, port trunking, cloud storage*, Dropbox Sync, hot spare, access restrictions by Active Directory domain * Even if the function is disabled, the settings may remain if the settings were configured beforehand. Initialize all settings before configuring failover.

Setting Restrictions

The following functions will not be available while failover is enabled: Initializing settings, changing the RAID settings, formatting drives, iSCSI volume, changing the backup TeraStation's settings, turning the TeraStation on and off, updating the firmware

While failover is enabled, shutdown, power-on, and firmware update operations can be made available by temporarily changing the TeraStation to maintenance mode. Maintenance mode can be enabled or disabled at

Backup - Failover in the main TeraStation's Settings. Click Maintenance mode to enable maintenance mode, or click Cancel maintenance mode to disable maintenance mode.

To update the firmware while in maintenance mode, the main TeraStation can be updated from Settings, but the backup TeraStation cannot. Download the firmware updater from the Buffalo website for the backup TeraStation and try updating the firmware through it.

Non-Transferable Settings

The settings below are not copied from the main TeraStation to the backup TeraStation. Make a note of the original settings so that they can be configured manually if failover errors. WebAccess*, UPS synchronization, antivirus**, the backup job settings either if specifying shared folders on the backup TeraStation or USB drives as the backup destination, and USB drives' shared folder settings * If the backup TeraStation took over the main TeraStation's IP address after failover, the WebAccess settings will not be copied. Re-register your BuffaloNAS.com account for WebAccess. If the backup TeraStation kept its IP address, the settings will be copied from the main TeraStation. ** The settings configured on the Trend Micro NAS Security settings page will not be copied to the backup TeraStation. The settings configured on the main TeraStation's Settings page will be copied. Only if the antivirus is activated on the TeraStation.

Using with UPS

Once failover is configured, you cannot set up a UPS for the backup TeraStation. Configure your UPS before configuring failover. UPS recovery can be configured for both the main and backup TeraStations.

Configuring Failover

1 In Settings for the main TeraStation, click Backup.
