Configuring Access Restrictions for Shared Folders

You may restrict access for specific shared folders, including external USB drives.

Notes:

· Configure access restrictions only through Settings. Configuring access restrictions through Windows is not supported and may cause unexpected behavior.

· Shared folders with limited access can still be used as backup destinations.

· If you grant both read-only and read and write access to the users or groups, the attributes will become as below:

Group with read and write access

Group with read-only access

Group with no access

User with read and write access

R/W

User with read-only access

User with no access

R/W

R/W: Read and write, R: Read-only, -: No access
· If you change access restrictions for a user or group while they are accessing files, unexpected behavior may occur.

Chapter 3 File Sharing Notes: · The example above shows access restrictions by users. To restrict access by group, click the Local Groups tab and
select group permissions. · 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 From Settings, click Network.
2 Click the settings icon ( ) to the right of "Workgroup/Domain".
3 Click Edit. 4 Select "Active Directory", then click Next.

: No access

13 Click OK.

Notes:
· To have the TeraStation join an Active Directory domain, configure it to use a DNS server that can resolve names for the Active Directory domain.
· After building an Active Directory domain, the administrator password for joining the domain must be changed at least once, or joining the Active Directory domain will fail.
· The DNS name and NetBIOS name of Active Directory domains should be identical.
· If the TeraStation is a member server of an Active Directory domain, you cannot connect as a guest user via AFP.
· If your TeraStation is a member server in an Active Directory domain and you change the authentication method to "Workgroup", the account on the domain controller will not be deleted automatically.
· If FTP is enabled, local and domain group access restrictions from the AD network do not work. Use user access restrictions instead.
· For an access-restricted shared folder, if you change the access restrictions of all users and groups from read and write or read-only to access prohibited from the user or group list page in Settings, that shared folder can only be accessed by admin users and groups.
· If you allow read and write or read-only access for most users, group access restrictions are recommended. 44

Chapter 3 File Sharing · Depending on the domain controller's policy settings, the domain controller may force the TeraStation to leave
the Active Directory domain. If this occurs, the TeraStation will lose the domain users and groups so if you have configured access restrictions using domain accounts, these users will no longer be able to access shared folders. In such a case, change the policy settings on the domain controller or let the TeraStation join the Active Directory domain again.
Configuring Access Restrictions for Subfolders
You may restrict access to subfolders in shared folders by configuring access permissions from your computer using Windows File Explorer. Notes: · Depending on the environment, the function may not work properly when enabled. We recommend verifying
the functionality before using. · Access permissions configuring from File Explorer is available for up to 18 files and 24 folders. This number of
available access permissions may vary if access permissions are inherited from the parent object. The number of available access permissions are not many so using group access permissions is recommended if the permission level is the same to the multiple users; it will save spending the number of available access permissions.
Enabling Subfolders' Access Restrictions
1 From Settings, click File Sharing.
2 Click the settings icon ( ) to the right of "Folder Setup".
45

Chapter 3 File Sharing
3 Click the shared folder that you want to set access restrictions for.
4 Clear all checkboxes for "LAN Protocol Support" other than "SMB (Windows/Mac)", "Backup", and "NFS". 5 Click the Option 2 tab. 6 Enable "Access Restrictions for Subfolders".
Note: If "Hide Non-Access Permitted Files and Folders" is enabled, non-access permitted sub-files and folders will not be displayed in shared folders.
7 Click OK.
Enabling subfolders' access restrictions finished. Next, configure access permissions for each user or group to files and folders in subfolders from File Explorer.
46

Chapter 3 File Sharing
You may also configure access permissions for domain users and groups. You should have the TeraStation join your Active Directory domain before configuring access permissions from File Explorer. Notes: · If enabling subfolders' access restrictions for a USB drive, the drive should be formatted using XFS or ext3. · The UID and GID of domain accounts should be updated before using the subfolders' access restrictions if the
TeraStation had joined the AD network while running a firmware version earlier than 3.00 (and has since updated to version 3.00 or later). To update the UID and GID, navigate to File Sharing > SMB > Edit in Settings and click Update. · To back up or replicate files to backup or replication destinations with access permission settings of files and folders in subfolders unchanged, make sure that the same workgroup name, user IDs, and group IDs are configured between backup or replication sources and destinations. · If you clear the "Read & execute" checkbox under "Allow" (as shown on the image above) and disable the subfolders' access restrictions, the listed users and groups will have read and write permission. · If the TeraStation's settings have been initialized but you configure the same UID and GID for new users and groups, access permissions to files and folders in subfolders may be inherited.
Restoring Owner and Permission Settings
If you changed the owner to an unexpected user or accidentally lost permissions to a specific folder, restore them by following the procedure below.
1 From Settings, click File Sharing.

RAID Modes
The TeraStation supports many types of RAID. The type of RAID arrays available for use depends on how many drives are installed on 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. · Some RAID arrays allow you to change the RAID mode without losing data by adding drives. To change a RAID
mode by adding drives to the existing array, refer to the "Expanding RAID Capacity Without Deleting Data" section below. · Drive capacity is displayed 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 that appears on the LCD panel will change from I46 or I47 to I18. · RAID 5, 6, and 10 are only available for TeraStation models that allow three or more drives to be inserted. Please check Settings on your model before changing the RAID mode.
RAID 6
RAID 6 arrays are available for TeraStations with four or more drives. RAID 6 combines four 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 four drives are combined into a RAID 6 array, the usable space is the sum of the capacity of two drives. If two drives in the array become damaged, you can recover data by replacing them. If three or more drives become damaged, then all data in the array will be lost.
RAID 5
RAID 5 arrays are available for TeraStations with three or more drives. RAID 5 combines three 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 four drives are combined into a RAID 5 array, the usable space is the sum of three drives. If one drive in the array becomes damaged, you can recover data by replacing the damaged drive. If two or more drives become damaged at the same time, then all data in the array will be lost.
RAID 10
RAID 10 arrays are available for TeraStations with four 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 two.
RAID 1
Combines two or more drives into a mirrored array. The usable space is equal to the capacity of a single drive. Identical data is written to each drive. If a drive becomes 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.
51

Chapter 4 Storage Management
RAID 0
Combines two or more drives into a single array. The usable space is equal to the total capacity of all drives in the array. This simple RAID mode offers faster performance than RAID modes that include parity. If a single drive in the array becomes damaged, then all data in the array will be lost.
JBOD
This mode uses the drives inside the TeraStation as individual drives. The usable space is equal to the total capacity of all drives on the TeraStation. If any of the drives become damaged, then all data on that drive will be lost.
Working with RAID Arrays

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. 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.
Connection Tool
The Microsoft iSCSI Software Initiator is already installed on your computer. You don't need to download and install it.
Creating an iSCSI Volume
To use the TeraStation as an iSCSI drive, create a volume first. Configure the TeraStation as described below. Notes: · If the volume settings are changed, all data on the volume will be erased. Before changing any settings, back up
any important data. · The TeraStation can have up to 255 volumes, but we recommend creating no more than 32. Exceeding this
volume amount may cause irreparable damage to the unit. · Do not use any of the following words for the name of a volume as these words are reserved for internal use by
the TeraStation: array x, authtest, disk x, global, homes, info, lost+found, lp, mediacartridge x, msdfs_root, mtdaapd, printers, ram, spool, usbdisk x. Any instances of "x" denote a number (for example: array1 or disk3)

Using with Multiple Computers
If the TeraStation is divided into multiple volumes (or drives), it can be used with multiple computers. However, it is not recommended to access a single volume or drive from multiple computers at the same time for security reasons. When using the TeraStation as an iSCSI device, it should only connect to a single initiator unless the computer running the initiator also has clustering enabled and configured on its operating system. To avoid using multiple initiators for access, enable mutual authentication. 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 "Status", 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.

Backup Modes
The following types of backup are available from this TeraStation. To restore data from backup, refer to the "Restoring Backup Data" section below.

Full Backup
All files in the source will be backed up to the destination. You can specify how many backup versions to keep from 1400, or select "Unlimited" to keep all backups until the drive is full. If you specify a number of backup versions, the backup destination folder should be on the same TeraStation or on an external USB drive attached to that TeraStation. The backup data will be stored in the folder whose name will be the backup date and time. · Folders available as backup sources:
Shared folder on the backup source TeraStation (excluding the "info" folder)*1 USB drive connected to the backup source TeraStation Shared folder on another Buffalo NAS device*2 Shared folder on another rsync-compatible device · Folders available as backup destinations: Shared folder on the backup source TeraStation (excluding the "info" folder)*2 USB drive connected to the backup source TeraStation*2, 3 Shared folder on another Buffalo NAS device*2, 3, 4 Shared folder on another rsync-compatible device
*1 You can select up to the second level of folders. However, if the folder name of a second level folder contains "@", that folder may not appear as the target folder. *2 The folder should have the "Backup" checkbox selected under "LAN Protocol Support" on the shared folder settings.
91

Chapter 5 Backup
*3 If the "Inherit subfolders' access restrictions" option is selected when creating a backup job, use XFS or ext3 file systems. *4 If the "Inherit subfolders' access restrictions" option is selected when creating a backup job, the device should be a Buffalo NAS device whose subfolders' access restrictions is available.
Overwrite (Incremental)
The first backup job runs like a full backup. As each subsequent backup job runs, only files that have been changed since the last full backup will be backed up, but any files deleted from the backup source folder will also remain in the backup destination folder. The folder structure in the backup destination folder will be the same as the backup source folder. · Folders available as backup sources:
Shared folder on the backup source TeraStation (excluding the "info" folder)*1 USB drive connected to the backup source TeraStation Shared folder on another Buffalo NAS device*2 Shared folder on another rsync-compatible device · Folders available as backup destinations: Shared folder on the backup source TeraStation (excluding the "info" folder)*2 USB drive connected to the backup source TeraStation*2, 3 Shared folder on another Buffalo NAS device*2, 3, 4 Shared folder on another rsync-compatible device
*1 You can select up to the second level of folders. However, if the folder name of a second level folder contains "@", that folder may not appear as the target folder. *2 The folder should have the "Backup" checkbox selected under "LAN Protocol Support" on the shared folder settings. *3 If the "Inherit subfolders' access restrictions" option is selected when creating a backup job, use XFS or ext3 file systems. *4 If the "Inherit subfolders' access restrictions" option is selected when creating a backup job, the device should be a Buffalo NAS device whose subfolders' access restrictions is available.
Overwrite (Differential)
The first backup job runs like a full backup. As each subsequent backup job runs, only files that have been changed since the last full backup will be backed up, and any files deleted from the backup source folder will also be deleted from the backup destination folder. The backup destination folder will always remain the same size as the backup source folder, and the folder structure in the backup destination folder will be the same as the backup source folder. · Folders available as backup sources:
Shared folder on the backup source TeraStation (excluding the "info" folder)*1 USB drive connected to the backup source TeraStation Shared folder on another Buffalo NAS device*2 Shared folder on another rsync-compatible device · Folders available as backup destinations: Shared folder on the backup source TeraStation (excluding the "info" folder)*2 USB drive connected to the backup source TeraStation*2, 3 Shared folder on another Buffalo NAS device*2, 3, 4 Shared folder on another rsync-compatible device
*1 You can select up to the second level of folders. However, if the folder name of a second level folder contains "@", that folder may not appear as the target folder. *2 The folder should have the "Backup" checkbox selected under "LAN Protocol Support" on the shared folder settings. *3 If the "Inherit subfolders' access restrictions" option is selected when creating a backup job, use XFS or ext3 file systems.
92

Chapter 5 Backup
*4 If the "Inherit subfolders' access restrictions" option is selected when creating a backup job, the device should be a Buffalo NAS device whose subfolders' access restrictions is available.
Management Backup
Each time a backup is executed, management information is stored, and only files that have changed are backed up. Data is retrieved from the previous backup file for files that were not changed, which can help reduce the space used for backup and also for referencing status at a particular point in time (for data snapshot applications). You can specify how many backup versions to keep from 1400, or select "Unlimited" to keep all backups until the drive is full. If using an external USB drive as the backup destination, do not use folders from drives formatted with FAT. The backup data will be stored in the folder whose name will be the backup date and time, and the destination folder will be set to read-only. · Folders available as backup sources:
Shared folder on the backup source TeraStation (excluding the "info" folder)* USB drive connected to the backup source TeraStation Shared folder on another Buffalo NAS device** Shared folder on another rsync-compatible device · Folders available as backup destinations: Shared folder on the backup source TeraStation (excluding the "info" folder) USB drive connected to the backup source TeraStation
*You can select up to the second level of folders. However, if the folder name of a second level folder contains "@", that folder may not appear as the target folder. **The folder should have the "Backup" checkbox selected under "LAN Protocol Support" on the shared folder settings. Note: For the destination folder, do not use a folder that has already been used as a target folder for another backup job. If you wish to use a folder that currently contains backup data as the destination folder for another backup job, format the folder first, or delete all data in the destination folder and change the folder attribute to read and write before configuring the folder as the destination folder.
Preparing a Backup Destination
Configure a shared folder on a Buffalo NAS device or connected USB drive as a backup destination. The following procedure explains using another shared folder on the TeraStation as a backup destination. The procedure may vary depending on which Buffalo NAS device is selected as a destination. If using a USB drive as a backup destination, make sure its attribute is set to read and write. To change a read-only USB drive's attribute to read and write, refer to the "Read-Only Shares" section in chapter 3. If you would like to back up data from multiple backup sources, we recommend not using the same backup destination, as data in the backup destination may be overwritten by subsequent backup jobs. If you must back up data from multiple backup sources to the same backup destination, using management backup is recommended for precise version control. Note: If you want to set this TeraStation as the backup destination for an rsync-compatible device, refer to the "If Backing Up from rsync-Compatible Devices to the TeraStation" section instead of following the procedure below.
1 From Settings, click File Sharing.
2 Click the settings icon ( ) to the right of "Folder Setup".
3 Choose the folder to be set as a backup destination.

Notes: · Up to eight backup jobs can be configured at a time, and twenty-five backup source and destination folder pairs
can be used in one backup job. · To inherit the subfolders' access restriction settings to the backup destination, the backup destination should also
support the subfolders' access restrictions. Check it before creating a backup job. · To back up data between Buffalo NAS devices on a network using jumbo frames, make sure that both devices are
configured to use identical (or similar) MTU sizes. If MTU sizes are significantly different, the backup job may not be properly performed. In such a case, select the default MTU size (1,500 bytes) for both devices. · You can also specify a hostname by a fully qualified domain name (FQDN). · Windows-based TeraStations with multibyte characters in the hostname may not be detected as a backup destination, and folders in these devices cannot be used as backup destination folders. · Backup data, such as ".DS_Store" files, from macOS may include characters that cannot be read on FAT32formatted drives in its filename. For best results, reformat the drive before using it as a backup destination.
If Backing Up from rsync-Compatible Devices to the TeraStation
If you want to set an rsync-compatible device as the backup source and back up data on the rsync-compatible device to the TeraStation, you will need to enable rsync access on the TeraStation.

position to enable rsync.

Restoring Backup Data
The procedure for restoring backup data varies depending on the backup mode. Refer to the following subsection corresponding to the backup mode you have used for backup. When restoring backup data, make sure you have enough available space on the TeraStation to accommodate the backup data, otherwise the restore process will fail.
Full and Management Backups
Copy and paste the backed up files from the backup destination folder to a folder which you want to restore.
Overwrite Backups (Incremental and Differential)
Files and folders have already been stored on the desired destination. You can access them by switching the operation to the backup destination TeraStation. Alternatively, you can restore any files or folders by creating a backup job and configuring the backup destination as a backup source and selecting the same backup mode for the "Operation Mode" drop-down list. Please do not use the same folder as the backup destination to restore backup data from multiple backup sources, as this may cause the restored data to get overwritten.

Failover

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

Main

Data on both TeraStations stays up-to-date.

Backup

Switches automatically if failure occurs.

Failover will activate if any of the following occurs: · 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 five 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) *This triggers 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.
Using the Same LAN Port for Both File Sharing and Failover
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.

13 Choose the folder to restrict access to, and enter the clients that will have restricted access into the "Hosts"
field. Clients may be entered by hostname, IP address, or IP address range. Wildcards are supported. Separate multiple entries with commas. You may assign read-only or read and write access to the listed clients. Rules override any settings made from the Services tab.
14 Click OK.
187

Chapter 7 Advanced Features
Notes: · To restrict NFS access to a specific network or client, navigate to File Sharing > NFS > Services and click Edit. Enter
the address of the network. For example, if your local network subnet has a router at 192.168.1.1 and clients with IP addresses in the range from 192.168.1.2 through 192.168.1.48 with subnet mask 255.255.255.0, then the "Public Network Address" would be 192.168.1.0 and the "Public Subnet Mask" would be 255.255.255.0. This would mean that only clients on this local network would be able to access the NFS share. If the default settings are used (0.0.0.0 for both the public network address and the public subnet mask), then access to the NFS share will not be restricted. · If you configure "Guest Permission" to "Forced" on the screen after navigating to NFS Rules > Add, the user ID and group ID should be 65534 when the data is written from NFS clients; this is recommended for SMB or other protocols as well. If the TeraStation only enables the NFS connection, use "Ignored" instead. · Be aware that some NFS clients may be able to access via NFS although the clients do not exist in the allowed NFS client list.
NFS Mount Commands
Enter the mount command to access the shared folder from the NFS client. The mount command depends on your operating system. The examples below assume that IP address of your TeraStation is 192.168.11.10, "/mnt/array1/ share" is the desired NFS path, and "/mnt/nas" or drive letter "z" is the mount point. For Linux: mount -t nfs 192.168.11.10:/mnt/array1/share /mnt/nas For Windows Service for Unix 3.5: mount 192.168.11.10:/mnt/array1/share z: Note: A shared folder whose folder name contains multibyte characters cannot be accessed. For Solaris 10: mount -F nfs 192.168.11.10:/mnt/array1/share /mnt/nas For macOS: mount -t nfs -o resvport 192.168.11.10:/mnt/array1/share /mnt/nas
Encrypting Data Transmission
Encrypting Settings Data
All communication with Settings can use SSL encryption if you access the Settings page by changing "http://" to "https://" in the browser address bar or click Secure Connection from the login window. Once you are logged in using the HTTPS connection and wish to disable SSL encryption, click Normal Connection from the login window.
Encrypting FTP Transfer Data
You can encrypt passwords using SSH for secure FTP communication. First, open a shared folder's settings; under "LAN Protocol Support", select the "SFTP" checkbox on the Basic tab and click OK. Also, you have to enable the SFTP service by moving the SFTP switch to the on position on "File Sharing".
SSL
SSL (Secure Socket Layer) is a protocol that uses a public key encryption system to establish secure communication channels between networked devices, allowing for encrypted Internet traffic and server identity verification. The SSL protocol uses a pair of keys one private, one public to authenticate and manage secure connections. SSL keys are used during setup screen operations and FTP communication.
SSL Key Formats/Extensions
The SSL keys may include the following encoding formats and extensions:
188

Chapter 7 Advanced Features
SSL Certificate (server.crt) The server.crt is the server public key, and is generated by the TeraStation. A computer that receives the server.crt uses it to encrypt data, and the TeraStation then uses the server.key file to decrypt the data. In SSL, this key contains the server certificate, and depending on your computer environment, a check may be performed to determine the trustworthiness of the certificate. The server certificate included in the TeraStation's default settings was created by Buffalo, and in some cases, the security certificate warning message may appear in your browser or another security software. If this occurs, disregard the message and continue.
SSL Private Key (server.key) This file is the server private key, and it is usually not revealed. The server.key file is paired with the server.crt file to decrypt data encrypted by the SSL certificate. Note: The passphrase for the private key must be removed before importing to the TeraStation.
Updating SSL Key Files
To update a server certificate and a private key for SSL, follow this procedure.
1 From Settings, click Management. 2 Click SSL. 3 Register "server.key" for "Secret Key" and "server.crt" for "Server Certificate (.crt)", then click Import.
Notes: · Place the SSL key files (server.key, server.crt) directly below the C root drive. The SSL key files may be unable to be
updated if they are placed in folders or paths that contain multibyte characters. · If Settings cannot be displayed after updating, initialize the TeraStation settings. · Updating the firmware initializes an SSL key.

Even though the data is deleted, the RAID array will be kept as is. · Assigning the TeraStation a static IP address is recommended for boot authentication. · When boot authentication settings finish, export the configuration file for backup. Refer to the "Exporting Managed TeraStations to a File" section in the Boot Authentication Tool help for the procedure. · Boot authentication cannot be enabled if any of the following functions are enabled: drive encryption, LVM, iSCSI, and failover. Conversely, these functions cannot be enabled while boot authentication is enabled.
Important Notice
This feature was developed with the intention of preventing critical data leakage by rendering the TeraStation unusable in cases of misoperation or missing important setting files. Before configuring boot authentication, back up the data on the TeraStation by referring to the "Backing Up Data on the TeraStation" section in chapter 5, and then create a USB initialization drive by referring to the "Creating a USB Initialization Drive" subsection above. With these preparations, a TeraStation that is unusable may be initialized and reverted to a usable state. If any of the situations below occur, the TeraStation will stop booting and become inaccessible. · The TeraStation is unable to communicate with the authentication server due to the server crashing or it being
on another network. · The TeraStation unit has been deleted from Boot Authentication Tool or the Boot Authentication Tool database
has been erased. · Security level is configured to "High" and the incorrect passcode is entered three times.
