• File and folder names may contain up to 255 single-byte characters.
• Folder and workgroup names whose names contain non-Roman characters may not be displayed correctly.
• If shared folders are accessed from a Mac, information files for the Mac may be generated automatically. Do not
delete these files. If they are deleted from a Windows device, this may prevent further access from a Mac.
• The LinkStation belongs to the default zone in AppleShare; the zone cannot be specified.
• When files are copied to the LinkStation or to a USB drive connected to the LinkStation, file information such as
date created, date modified, and other date information may be updated or changed.
• During a file transfer, if settings are changed, the file transfer operation may be aborted.
• File copying to the LinkStation is protected by a journaling file system. If the Ethernet cable is disconnected or a
power outage occurs while copying data, the following may occur:
◦Preset data such as the LinkStation name, users, and groups may be erased.
◦An incomplete file may be copied and the file can no longer be deleted. If this occurs, restart the LinkStation,
delete the file, and perform the copy operation again.
Recycle Bin
To protect your data from accidental deletion, you may configure your LinkStation to use a recycle bin instead of
deleting files immediately. The recycle bin will only work with SMB connections.
Read-Only Shares
By default, new shares are set with read and write access, but you may change the folder attribute to read-only.
Follow the procedure below to change the shared folder attribute to read-only.
1 From Advanced Settings, navigate to [File Sharing] > [Folder Setup] and choose a shared folder.
2 Click [Edit] and change the “Attribute” option to “Read Only”, then click [OK].
Read-only shares and HFS Plus-formatted USB drives will have “(Read Only)” added to comments in File Explorer.
Note: Configure the share attribute only through Settings. Configuring folder attributes through Windows is not
supported and may cause unexpected behavior.
Hidden Shares
If a shared folder becomes hidden, it will not be displayed under Network, and only certain users will be allowed to
access it. To hide a shared SMB folder, follow the procedure below.
1 From Advanced Settings, navigate to [File Sharing] > [Folder Setup] and choose a shared folder to make
hidden. A USB drive is not available as a hidden share.
2 Select the “Hidden Share (SMB Only)” checkbox and click [OK].
24
Chapter 3 File Sharing
Notes:
• If protocols other than “SMB (Win/Mac)” or “Backup” under “LAN Protocol Support” are enabled, the hidden shares
option will be grayed out and cannot be selected.
• Configure hidden share attributes only through Settings. Configuring them through Windows is not supported
and may cause unexpected behavior.
To access a hidden folder, open File Explorer in your computer and enter “\\LinkStation name\shared folder name$\”
into the address bar. For example, if the LinkStation name is “LSXXX001” and the shared folder name is “share”, enter
“\\LSXXX001\share$\” to open it.
Configuring Users
Adding a User
Follow the procedure below to create a user. To create a user from a mobile device, refer to the “Adding a User”
section in chapter 9.
Note: The LinkStation can register a maximum 300 of users, which includes the default users “admin” and “guest”.
1 From Advanced Settings, click [File Sharing].
2 Click to the right of “Users”.
25
Chapter 3 File Sharing
3 Click [Create User].
26
Chapter 3 File Sharing
4 Enter the desired settings, then click [OK].
Notes:
• Usernames may contain up to 128 alphanumeric characters, hyphens (-), underscores (_), periods (.), and the
symbols ! # & @ $ * ^ %. The first character should not be a symbol.
• The user ID should be a number from 1000 to 1999. Each user ID should be unique. If this field is left blank, a user
ID is assigned automatically.
• Do not duplicate user IDs, group IDs, usernames, or group names. Each should be distinct and unique.
• User descriptions may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces.
Multibyte characters are supported. The first character should not be a symbol or space.
• Passwords may contain up to 20 alphanumeric characters, hyphens (-), underscores (_), commas (,), periods (.),
semicolons (;), tildes (~), and the symbols @ ! # $ % & ' ) ( * + / > < = ? " ] [ ^ } { |. The first character should not be a
symbol unless it is an underscore.
• Use the same username and password for both Windows and the LinkStation or you may be unable to access
shared folders.
• If a user belongs to multiple groups, the most strict access restrictions will apply. For example, if a user is added to
a group with read and write access, and also to a read-only group, the user will effectively have read-only access.
• Do not use any of the following words as a username as these words are reserved for internal use by the
LinkStation: adm, admin, administrator, all, apache, bin, daemon, disk, ftp, ftpuser, guest, halt, hdusers, kmem,
lp, mail, man, mysql, news, nobody, nogroup, none, operator, root, shadow, shutdown, sshd, sync, sys, tty, users,

Chapter 3 File Sharing
Converting Local Users into External Users
If using an external SMB server for authentication, you may convert any local users into external users. This way, the
LinkStation will have a user list that matches the users in the external SMB server, and access restrictions for this
LinkStation’s shared folders may be assigned to the converted “external” users.
Follow the procedure below to convert a local user into an external user. If a local user is converted, their user
information (including passwords) will be removed from the LinkStation. External users cannot be reverted to local
users.
Note: External authentication should be enabled before local users can be converted. For more information on
external authentication, refer to the “User Authentication with an External SMB Server” section.
1 From Advanced Settings, click [File Sharing].
2 Click to the right of “Users”.
3 From the user list screen, select the checkboxes of any users to be converted to an external user, then click
[Convert to External User].
4 Click [OK].
5 The “Confirm Operation” screen will open. Enter the confirmation number, then click [OK].
Converted users are displayed under the “External Users” tab. You can then configure access restrictions for external
users.

29
Chapter 3 File Sharing
4 Enter the desired settings, then click [OK].
Notes:
• Group names may contain up to 20 alphanumeric characters, hyphens (-), underscores (_), and periods (.). The
first character should not be a symbol unless it is an underscore.
• Group descriptions may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces.
Multibyte characters are supported. The first character should not be a symbol or space.
• If the group ID field is left blank, a group ID is automatically assigned. Use numbers between 1000 and 1999 to set
a group ID manually. Don’t use duplicate group IDs.
• You may register up to 300 groups with the LinkStation.
• If you are logged in as an administrator, you can change any setting, including other users’ passwords. If you are
logged in as a member of the power users group, you can create and edit shared folders, users, and groups. If you
are logged in as a member of the general users group, you can change only your own password.
• Do not use any of the following words as a group name as these words are reserved for internal use by the
LinkStation: adm, admin, administrator, all, apache, bin, daemon, disk, ftp, ftpuser, guest, halt, hdusers, kmem,
lp, mail, man, mysql, news, nobody, nogroup, none, operator, root, shadow, shutdown, sshd, sync, sys, tty, users,

Configuring Access Restrictions
You may restrict access for specific shared folders, including external USB drives.
Follow the procedure below to configure access restrictions. To configure access restrictions from a mobile device,
refer to the “Configuring Access Restrictions” section in chapter 9.
30
Chapter 3 File Sharing
Notes:
• Access restrictions can be set separately for each shared folder, but not for subfolders within the shared folders.
• Configure access restrictions only through Settings. Configuring access restrictions through Windows is not
supported and may cause unexpected behavior.
Local Users and Groups
1 From Advanced Settings, click [File Sharing].
2 Click to the right of “Folder Setup”.
3 Click the shared folder that you want to set access restrictions for.
4 Click [Edit].
5 Enable “Access Restrictions”.
6 Select the level of access for the user or group.
31
Chapter 3 File Sharing
: Read and write : Read-only : No access
7 Click [OK].
Notes:
• The example above shows access restrictions by users. To restrict access by group, click the [Local Groups] tab and
select group permissions.
• The most restrictive access settings will always apply. For example, if both read-only and read and write
permissions are given to a user, the user will have read-only access.
Active Directory
If there is an Active Directory environment, the LinkStation will use account information from the Active Directory
domain controller to set access restrictions for LinkStation’s shared folders. There is no need to perform individual
account management for the LinkStation. If multiple LinkStations are installed on the network, the account
information is centrally managed in Active Directory, greatly reducing the operations required for installation and
management.
Note: The LinkStation supports a domain environment with a maximum of 1000 users and groups.
1 From Advanced Settings, click [Network].
2 Click to the right of “Workgroup/Domain”.
3 Click [Edit].
32

33
Chapter 3 File Sharing
8 Click the shared folder that you want to set access restrictions for.
9 Click [Edit].
10 Enable “Access Restrictions”.
11 Select the level of access for the user or group.
: Read and write : Read-only : No access
12 Click [OK].
Notes:
• If you change the LinkStation’s name, you will no longer be able to use domain users and groups or access
restrictions. To repair this, rejoin the domain.
• To have the LinkStation 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.
• The most restrictive access settings will always apply. For example, if both read-only and read and write
permissions are given to a user, the user will have read-only access.
• If there is a difference of more than five minutes between the LinkStation’s clock and the domain controller’s
clock, joining the domain or authenticating domain users and groups may fail. For best results, use an NTP server
to set the time for all network devices.
• To use the LinkStation as a member server in an Active Directory domain, the LinkStation 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 LinkStation is a member server of an Active Directory domain, you cannot connect as a guest user via AFP.
• If your LinkStation 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.
34
Chapter 3 File Sharing
• When the LinkStation joins an Active Directory domain, FTP is disabled. Before using FTP, move the FTP switch
back to the on position.
• Don’t disable the SMB protocol while Active Directory is used for access restrictions. If you do, you will need to
enable SMB again and reconfigure AD from scratch.
NT Domain
If there is an NT domain environment, the LinkStation will use account information from the NT domain server to set
access restrictions for LinkStation’s shared folders. There is no need to perform individual account management for
the LinkStation. If multiple LinkStations are installed on the network, the account information is centrally managed
in the NT domain, greatly reducing the operations required for installation and management.
Note: The LinkStation supports an NT domain environment with a maximum of 1000 users and groups.
1 From Advanced Settings, click [Network].
2 Click to the right of “Workgroup/Domain”.
3 Click [Edit].

Chapter 3 File Sharing
12 Click [OK].
Notes:
• If you change the LinkStation’s name, you will no longer be able to use domain users and groups or access
restrictions. To repair this, rejoin the domain.
• The most restrictive access settings will always apply. For example, if both read-only and read and write
permissions are given to a user, the user will have read-only access.
• If a domain username is more than 20 bytes long, the LinkStation truncates it to 20 bytes.
• To use the LinkStation as a member server in an NT domain, the LinkStation 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 LinkStation is a member server of an NT domain, you cannot connect as a guest user via AFP.
• When you change the user or group settings on the domain controller, these changes may not take effect
immediately on the LinkStation until it is rebooted.
• If your LinkStation is a member server in an NT domain and you change the authentication method to
“Workgroup”, the account on the domain controller will not be deleted automatically.
• If the LinkStation has joined a domain network, you cannot connect to it via FTP.
• Don’t disable the SMB protocol while an NT domain server is used for access restrictions. If you do, you will need
to enable SMB again and reconfigure the NT domain settings from scratch.
User Authentication with an External SMB Server
LinkStations on your network can be linked to an external authentication server for centralized management of
user accounts and passwords. The authentication server should be another Buffalo NAS device. Other external SMB
authentication servers are not supported.
Notes:
• Disable SMB2 before using external authentication.
• Access restrictions for local users and groups will still apply to shared folders if an external SMB server is used for
authentication.
• The procedure below contains methods to automatically register external users. You can also manually add
external users by converting them from local users. Refer to the “Converting Local Users into External Users”
section above for more details on converting local users.
1 From Advanced Settings, click [Network].
2 Click to the right of “Workgroup/Domain”.
3 Click [Edit].
37
Chapter 3 File Sharing
4 Select “Workgroup”, then click [Next].
5 Click [Yes].
6 Enter a workgroup name. Select “Authenticate local and external SMB server users” and enter the SMB server’s
IP address. You can also specify a server from another subnet.
7 If “Automatically register users who access LinkStation folders” is selected, users that access any of the
LinkStation’s folders will be automatically registered as external users. This process only applies to folders that
have access restrictions disabled. After new external users are added, disable this option to limit the number of
authenticated user accounts.
8 If “Restrict user registration to a single folder” is checked, the LinkStation will automatically create a read-
only shared folder. Enter the shared folder name. Users that access this specific folder will be automatically
registered as external users. If this setting is deselected at a later time, the LinkStation will automatically
remove the folder.
Note: Connect to the authentication folder via SMB, not FTP or AFP. Automatic user registration may not
work the first time if on macOS 10.8 (or later). If this occurs, try rebooting the LinkStation, then access the
authentication shared folder again.
38
Chapter 3 File Sharing
9 Click [OK] to save any changes. When saving changes to the external authentication server settings, you may
not convert all current local users to external users. If a local user is converted to an external user, their user
information (including passwords) will be removed from the NAS. External users cannot be reverted to local
users.
10 Click to the right of “Folder Setup”.
11 Click the shared folder that you want to set access restrictions for.
12 Click [Edit].
13 Enable “Access Restrictions”.
14 Click the [External Users] tab and select the level of access for each external user.
: Read and write : Read-only : No access
15 Click [OK].
Notes:
• Users that are automatically registered belong to the “hdusers” group. They can be added to other groups from
within group settings. Added users will be listed in “Users” > “External Users”. To delete a user that was registered
automatically, select that user and click [Delete External User].
• The most restrictive access settings will always apply. For example, if both read-only and read and write
permissions are given to a user, the user will have read-only access.
• To access access-limited shared folders from OS X 10.7, use AFP instead of SMB; under “LAN Protocol Support”,
check “AFP (Mac)” on the destination folders to use AFP and click [OK].
39
Chapter 3 File Sharing
• If access restrictions are set for users and groups from the authentication server, guest and anonymous
connections will not be possible with AFP connections.
• FTP connections do not support authentication with an external SMB server.
• If using a Windows PC for external authentication, the default Windows SMB security settings may need to be
changed. An easy way to do this is to run File Sharing Security Level Change Tool, available from this product’s
download page on the Buffalo website. This utility will let you easily change or restore your Windows security
settings to work with external authentication.
Chapter 4 Storage Management
RAID Modes
The LinkStation supports many types of RAID. The type of RAID arrays available for use depends on how many drives
are installed on your LinkStation.
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.
• After the RAID mode is changed (except when creating a RAID 0 array), the LinkStation performs a RAID scan that
will take about 10 hours per TB. File transfers are slower during this period. While the I17 message is displayed in
NAS Navigator2, do not turn off the LinkStation. If you do, the RAID scan will start over.
RAID 1
Combines two 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.
RAID 0
Combines two 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 LinkStation as individual drives. The usable space is equal to the total capacity
of all drives on the LinkStation. If any of the drives become damaged, then all data on that drive will be lost.
Working with RAID Arrays
To change RAID settings, navigate to [Drives] > [RAID] in Advanced Settings.
Using JBOD
With JBOD, each drive on the LinkStation is addressed separately. To put drives from an array into JBOD, follow the
procedure below.

3 Choose a RAID array.
4 Select a RAID mode and the drives to be used, then click [Create RAID Array].
Note: Normally, after a RAID array is created, it is “resynced”, which optimizes the array, making it more stable.
The resyncing process will take about one hour per terabyte of space in the array. File transfers will be slower
during this period, but the array will remain fully usable. The I17 message will also be displayed in NAS
Navigator2 during the resync. If you clear the “Resync after creating the RAID array” checkbox, the resyncing
process will be skipped. If the LinkStation is rebooted during the resyncing process, the resync will begin again
from the beginning.
5 The “Confirm Operation” screen will open. Enter the confirmation number, then click [OK].
6 Click [OK] when completed. Next, create a shared folder by referring to the “Adding a Shared Folder” section in
chapter 3.

Adding an External Drive
Connecting an External Drive
Your LinkStation features a USB port, and you can connect an external drive to this port. Once connected, it appears
as a shared folder on the LinkStation. Formatted drives are detected automatically. Unformatted drives should be
formatted in Settings.
After a USB drive is recognized, the LinkStation adds “usbdisk x” to the shared folder list, where “x” is the USB port to
which the drive is connected.
Compatibility
The following devices are supported by the LinkStation. Buffalo external USB drives are recommended but DUB and
DIU series drives are not supported.
• USB storage devices
• Card readers (except for card readers that can recognize two or more memory cards)
Supported file systems for external drives and the types of allowed access are listed below:
Ext3*XFS NTFS*exFAT*FAT32 HFS Plus*
Accessing via SMB R R/W R/W R/W R/W R
Using as a backup drive R/W R/W R/W R/W R/W R
Using for Direct Copy R/W R/W R/W R/W R/W R
R/W: Read and write, R: Read-only
*This cannot be formatted from Settings.
Make sure only one device is connected to a USB port on the LinkStation. Some external drives with automatic
power-on won’t turn on automatically when connected to the LinkStation. Use their manual power switch to turn
them on. Be sure to connect only one bus-powered drive at a time. If there is insufficient bus power for your USB
46
Chapter 4 Storage Management
drive, connect its AC adapter. Note that only the first partition of a connected USB drive is mounted. Additional
partitions are not recognized.
Dismounting Drives
If the LinkStation is powered on, dismount drives (internal and external) before unplugging them. You may
dismount the external drive using the function button, or dismount any drive from Settings. If the LinkStation is off,
then all drives are already dismounted and may be unplugged safely.
Note: If you unplug your external drives without dismounting them, Settings may still show “usbdisk” in the shared
folder list. Reboot your LinkStation to clear it.
Dismounting Using the Function Button
Press and hold down the function button for three seconds. The white function LED will go out as all attached USB
drives are dismounted. You may now unplug any USB drives safely.
Dismounting from Settings
Follow the procedure below to dismount a drive. To dismount a drive while using a mobile device, refer to the
“Dismounting USB Drives” section in chapter 9.
1 From Advanced Settings, click [Drives].
2 Click [Drives] to dismount an internal drive or [USB Drives] to dismount an external drive.

4 Click [Check]. You have the option of deleting information files from macOS during the check if desired.
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. Instead, refer to the “Erasing Data on the LinkStation 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.
1 From Advanced Settings, click [Drives].
2 Click [Drives] to format an internal drive or [USB Drives] to format an external drive.
49
Chapter 4 Storage Management
3 Select the drive or array to format, then click [Format Disk].

refresh the status by clicking [Rediscover Disk]. If the status doesn’t change, disconnect and reconnect the USB
drive.
4 Select a format type, then click [Format].
5 The “Confirm Operation” screen will open. Enter the confirmation number, then click [OK].
6 Depending on the size of your drive, the format may take several minutes or several hours to complete. The
power LED will flash during the format. Shared folders cannot be accessed during a format. Click [OK] when
completed.
Notes:
• Do not turn off the LinkStation or disconnect power to the LinkStation while formatting a drive.
• For drives that are 2.2 TB or larger, make sure that the “GPT Partition” checkbox is selected. If you accidentally
format a larger drive without GPT, disconnect and then reconnect it before reformatting with GPT.
50
Chapter 4 Storage Management
Erasing Data on the LinkStation 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 LinkStation will then be in the following
state:
• Both drives in JBOD
• An empty shared folder on each drive
• All settings returned to their default values
• All logs deleted
Follow the procedure below to completely and permanently erase all data from your LinkStation.
1 From Advanced Settings, click [Management].
2 Click to the right of “Restore/Erase”.
3 Click [Erase LinkStation].
4 The “Confirm Operation” screen will open. Enter the confirmation number, then click [OK].
5 All data on the LinkStation will be permanently erased.
Quotas
You can set a quota for each user or group as well as a threshold alert where you will receive an email notification if
the space used exceeds the configured threshold. To configure email notifications for the quota, refer to the “Email
Notification” section in chapter 8.
Notes:
• When using quotas, disable the recycle bin or empty the trash folder often. The limited space includes the space
used for trash.
• Quotas apply per drive or per array. If a quota is set to 1 GB, each array or drive can use a maximum of 1 GB.
• Quotas cannot be set for external drives connected to the LinkStation.
• If both user and group quotas are configured for a user, the most restrictive quota will always apply.

Drive Replacement
If a drive fails, an error message will be displayed in both NAS Navigator2 and Settings.
Notes:
• Do not replace a running drive while the LinkStation is turned on. Power down the LinkStation before changing
the drive. While the LinkStation is running, never unplug or remove drives without dismounting them first.
• If using the LS220DR LinkStation model, use a Buffalo OP-HDBN series drive as the replacement drive. For the
replacement drive of other LinkStation models, use a Buffalo OP-HDBST series drive. The replacement drive
should be the same size or larger as the original drive. If a larger drive is used, the extra space will not be usable in
a RAID array.
• If sending a defective drive to Buffalo for replacement, please keep the cartridge as Buffalo will only replace the
drive and not the cartridge.
• To avoid damaging the LinkStation with static electricity, ground yourself by touching something made of metal
before handling any sensitive electronic parts.
• After a drive is replaced, it will take about 30 minutes before normal file reading and writing operations are
restored. Settings may not be accessible during this period.
• Do not change the order of the drives on the LinkStation. For example, pulling out the drive in slot 1 and
replacing it with the drive in slot 2 may cause data to be corrupted or lost.
• If a new drive is not recognized after installing it, click [Rediscover Disk] in Settings.

/mnt/array1/share
/mnt/disk1/share
/mnt/usbdisk1
• Don’t use FTP to share files and folders with multibyte characters in their names with a Mac. Use an AFP or SMB
connection instead.
• If a file was created or copied using AFP, you may be unable to delete it using an FTP connection. If this occurs,
use an SMB or AFP connection instead to delete the file.
• For FTP connections, make sure that the total filename length including the folder path is 250 single-byte
characters or less.
Chapter 6 Backup
Backing Up Data on the LinkStation
You can back up the LinkStation folders to another shared folder on the same LinkStation, a connected USB drive, or
a shared folder on another Buffalo NAS device, either on the same network or on another network.
Backup Modes
The following types of backup are available from this LinkStation.
Normal Backup
All files in the source will be backed up to the destination. 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 LinkStation (excluding the “info” folder)
◦USB drive connected to the backup source LinkStation
◦Shared folder on another Buffalo NAS device*
• Folders available as backup destinations:
◦Shared folder on the backup source LinkStation (excluding the “info” folder)*
◦USB drive connected to the backup source LinkStation*
◦Shared folder on another Buffalo NAS device*,**
*The folder should have the “Backup” checkbox selected for “LAN Protocol Support” on the shared folder settings.
**You can select up to the second level of folders.
Overwrite (Incremental)
The first backup job runs like a normal backup. As each subsequent backup job runs, only files that have been
changed since the last normal 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 LinkStation (excluding the “info” folder)
◦USB drive connected to the backup source LinkStation
◦Shared folder on another Buffalo NAS device*
• Folders available as backup destinations:
◦Shared folder on the backup source LinkStation (excluding the “info” folder)*
◦USB drive connected to the backup source LinkStation*
◦Shared folder on another Buffalo NAS device*,**

Overwrite (Differential)
The first backup job runs like a normal backup. As each subsequent backup job runs, only files that have been
changed since the last normal 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 will be the same as the backup
source folder.
• Folders available as backup sources:
◦Shared folder on the backup source LinkStation (excluding the “info” folder)
◦USB drive connected to the backup source LinkStation
◦Shared folder on another Buffalo NAS device*
• Folders available as backup destinations:
◦Shared folder on the backup source LinkStation (excluding the “info” folder)*

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 and files using SSL/TLS for secure FTP communication. First, open a shared folder’s
settings and click [Edit]; under “LAN Protocol Support”, select the “FTP” checkbox and click [OK]. Afterwords, enable
SSL security in the setup screen for your FTP client. The procedure depends on the FTP client software.
SSL Keys
SSL keys are used during setup screen operations and FTP communication. SSL (Secure Socket Layer) is a type of
encryption system called public key encryption. Generally, SSL is managed by the two files below.
server.crt (SSL Certificates)
The LinkStation sends the file to a computer, and the computer uses it to perform encryption. The LinkStation
receives the encrypted data and uses server.key (the private key) 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 LinkStation’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. Disregard this message and continue.
server.key (SSL Private Key)
This file is used as a pair with server.crt (server certificate). This is required for decrypting the data that was
encrypted by the server certificate, and this is normally not revealed.
Note: The passphrase for the private key must be removed before importing to the LinkStation.
