Changing RAID Modes  
RAID Arrays  
TS-XL, TS-XEL and TS-RXL series TeraStations default to RAID 5 mode (4 hard drives), TS-WXL/R1 series default to RAID  
1 mode, and TS-WXL/1D series default to Normal mode. The characteristics of each type of RAID are described below.  
If you change the RAID mode, all of the data on the hard drive is deleted. Always back up any important data before  
changing the RAID mode.  
Note:  
• In this document, “recovery” means putting the TeraStation back to the state it was in before the malfunction  
happened. It does not mean reading data from failed hard drives.  
• RAID 5 mode (4 hard drives) (Default for TS-XL, TS-XEL and TS-RXL)  
Note:  
TS-WXL/R1 and TS-WXL/1D TeraStations don’t support this mode, as they don’t have 4 hard drives.  
Uses 4 hard drives as one array. It generates parity during writes, so access speeds are slower than other RAID modes.  
Usable space is the sum of 3 hard drives’ space. If one hard drive in the array is damaged, you can recover data by  
replacing the hard drive. You cannot recover data if 2 or more drives are damaged.  
• RAID 5 mode (3 hard drives)  
Note:  
TS-WXL/R1 and TS-WXL/1D TeraStations don’t support this mode, as they don’t have 3 hard drives.  
Uses 3 hard drives as one array. It generates parity during writes, so access speeds are slower than other RAID  
modes. Usable space is the sum of 2 hard drives’ space. You can designate a 4th drive as a hot spare, which will boot  
automatically if one of the drives in the array fails. If one hard drive in the array is damaged, you can recover data by  
replacing the hard drive. You cannot recover data if 2 or more drives are damaged.  
• RAID 10 mode  
Note:  
TS-WXL/R1 and TS-WXL/1D TeraStations don’t support this mode, as they don’t have 4 hard drives  
RAID 10 combines 4 hard drives into a single array. Usable space is the sum of the capacity of 2 hard drives. Data is  
written quickly and access speed is faster than other RAID modes except for RAID 0. Since the same data is written to 2  
hard drives at the same time, if drive in a pair (1-2 or 3-4) is damaged, data can be recovered by replacing the damaged  
hard drive. If both 1-2 or 3-4 hard drives are damaged, you cannot recover data.  
TeraStation User Manual  
18  
 
• RAID 1 mode (Default for TS-WXL/R1)  
Uses 2 hard drives as one array. You can use up to 2 arrays on TS-XL, TS-XEL and TS-RXL Series. The space you can use  
is 1 hard drive’s space for each array. The same data is written to 2 drives at once. If a drive is damaged, data can be  
recovered by replacing the damaged hard disk. If both drives in an array are damaged, data cannot be restored. You  
can create an array and designate another drive as a hot spare (which will boot automatically when one of the hard  
drive fails) in TS-XL and TS-RXL TeraStations. You can use 2 drives to create a RAID 1 array, use anther drive as a hot  
spare, and use another as a regular drive, all at once.  
• RAID 0 mode  
This mode uses multiple hard drives as a single array. The disk space you can use is the total space of all hard drives  
used. This is the fastest of the TeraStation’s RAID modes. If any hard disks are damaged, you cannot recover data.  
• Normal Mode (Default for TS-WXL/1D)  
This mode uses the hard drives inside the TeraStation as individual hard disks. It is sometimes referred to as JBOD. The  
disk space you can use is the total space of all hard drives in the TeraStation. If a hard disk is damaged, you cannot  
recover data from that drive.  
Note:  
During a recovery, the TeraStation’s front LED display shows “RAID ARRAY* Resyncing” and file transfer speeds are  
slower than usual until the RAID array is rebuilt.

Configuring a backup job  
1 To create a backup job, navigate to [System] - [Backup] - [Back Jobs Setup] - [Create New Job] in the source  
TeraStation's Web Admin interface.  
Note: Up to 8 backup jobs can be configured.  
Select backup settings such as date and time to run.  
2
Note:  
Refer to page 131 for more on backup options.  
The following types of backup job may be selected:  
[Normal Backup]  
All files in the source will be backed up to the destination.  
[Overwrite Backup (Append Backup)]  
The first time the backup job runs is just like a normal backup. Each addditional time the backup job runs, if file  
A was added to and file B removed from the backup source, then file A is added to but file B is not removed from  
the backup destination. Over time, the backup destination folder will become larger than the backup source  
folder.  
[Overwrite Backup (Differential Backup)]  
The first time the backup job runs is just like a normal backup. Each addditional time the backup job runs, if file  
A was added to and file B removed from the backup source, then file A is added to and file B is removed from the  
backup destination. The backup destination folder is always the same as the backup source folder.  
The following types of folders may be used as either backup sources or backup destinations:  
• Shared folders on your TeraStation, including attached USB drives, but not including the info folder  
• Shared folders on a different TeraStation or LinkStation on the local network, but not USB drives attached to it  
• Shared folders of a TeraStation or LinkStation on a different network that has been selected manually by IP address,  
but not USB drives attached to it  
Notes:  
• Before using a folder for backup, navigate to [Shared Folders] in the Web Admin interface and check [Disk Backup]  
for [Shared Folder Support].  
• Subfolders of shared folders are not supported for backup.  
• To make a TeraStation or LinkStation that is on a different network available for use as a backup target, navigate to  
[System] - [Backup] - [View NAS Devices] in the source TeraStation’s Web Admin interface and add it by IP address.

The backup job is added to the list of backup jobs.  
Backup Notes:  
• You can register up to the second level of subfolders. However, folders with more than 80 bytes(UTF-8) in their names  
cannot be selected.  
Before they can be selected as backup target folders, folders on other TeraStations must be configured as backup  
destinations.  
To use a folder on an external hard drive as a backup target, you should format it with XFS, FAT or EXT3.  
• If you are using PC Power Management, your system will automatically boot 15 minutes before the backup job  
begins.  
• If your PC enters sleep mode just before a scheduled backup, the backup job may not have time to reboot the system  
before the backup job begins. If this happens, the backup job may fail.  
Source and target TeraStations should be configured with similar Jumbo Frame settings. If you are experiencing  
problems backing up one TeraStation to another, try setting the frame size for both to the default (1518 bytes).  
• If you change formatting or RAID array settings, previously created backup jobs may no longer run correctly. Delete  
the old backup jobs and create new backup jobs for the new share(s).  
Backups on EXT3 formatted USB disks can be read from a Windows PC with the provided Buffalo EXT3 reader  
software.  
TeraStation User Manual  
35  
Restrictions regarding to Backup  
When performing backup to USB hard disk (FAT32 format) with [Overwrite Backup (Differential Backup)] option,  
it may overwrite even though there are no difference in data. This is because of the specification of FAT 32. If the  
second of the date when the file created is an odd number, Overwriting backup is performed every time regardless of  
the differences in data.  
If you are using Jumbo Frame and backup data on TeraStation/LinkStation to another TeraStation/LinkStation, set  
the Ethernet frame size of those 2 TeraStation/LinkStation to the closest value. If Ethernet frame sizes of these are  
significantly different, the backup job may not be properly performed. In such a case, select the default frame size  
(1518 bytes).  
When backing up data by using Web Admin interface, if a file name or folder name to backup contains multi-byte  
characters, a file/folder name of a log file may not be output correctly.  
If you change settings for formatting or RAID array after setting for backup, you must change the settings for backup.  
If there is no shared folder at the destination, an error message will be displayed.  
TeraStation User Manual  
36  
Replication  
Replication will mirror data on your TeraStation to a second TeraStation. An exact duplicate of a data share on the first  
TeraStation is copied to the second TeraStation virtually simultaneously. To configure Replication, use an Ethernet cable  
to connect LAN Port 2 on the first TeraStation to LAN Port 2 on the second TeraStation. The first TeraStation should be  
connected to the local Network by LAN Port 1.  
Notes:  
If the first TeraStation goes down, you can switch to the second TeraStation by moving the main Ethernet cable from  
the first TeraStation to the second TeraStation’s LAN Port 1.  
Replication copies data only, not users or settings. To back up users, groups, and passwords from a TeraStation, use the  
NS-SHFT utility.  
If a backup password is set for a share, then that share cannot be selected as a backup target for replication.  
Replication copies data from the source folder to a target folder. Please note that any data in the target folder that is  
not in the backup source folder will be deleted.  
Only folders on TeraStations which support Replication (TS-XL, TS-XEL, TS-WXL, TS-RXL, TS-HTGL, TS-RHTGL. etc.) can  
be selected as replication source folders or target folders.  
Up to 64 shares can be selected for replication.  
Only data written by SMB and CIFS (Windows) and AFP, NFS, SFTP, FTP, and FTPS (Apple) can be mirrored by  
replication.  
Replication transfers files asynchronously. It may take time to transfer files depending on the network environment or  
status of the TeraStation.  
Replication will retry file transfers if they fail because of a network problem. If the retry fails, the TeraStation’s Error LED  
will light and an alarm will sound. To repair, fix the network problem, then, in the Web Admin interface, navigate to  
[System] - [Backup] - [Replication] and click [Resynchronize].  
Do not set multiple Backup Targets for one Backup Source. Multiple transfer processes for Replications will run, and  
system performance will be adversely affected.  
Do not replicate a share that is the target of Time Machine backups by Mac OS X.  
System performance may be degraded if Mac OS X writes to the replication source folder with an AFP connection. If  
this occurs, connect via SMB for better performance.  
When replicating to a USB drive, a folder which has the same name as the backup source will be created on the USB  
drive. If the same folder name already exists on the USB drive, any files in that folder will be deleted.  
External hard drives formatted with FAT 16 or FAT 32 should not be used with replication. For best results with the  
TeraStation, format your external USB hard drives with XFS or EXT3.  
NFS is set to the [Kernel mode], files or folders written by NFS protocol are not transmitted to the replication  
destination. To change NFS settings from the [Kernel mode] to the [User mode], select [Network] - [NFS] - [NFS Service]  
on the Web Admin interface.

Technical Restrictions  
Windows does not support some characters that OS X and the TeraStation allow. So, if you create a filename on a Mac  
with any of the following characters, it will not display correctly on a Windows computer. With Mac OS X 10.2 or later,  
you may have to connect to the TeraStation via AFP in order to display or copy any of the following characters: ? [ ] / ¥  
= + < > ; : ” , | *  
Do not use any of the following words as a Username or Group Name: root, bin, daemon, sys, adm, tty, disk, lp, sync,  
shutdown, halt, operator, nobody, mail, news, uucp, ftp, kmem, utmp, shadow, users, nogroup, all, none, hdusers,  
admin, guest, man, www, sshd, administrator, ftpuser, apache, mysql.  
Do not use any of the following words as a shared folder name: info, spool, usbdisk1, usbdisk2, usbdisk3, usbdisk4,  
lost+found, global, printers, homes, lp, auth, ram, disk1, disk2, disk3, disk4, array1, array2.  
When using multi-byte characters (such as Japanese), make folder and file names with 80 bytes or less. Total  
pathlength is limited to 1024 bytes. You may not be able to copy a folder or file whose name is more than 80 bytes  
characters long, or whose pathname is more than 1024 bytes total.  
• You cannot set hidden or read-only attributes to folders or files on a TeraStation from Windows. To set an attribute for  
a share on the TeraStation, use the Web Admin interface. In [Shared Folders] - [Folder Setup], click the shared folder  
you want to configure. Select [Read Only] or [Read & Write] from [Shared Folder Attributes], and [Hide Share] from  
[Folder Mode (SMB Only)].  
If local characters aren’t displayed properly in a Shared Folder or Workgroup name, use alphabetical character.  
If you access a shared folder from a Macintosh computer, information files for Macintosh may be automatically  
generated. Do not delete these files from a Windows computer. Otherwise, you may no longer access folders from  
Macintosh.  
A volume name mounted by [Finder] from Mac OS X 10.3.9 may be corrupted when connected via SMB. File names  
and data should be fine.  
On Mac OS X 10.5 - 10.5.6, you cannot search by Spotlight while connected via AFP. In such a case, use SMB  
connection or use Mac OS X 10.5.7 or later.  
• TeraStation belongs to the default zone specified by an AppleShare Server. You cannot specify a zone.  
Date and Time stamp information stored on a TeraStation’s hard disk or a USB hard disk connected to the TeraStation  
may be updated by an attached OS, and its accuracy cannot be guaranteed.  
If you display size of hard drives through the Web Admin interface, it will show a larger value than that shown by  
Windows’ drive properties.  
If you change a TeraStation’s settings or add a USB hard drive while transferring files, the file transfer may be aborted.  
Copying files to TeraStation is protected by the Journaling File System. However, if power is suddenly disconnected in  
the middle of a file copy, the following events may occur:  
- Data configured (TeraStation, User or Group names) may be lost.  
- The copied file may be incomplete and it may not be deleted. In such a case, restart TeraStation and delete the file,  
and try copying the file again.  
Although you format TeraStation’s hard disk, [Percent Used] or [Amount Used] in the Web Admin interface will not  
show 0 (zero). This is because some space is used for the system.  
Set the TeraStation’s username and password the same as the user’s username and password for logging into the

Changing the IP Address  
Normally, the TeraStation’s IP address is set automatically from a DHCP server on your network. If you prefer, you can  
set it manually. To change the TeraStation’s IP address settings, your computer should be connected to the same router  
(subnet) as the TeraStation and should be running NAS Navigator2 (included on your TeraNavigator CD).  
1 For a PC, double-click the [NAS Navigator2] icon on your Desktop. For a Mac, click the [NAS Navigator2] icon in  
the Doc. NAS Navigator2 will launch.  
2 For a PC, right-click your TeraStation and choose [Properties]. Select [IP Settings]. For a Mac, hold the control key  
and click your TeraStation's icon, then choose [Configure] - [IP Address].  
Uncheck [Obtain IP address automatically via DHCP.]. Enter the desired [IP  
Address] and [Subnet Mask]. Click [OK], or [Apply] if you’re using a Mac.

Notes:  
• To benefit from using Jumbo Frame in the TeraStation, your router/switch/hub should support Jumbo Frame.  
• To use Jumbo Frame (4102/7422/9694 bytes), your computer’s NICs and all switches, hubs, and routers on the  
transmission route need to support Jumbo Frame. If any device on the route doesn’t support Jumbo Frame, use  
standard transmission (1518 bytes) instead.  
• If you are using Jumbo Frame and back up data from a LinkStation/TeraStation to another LinkStation/TeraStation, set  
the Ethernet frame sizes of the LinkStations/TeraStations to the same settings (or the closest available). If the Ethernet  
frame sizes are significantly different, the backup job may fail. If you have problems with backup jobs, select the  
default frame size (1518 bytes).

[Broadcast policy]:  
Sets a broadcast policy for fault tolerance.  
[Dynamic link aggregation] (*2):  
Sets an IEEE 802.3ad dynamic link aggregation policy.  
[Adaptive transmit load balancing (TLB)]:  
Sets a Transmit Load Balancing (TLB) policy for fault tolerance and load balancing  
*1 Your switch must support this. Configure the two ports on the switch in advance. Refer to your switch’s manual for  
instructions on configuring it.  
*2 Your switch must support this. Enable LACP (Link Aggregation Control Protocol) in the switch in advance. Refer to  
your switch’s manual for instructions on configuring it.

DFS (Distributed File System)  
Distributed File System (or DFS) combines shares on the network server together into one tree.  
In the following example, when the client computer addresses //tera/share/backup, it’s actually looking at files located  
at //pc_srv/backup. This is transparent to the user of the client computer. If the TeraStation is configured to address  
multiple DFS shares, then shares on other devices could be addressed as native shares on the TeraStation. For example,  
//tera/share/share might actually address data located at //link/share.

To access the TeraStation with an FTP client  
Configure your FTP client software with the following settings:  
Host Name  
Username  
Password  
Port  
IP address of the TeraStation.  
Username registered on the TeraStation  
Password registered to the TeraStation  
21  
Example ftp://192.168.11.150/  
• You cannot write by FTP if the shared folder is set to read-only on the TeraStation.  
Access restrictions are applied based on the settings in the TeraStation. The restrictions aren’t displayed for users  
without permissions for the share.  
To access your FTP share from outside of your network, you may need to configure your router and firewall. Consult  
your router documentation for more information.  
Shared folders appear as follows when connected by FTP:  
- disk1 share  
- usbdisk1  
- info  
The internal hard drive of the TeraStation is displayed as disk1, and a USB hard drive (optional) will be displayed as  
usbdisk1.  
”usbdisk1” is not displayed when the USB hard drive is not connected, or if access is restricted.  
Accessing the TeraStation with an Anonymous user:  
To allow anonymous access to your FTP share, disable access restrictions on the FTP share. Configure your FTP client as  
follows:  
Host Name  
Username  
Password  
Port  
IP address of the TeraStation  
anonymous  
any set of characters  
21  
Example ftp://192.168.11.150/  
To make your FTP share available from outside your network, you will need to configure your router and firewall.  
Consult your router’s documentation for information on how to allow FTP traffic.  
• If the TeraStation joins a domain, anonymous users cannot access it.  
Folders created or copied via an AFP connection may not be deleted from the AFP connection. This is because an  
automatically generated “.AppleDouble” folder begins with a dot. To delete these files, use an SMB connection.  
Do not exceed 250 bytes for a file/folder name including directory path when you are creating it by using an FTP  
connection. Otherwise, you cannot view or delete it in Explorer or other applications.

Accessing from a NFS Client  
Use the following procedure configure the TeraStation for access from UNIX with NFS.  
Note: This section is for information only. Unix and NFS are not supported by Buffalo. If you choose to configure your  
TeraStation this way, it does not void your warranty, but you are on your own for tech support.  
1 In the Web Admin interface, select [Network] - [NFS] - [NFS Service], and click [Modify Settings].  
1 Click [Enable].  
2 Click [Save].  
2
Note:  
• If you use a public folder of the TeraStation set by NFS as a hard drive for VMware ESX/ESXi, it is required to set  
[NFS Mode] to [Kernel mode] in order to use it (It is set to [User mode] by default).  
To set access restrictions by IP addresses, specify a [Network Address] and [Subnet Mask] from the screen  
above.  
(e.g.) To allow access from a client with the IP address 192.168.11.xxx:  
[Network Address]:  
[Subnet Mask]:  
192.168.11.0  
255.255.255.0  
xxx can be 1 to 254. Enter 0 (zero) for the [Network Address].  
(e.g.) To allow access from a client with the IP address 192.168.xxx.xxx:  
[Network Address]:  
[Subnet Mask]:  
192.168.0.0  
255.255.255.0

10 Examples of commands to access a folder on the TeraStation from the NFS client:  
From Linux:  
mount -t nfs <IP Address>:<NFS public path for the TeraStation><the mounting point on the local computer>  
(e.g.) mkdir /mnt/tsxl  
mount -t nfs 192.168.11.10:/mnt/array1/share /mnt/tsxl  
In this example, TeraStation’s IP address is “192.168.11.10”, NFS publishing path is “/mnt/array1/share”,  
and a mount point on the local computer is “/mnt/tsxl”.  
From Windows Services for Unix 3.5:  
mount <IP Address>:<NFS publishing path for the TeraStation> <a network drive’s letter (an error occurs if not  
available)>  
(e.g.) mount 192.168.11.10:/mnt/array1/share z:  
In this example, TeraStation’s IP address is “192.168.11.10”, NFS publishing path is “/mnt/array1/share”,  
and a network drive letter is “z”.  
From Solaris10:  
mount -<F nfs IP Address>:<NFS publishing path for the TeraStation><the mounting point on the local  
computer>  
(e.g.) mkdir /mnt/tsxl  
mount -F nfs 192.168.11.10:/mnt/array1/share /mnt/tsxl  
In this example, TeraStation’s IP address is “192.168.11.10”, NFS publishing path is “/mnt/array1/share”,  
and a mount point on the local computer is “/mnt/tsxl”.  
Notes:  
• Settings on the NFS Client will be applied to file access. However, if you write on root, uid and gid for all will  
be 99.  
• You cannot unify the uid and gid for user management on the TeraStation and for the users on NFS clients.  
• Root (admin) rights are required to perform the mount operation.  
• If you mount as root for other users, each user will need access rights for the mount point.  
You’ve completed the steps to access the TeraStation via NFS.

Encrypting Data Transmission  
Encrypting Data from the Web Admin interface  
Access https://<TeraStation’s IP address> instead of http://... to encrypt all data from the Web Admin interface.  
Note:  
Your computer may display “there is a problem with this site’s security”, but you may ignore this message and work  
normally.  
Encrypting FTP Transfer Data  
First, in the Web Admin interface, navigate to [Shared Folder Support] - [Ftp]. Check the box by each shared folder to  
encrypt data transfers.  
Enable SSL security in your FTP client to encrypt login passwords and files by using SSL/TLS for FTP communication.  
Examples: In FileZilla’s settings, select [FTP over TLS (explicit encryption)] for the server type. For Smart FTP, select [FTP  
over SSL explicit] in the settings.  
Notes:  
• Encryption processes may seriously reduce data transfer speeds. Your transfers may be as much as 10 times slower  
when using encryption.  
• Depending on your computer’s security settings, the message “there is a problem with this site’s security” may be  
displayed, but you may ignore this message and work normally.  
TeraStation User Manual

SSL Key  
Note:  
This procedure is described for network administrators and advanced users. Do not try to configure this unless you  
know exactly what you’re doing.  
You may use encrypted keys such as https and FTPS for the Web Admin interface operations and FTP connections.  
SSL (Secure Socket Layer) is a public key encryption method. SSL operation is managed by 2 files:  
(1) server.crt (SSL Certificate)  
TeraStation will send this certificate to other computers, which will use it as a key for encryption. The TeraStation will  
then receive encrypted data and use the server.key (SSL Key) to decrypt them.  
This key includes Server Certificate on SSL, and your PC may decide if the certificate can be trusted or not. Your  
computer may display the message “There is a problem with the site’s security certificate.”  
(2) server.key (SSL Key)  
This is used to decrypt data encrypted by the server certificate.  
Note:  
Prepare the decrypted passphrase for the server.key (SSL Key).  
Updating SSL Key  
To update a server certificate and a private key for SSL, follow the procedure below.  
1 In the Web Admin interface, navigate to [Network] - [Settings] - [Network Services] - [Add/Edit SSL Key].  
2 Register server.key for [SSL Key] and server.crt for [SSL Certificate], then click [Import].  
Note:  
Save SSL key files (server.key and server.crt) on the root of Drive C. They should not be saved in a folder or path whose  
name includes multi-byte or special characters.  
You’ve updated the SSL key.  
Notes:  
• The SSL key should not be password protected.  
• If the Web Admin interface isn’t accessible after updating, initialize the TeraStation.  
• Updating the firmware will initialize an SSL key.

Wake on LAN  
The TeraStation supports Wake on LAN, which allows it to be turned on remotely.  
Before using Wake on LAN, enable it as described below.  
In the Web Admin interface, navigate to [Network] - [Settings] - [IP Address Settings]. Click [Modify Settings].  
1
1 Click [Enable] for [Wake on LAN].  
2
2 Click [Save].  
Wake on LAN is now enabled. As long as it is connected to power and the network, you can turn on the TeraStation re-  
motely. To turn the TeraStation on remotely, send a Wake on LAN packet to the TeraStation on UDP port 2304.  
Notes:  
TS-XEL series TeraStations do not support Wake on LAN.  
• After receiving the Wake on LAN packet, the TeraStation may take approximately five minutes to be ready to use.  
• After power is restored from a power outage, wait five minutes before sending a Wake on LAN packet to the TeraSta-  
tion.  
• To use Wake on LAN, you’ll need Wake on LAN software such as AMD’s Magic Packet utility. The TeraStation does not  
include Wake on LAN software.  
• The TeraStation does not support using Wake on LAN and port trunking at the same time. You may use either feature,  
but not both at the same time.  
• On the local network, Wake on LAN packets may be sent to port 2304 on either of the TeraStation’s LAN ports. If the  
TeraStation is connected to a Buffalo wireless router configured for remote access, then it may be turned on from out-  
side the local network (from the WAN side). To use this feature, the Buffalo router must be connected to LAN Port 1 only  
on the TeraStation. The TeraStation does not support remote WAN-side Wake on LAN if LAN Port 2 is connected to the  
router.

Password to  
Search  
Enter this password when you want to specify the shared folders on another TeraStation  
via the network as a backup destination. Enter the password to search for Backup which is  
set for the shared folders of another TeraStation. If you do not enter it, you cannot backup  
to the shared folders for which the authentication password has been set.  
* Only enter a single password for [Search for Backup Destination by Password].  
* The shared folder with different [ Remote backup password] cannot be set as a backup  
destination as well.  
* Searching backup destination shared folder by entering [Search for Backup Destination  
by Password] is only available for TeraStation other than the backup source.  
Steps for Setup  
1. On the Web Admin interface of the backup destination, set [Remote backup password]  
for each shared folder.  
2. Set the same password for [Remote backup password] of a shared folder you want to  
display as a backup destination as [Search for Backup Destination by Password] when  
you configure backup for the backup source TeraStation.  
3. Configure backup at the TeraStation which is the backup source.  
Select the shared folders of the backup destination from followings.*  
• Shared folders in the TeraStation which is the backup source.  
• The USB hard drive connected to the TeraStation which is the backup source.  
• A shared folder for which [Remote backup password] is not set in the TeraStation  
which is the backup destination.

tor2, or Easy Backup are included. When you want to read the manual on your computer in the network, install the utili-  
ties when you want.  
If You cannot Setup:  
The following list contains the typical symptoms and causes when TeraStation cannot be found on NAS Navigator2 or  
you cannot display the Web Admin interface.  
Cause 1 Cables are not connected properly.  
The hard drive is not physically connected or may have the bad connection. Reconnect the AC cable and the LAN cable  
and restart your computer and the TeraStation.  
Cause 2 The firewall is enabled, or software running in the background is installed.  
Disable the firewall or uninstall software which enables the firewall, and try to search for the TeraStation again.  
Cause 3. Both wireless and Ethernet adapter are enabled.  
Disable any adapters other than the LAN adapter to connect to the TeraStation.  
Cause 4 The defective LAN cable or the connection is not stable.  
Change a port on the hub to connect or replace the LAN cable.  
Cause 5 Your LAN board, card, or adapter is malfunctioning.  
Replace a LAN board, card, or adapter.  
Cause 6. The LAN board you are using or the transfer mode of the hub is not set.  
Change the LAN board, or change the transfer mode to [10M half-duplex] or [100M half-duplex].  
Some LAN boards and hubs may not be connected to the network properly if the transfer mode is set to [Auto Negotia-  
tion].  
Cause 7 There is a network bridge.  
If any network bridge which is not used, delete them.  
Cause 8 You are searching from a different network.  
You cannot search for the TeraStation over network segments. Connect the TeraStation to the same segment as the com-  
puter you use for search.  
Cause 9 TCP/IP does not work properly.
