Chapter 3 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 9

TeraStation User Manual 10

• 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 le transfer speeds are

slower than usual until the RAID array is rebuilt.

You can back up folders on the TeraStation to any of the following destinations:

Another TeraStation (instructions on pages 23, 24, and 25)• A dierent folder on the same TeraStation (instructions on pages 23 and 25)•

A USB hard drive connected to the TeraStation (instructions on page 25)•

• Set up Destination for Backup

Before backing up to a TeraStation, you must congure a folder on the TeraStaion as a backup destination.

In the TeraStation’s Web Admin, click [Shared Folders] - [Folder Setup].

Choose the folder you want to set as a backup destination.

Check [Disk Backup] from Shared Folder Support.

Optional: To congure a password for backup jobs to this share, enter it in

the [Remote backup password] eld. If you do not want to set a

password, do not enter anything.

Click [Save] at the bottom of the screen.4

Backing up to another TeraStation on the local network

If the target TeraStation is congured with a password for backup, you can nd it on the network by searching for the password.

In the target TeraStation’s Web Admin, navigate to1 [System] – [Backup].

Under [Search for Backup Destination by Password], click [Modify Settings].2

Enter a password and click [Save].

Now, you can easily nd this target TeraStation when conguring backup

jobs on a source TeraStation.

Backing up to a TeraStation on another network which is connected by a VPN

You can back up to a TeraStation on another network as long as the two networks are connected by a VPN. Follow the procedure below to enter IP address of the target TeraStation.

In the source TeraStation’s Web Admin, c1 lick [System] – [Backup] - [View NAS Devices].

Under [O Subnet TeraStation], enter the IP address of the target TeraStation and click [Add].

If you meet the following conditions, then you don’t have to congure the settings described above:

Not setting a password for backup on the target TeraStation.• Source TeraStation and target TeraStation are on the same network.•

Instead, just turn to the next page and congure a backup job

TeraStation User Manual 25

Conguring a backup job

To create a backup job, navigate to [System] - [Backup] - [Back Jobs Setup] - [Create New Job] in the source 1

TeraStation's Web Admin.

Note: Up to 8 backup jobs can be congured.

Note:

The following types of backup job may be selected:

Normal Backup

All les in the source will be backed up to the destination.

Overwrite Backup (Append Backup)

The rst time the backup job runs is just like a normal backup. Each addditional time the backup job runs, if le A was added to and le B removed from the backup source, then le A is added to but le B is not removed from

the backup destination. Over time, the backup destination folder will become larger than the backup source folder.

Overwrite Backup (Dierential Backup)

backup destination. The backup destination folder is always the same as the backup source folder.

Select backup settings such as date and time to run.

Note:

Refer to page 125 for more on backup options.

Click [Backup Folders] - [Add].

Select Backup source and Backup destination folders. 1

Click [Add].2

Click [Apply].

The backup job is added to the list of backup jobs.

TeraStation User Manual 26

Backup Notes:

Subfolders may be selected, but not subfolders of subfolders. Folders with more than 80 characters in their total path •

may not be selected.

Before they can be selected as backup target folders, folders on other TeraStations must be congured 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.

S• ource and target TeraStations should be congured 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 Bualo EXT3 reader software.•

TeraStation User Manual 27

Restrictions regarding to Backup

When performing backup to USB hard disk (FAT32 format) with Overwrite Backup (Dierential) option, it may •

overwrite even though there are no dierence in data. This is because of the specication of FAT 32. If the second of the date when the le created is an odd number, Overwriting backup is performed every time regardless of the dierences in data.

If you are using Jumbo Frame and backup data on TeraStation/TeraStation to another TeraStation/TeraStation, set • the Ethernet frame size of those 2 TeraStation/TeraStation to the closest value. If Ethernet frame sizes of these are

signicantly dierent, 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 TeraStation’s Web Admin screen, if a le name or folder name to backup contains 2 •

bytes characters, a le/folder name of a log le 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 28

Replication

Replication will mirror data on your TeraStation to a second TeraStation. An exact duplicate of a data share on the rst TeraStation is copied to the second TeraStation virtually simultaneously. To congure Replication, use an Ethernet cable to connect LAN port 2 on the rst TeraStation to LAN Port 2 on the second TeraStation. The rst TeraStation should be connected to the local Network by LAN Port 1.

Notes:

• If the rst TeraStation goes down, you can switch to the second TeraStation by moving the main Ethernet cable from

the rst 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 les asynchronously. It may take time to transfer les depending on the network environment or

status of the TeraStation.

• Replication will retry le 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, x the network problem, then, in the TeraStation’s Web Admin, 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 aected.

• 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 les 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.
