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 Series and
so on) 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 the
replication function.
• Replication transfers files asynchronously. It may take time to transfer files depending on the network environment or
status of TeraStation operations.
• 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 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 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 drive with XFS or EXT3.
