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.

|
• 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
•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
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.
