Select the shared folder that will be the replication target, then click [OK].
Notes:
• Only the shared folders of TeraStation models that support replication can be selected. For details on supported
models, see www.buffalotech.com.
• Replication can be specified for individual folders. A maximum of 64 shared folders can be specified.
• Before replication, refer to "Preparing a Backup Location". Under [LAN Protocol Support], check [Backup] for the
target folder for replication.
• Shared folders with a backup password set cannot be selected as replication targets.
• Replication source data is copied using a differential overwrite to the replication target folder. Please note that
any data that is not in the replication source will be overwritten.

You can now confi gure Replication.
Restrictions
The restrictions described here assume that the latest fi rmware version is installed in the TeraStation. The latest fi rmware
can be downloaded from the Buff alo Technology web site.
• Only data written by SMB and CIFS (Windows) and AFP, NFS, SFTP, FTP, and FTPS (Apple) can be mirrored by replica-
tion.
• Replication transfers fi les asynchronously. It may take time to transfer fi les depending on the network environment
or status of the TeraStation.
• Replication will retry fi le transfers if they fail due to a temporary disconnection in the network. If the retry fails, an
error will occur. The error LED on the front of the TeraStation will glow red and an alarm will sound. To repair, fi x the
network problem, then navigate to [Backup] -
next to [Replication] - [Resync] in the Web Admin interface.
Click [Resync] to reset the number of unreplicated data fi les (fi les that are not backed up to the replication target) to 0.
•
System performance may become slow when accessing a folder that was set as the replication source.
• Do not set multiple replication targets for one replication source. Multiple transfer processes for replication will run,
and system performance will be adversely aff ected.
•
A large number of fi les cannot be continuously written to the replication source folder over a long period of time.
