Do not replicate a share that is the target of Time Machine backups by Mac OS X.
• Cascade settings are not possible in replication. In other words, usage is not possible where fi les transferred to the
replication target are further replicated to another location.
•
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.
• For best results, drives connected to the TeraStation should be formatted with XFS or EXT3. If a drive is instead for-
matted with FAT32 or FAT16, the following limitations may apply. Files larger than 2 GB cannot be backed up to a
FAT16 drive, and fi les larger than 4 GB cannot be backed up to a FAT32 drive. Errors may occur and backup jobs may
stop before fi nishing. If the second of the date when a fi le was created is an odd number, overwrite-diff erential back-
ups may overwrite FAT32 drives even if there is no diff erence in the data.
• If the data being backed up contains fi les from Mac OS X such as ".DS_Store", the fi le names may include characters
that cannot be written to FAT16 or FAT32 drives. This will cause errors and the replication may stop before fi nishing.
• If NFS is used in kernel mode, fi les or folders written by NFS are not transmitted to the replication destination. To
change NFS from kernel mode to user mode, select [File Sharing] -
next to [NFS] - [Edit] in the Web Admin in-
terface.
•
If the fi rmware for the replication source and replication target is not the latest version, in certain cases, shared fold-
ers with folder names that are 20 bytes or more cannot be selected. You can download the latest version of the fi rm-
ware for your TeraStation from www.buff alotech.com. This can sometimes fi x this problem.
Replication Folders
Folders that can be selected as the source and destination for replication are described below.
Folders that can be selected as the replication sources:
•
Shared folders on the TeraStation from which replication is confi gured (except for the "info" folder). This includes USB
drives.
Folders that can be selected as destinations for replication:
• Shared folders on the TeraStation where the replication job is confi gured (except for the "info" folder). This includes
USB drives.
*1
•
Shared folders on another LinkStation or TeraStation on the same network subnet (not including USB drives).
*1, *2
• Shared folders of LinkStations or TeraStations whose IP addresses were entered manually at [Backup] -
next
to [Backup] - [List of LinkStations and TeraStations] in the TeraStation's Web Admin interface.
*1, *2
*1 In [Shared Folders] - [Shared Folder Support], select [Disk Backup]. Subfolders within the main shared folder are not
backed up.
*2 Shared folders with passwords confi gured in [Shared Folders] - [Remote backup password] cannot be selected as
destinations for replication.
Failover
If your system confi guration includes another TeraStation, failover can be set to automatically copy fi les from the failover
source TeraStation (main TeraStation) to the failover target TeraStation (backup TeraStation) so that the main TeraStation
and backup TeraStation have the same folder confi guration (there may be a time lag in data synchronization due to the
time it takes to write data to the backup TeraStation).
If a problem occurs in the main TeraStation so that it can no longer be accessed, operation is automatically switched to
