●
A unique Sync ID is used to associate the replicated share or partition on the source
system with the share or partition that will receive the replicated data on the target
system.
●
You do not need to schedule or manually perform Directory/File or Cartridge Based
Replication through the remote management console. Instead, replication is triggered
when a file is closed or a period of time after it is modified (NAS shares), or when a tape
cartridge is unmounted (VTL partitions).
I
For CIFS shares, a file is replicated immediately after it is closed. For NFS
shares, a file is replicated after it has been idle (not accessed) for several
minutes.
●
After directories and files or cartridges are replicated using Directory/File or Cartridge
Based Replication, they are automatically recovered on the target system and are
immediately available for use. There is no need to first recover the share or partition to
access its data.
●
Deletions are automatically propagated from the source system to the target system in
order to free up space on the target. In addition, you can manually initiate a synchroni-
zation from the source system at any time. Synchronizing ensures that the contents of
the source share or partition are exactly the same as the target share or partition.
V
CAUTION!
Cartridge barcodes for all source systems that are replicating to the same target
must be unique.
I
If you delete a share configured for Directory/File Based Replication on the source
ETERNUS CS800, the share is
not
automatically deleted on the target ETERNUS
CS800. If you do not want to retain the share on the target ETERNUS CS800, you
can manually delete it.
OST Optimized Duplication
The ETERNUS CS800 can duplicate the data on an LSU (logical storage unit) to another
location using the OST optimized duplication (OST replication) feature supported by
Symantec NetBackup and Backup Exec. If you are using Symantec NetBackup 7.1 or
higher, you can configure an LSU for Automatic Image Replication.
For information about configuring and using OST optimized duplication, see the
ETERNUS
CS800 OST Guide.
