• 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 synchronization 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.
Caution: Cartridge barcodes for all source systems that are
replicating to the same target must be unique.
Note: If you delete a share configured for Directory/File Based
Replication on the source DXi, the share is
not
automatically
deleted on the target DXi. If you do not want to retain the
share on the target DXi, you can manually delete it.
OST Optimized
Duplication
The DXi8500 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
and Automatic Image Replication, see Replicating OST Data on
page 316.
