Synchronizing a Share or Partition
Synchronize a NAS share or VTL partition to synchronize its contents with the corresponding share or
partition on the target systems. To synchronize a share or partition, it must be configured for Directory/File or
Cartridge Based Replication (see Configuring Directory/File or Cartridge Based Replication on page 134).
Synchronizing a share or partition ensures that the contents of the source share or partition are the same as
the target share or partition. The synchronization verifies that the same files or cartridges exist in both
locations, and that no additional files or cartridges exist in either location.
You should perform a synchronization in any of the following situations:
l When Directory/File or Cartridge Based Replication is first enabled for a share or partition.
l If a Directory/File or Cartridge Based Replication job fails.
l If Directory/File or Cartridge Based Replication is disabled for a time and then is re-enabled.
Manually performing a synchronization is not necessary except in the cases described above. When
synchronization is manually initiated for a share or partition, the replication queue for that share or partition is
cleared. All file write and delete requests are queued after the synchronization, and they are not processed
until the synchronization is complete. This can cause replication to appear to be slow, especially for a share
or partition that is frequently accessed.
Caution: Before synchronizing a share or partition, make sure all media are unmounted and there are
no active backup jobs to the share or partition. (After the synchronization reaches the Replicating
state, backup jobs are allowed.)
Additional Information
l Even when replication is paused, the system continues to queue Directory/File or Cartridge Based
Replication operations. Each time an operation is queued, the system logs an administration alert that
reports the total number of queued Directory/File or Cartridge Based Replication requests.
l If a synchronization fails, make sure the target share or partition is unlocked (see Configuring a Target
Share for Directory/File Based Replication or Configuring a Target Partition for Cartridge Based
Replication).
To synchronize a share or partition:
1. Select the share or partition to synchronize.
If multiple targets are configured, click the arrow next to the share or partition to display all targets, and
then select the desired target.
2. Click Synchronize Now.
The status of the synchronization job displays in the Job Status column.
