Veritas Storage Foundation™ for Windows FlashSnap Option was formerly known as Volume Manager (VM). Before you can use the Veritas Storage Foundation for Windows FlashSnap option to back up volumes, you must use Veritas Enterprise Administrator (VEA) to snap-start the volumes. You must purchase VEA separately.
See Using Snap Start on a Veritas Storage Foundation volume.
If the computer on which you are running a backup using the Advanced Open File Option is in an environment with the Central Admin Server Option and the Veritas Cluster Server installed, and if failover occurs to a Veritas Cluster Service node, you must manually clean up the snapshots before restarting the backup on the failover node. Refer to the VSFW documentation for details.
When the Veritas Storage Foundation for Windows FlashSnap Option is used for AOFO backups, the SnapBack of the volume is done asynchronously since SnapBack can take a long time (depending on the size of the volume snapped and the changes that may have occurred during the backup). Rather than hold the job completion for the length of the time this operation may take, the job will instead Complete with Success (if no other error occurs). Use the VERITAS Enterprise Administrator to verify that the re-synchronization completed.
In rare cases, it is possible that the SnapBack fails and a broken mirror results. If this occurs, the next FlashSnap job submitted for the same volume may also fail, with the error Volume cannot be snapped or Volume has not been Snap-started or is not a dynamic volume. The job is logged as Completed with Exceptions. Use the VERITAS Enterprise Administrator to verify why the SnapBack did not complete and then correct the error.
