VSS-aware databases are auto-enabled and cannot be turned off. VSS lets
administrators create a shadow copy backup of volumes on a server. The shadow
copy includes all files and includes open files.
When it creates a recovery point, Symantec System Recovery alerts the Volume
Shadow Copy Service. VSS then puts the VSS-aware databases into a temporary
sleep state. While in this quiesced state, the database continues to write to
transaction logs during the backup. After the databases are quiesced, Symantec
System Recovery takes the snapshot. VSS is then notified that a snapshot is
completed. The databases are awakened, and the transaction logs continue to be
committed to the database. Meanwhile, the recovery point is created. The databases
are only quiesced for the snapshot, and are active for the rest of the recovery
point creation.
Symantec System Recovery supports Exchange Server 2003 or later, which
implements VSS technology. However, if the database load is heavy, the VSS
request might be ignored. Create recovery points at the lightest load time.
Be sure that you have installed the latest service packs for your given database.
Note: For backing up Exchange databases, additional backup applications are not
needed to run with Symantec System Recovery.
