SnapManager performs backup individually for each volume you choose to back up, using the following sequence. For example, if two separate volumes are involved, SnapManager performs the sequence of steps once for the first volume, then again for the second volume.
To create a backup, SnapManager performs the following sequence of steps:
- Checks the SnapManager license
- Renames the most recent SnapInfo directory, if required
- Renames the most recent Snapshot copy, if you choose the generic naming convention
- Creates a SnapInfo directory for the backup
- Initiates a VSS backup
When you back up data from an LCR or a CCR location, SnapManager uses VSS replication writer to back up the database.
- Gathers Exchange metadata and activates the VSS Snapshot copy set
- Adds all required volumes to the VSS Snapshot copy set
- Creates a volume shadow copy
The transaction logs are backed up and truncated during this step.
- Verifies the physical integrity of the database
- Creates a SnapInfo Snapshot copy
- Deletes the SnapInfo Snapshot copies for the deleted backups
- Deletes any specified older backups
