You can run a backup copy job to create secondary copies for application-aware backups and specify the copy precedence to restore application data from a secondary copy. By using this feature, you can restore data that has been copied to tape or other long term storage media.
Without this feature, you must restore application data from the primary Snap copy associated with the storage policy.
Backup copy operations for application-aware backups are supported for the following applications:
- Microsoft Exchange (for database restores only)
- Microsoft SQL Server
- Oracle database for Windows
Note: Granular recovery for Microsoft Exchange and Microsoft SharePoint is not supported for secondary copies, and must be performed from the primary Snap copy associated with the storage policy.
How Job Data Is Managed for Application-Aware Backup Copies
An application-aware backup is actually two jobs:
- The first job is the backup job submitted for a VSA subclient that was configured for application-aware backups. The VSA backup can be a streaming backup or an IntelliSnap backup.
- The second job is an IntelliSnap backup for the application data. This job is triggered automatically by the VSA backup.
Both the VSA job and the associated application job must be available when restoring data for an application. The point-in-time snapshot created by the application backup is part of the data that is stored for the VSA backup job.
Backup Copy Support
When backup copy operations are configured for application-aware backups, the backup copy job automatically moves application jobs with the associated VSA jobs, so that all of the information needed to perform restores is available from the secondary copy.
If either the VSA job or the application job is picked to be included with a backup copy operation, the associated job will also be moved to the secondary copy media.
The backup copy operation first moves VSA job data. If the VSA backup copy completes successfully, the backup copy continues by moving application job data.
Backup Copy Process
The backup copy operation performs the following actions:
- Launches the VSAApplicationBackupCopy process on the MediaAgent associated with the storage policy.
- The VSAApplicationBackupCopy process clones the snap entries and copies index entries for the application backup from the Snap copy to the secondary copy.
Configuration for Backup Copy Jobs
You must configure an automatic schedule for backup copy operations as part of a storage policy. For more information, see Configuring Offline Backup Copy for IntelliSnap Backup.
Note: For streaming VSA application-aware backups, application snap jobs are not automatically moved to secondary copies. You must run a backup copy job from the storage policy to move the application snap job data.
After configuring a backup copy operation for application-aware backups, you must run new backups before you can create secondary copies and restore from secondary copies.
Restores from Backup Copy Jobs
For application-aware backups, restores are always performed from the client for the application.
When initiating a browse and restore operation, you can select the copy precedence on the Copy Precedence tab in the Advanced Restore Options dialog box and enter the copy precedence number for the secondary copy.
You cannot perform a live browse on the secondary copy. Live browse is only available from the Snap copy for an application-aware backup.
