When a Data Guard strategy of backing up from both the Primary and Standby Database Server is implemented with backups from the Primary and Standby Database Servers being interchangeable, you might want to be able to select the source of the backup during a restore. For example, you might want to restore from the Primary Database Server versus the Standby Database Server. The User Defined Backup Tag option lets you assign a tag to the backups that indicates the source of the backup — the Primary Database Server or the Standby Database Server. During the restore, the User Defined Backup Tag is specified in the Restore Options to ensure that only backups from the applicable server are used for the restore.

When performing restores in a Data Guard environment where the backup is being restored to the same Database Server where the backup was taken, there is no difference between performing the restore in a Data Guard environment or a non-Data Guard environment. For more information on single-instance environments, see Performing RMAN restores. For more information on multi-instance environments, see Restoring data in a RAC environment.
When performing restores in a Data Guard environment where the backup is restored to an alternate Database Server in the Data Guard environment, the restore is identical to restoring to the same Database Server except for the differences detailed in the following topics.
