An Oracle database can be reverted to an earlier state from a Block based snapshot or clone. Crash consistent snapshots cannot be reverted.
Note: Revert overwrites the original database and destroys all data in that database as a result.
Note: When a single backup contains data of multiple databases, reverting to the backup will
corrupt all databases except the one which was selected for the backup and revert. Refer to
the list of Supported configurations and the Application software prerequisites to avoid this situation.
