During an offline backup, the database is shutdown and is not available for use. The full backup includes all the datafiles, tablespaces, and control file of the Oracle database. Note that, offline backups do not include the archived log files.
Offline backups can be performed when the database is in offline or online mode. If the database is online, it shuts down the database, performs the backup and then brings up the database back.
In order to backup the Oracle database when it is offline, you need to create a separate user-defined subclient for offline backup. Make sure that the database is in the MOUNT mode during the backup.
Before You Begin
Optional: You can have data and log backups use different compression. If you want to use the MediaAgent for compression for log backups, see Enabling MediaAgent Compression for Oracle or Oracle RAC Log Backups.
