Configuring an Oracle RAC Offline Subclient

During an offline backup, the database is shutdown and is not available for use. Since incremental backups require access to various tablespaces and datafiles, it is always recommended that you perform a full backup of the database when it is offline. 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

If you want to use the Oracle RMAN backup copy option by using a proxy server, you must contact Oracle for their required licensing.
