For Oracle fault tolerance, back up your Oracle database. To do this, we recommend using Oracle’s Recovery Manager (RMAN) backup utility. This is an Oracle tool that lets you back up, copy, restore, and recover data files, control files, and archived redo logs. It is included with Oracle server and does not require a separate installation.
For details about using RMAN, see the Recovery Manager User's Guide provided by Oracle.
Note that this application only stores business data in Oracle, so any metadata (logging, class, scheduling, and so on) backup still requires an embedded database backup.
