Oracle Database provides RMAN for backing up and restoring the database. RMAN enables you to back up, restore, and recover data files, control files, SPFILEs, and archived redo logs. RMAN is included with the Oracle Database server and it is installed by default. You can run RMAN from the command line or you can use it from the Backup Manager in Oracle Enterprise Manager. In addition, RMAN is the recommended backup and recovery tool if you are using Oracle Automatic Storage Management (Oracle ASM). The procedures for using RMAN in Oracle RAC environments do not differ substantially from those for Oracle noncluster environments.
