The Oracle Recovery Manager (RMAN) is the preferred method for backup and recovery of databases contained in ASM. RMAN is very well integrated with ASM and is also used by third-party Oracle Database backup and recovery managers.
RMAN can back up from and recover to ASM. It can also use ASM as a store for backup sets.
Depending on the context, RMAN can reference individual ASM files or entire disk groups. For example, the following RMAN BACKUP command refers to an individual ASM file on the second line and also refers to an ASM disk group on the third line.
