Advantage of RMAN:
- Incremental where only modified data blocks will be
copied
- Integrity check for the data block in case they are
corrupted
- Can do parallelism instead of sequential
- It automatically manages the backup files without
DBA intervention.
- It automatically deletes unnecessary backup
datafiles and archived redo log files both from disk and tape.
- Only RMAN provides the ability to perform encrypted
backups.
- RMAN manages the delete
archivelog policy.
