RMAN can automatically locate, back up, restore, and recover datafiles,
control files, and archived redo logs. Since Oracle9i, RMAN can restart backups and
restore and implement recovery window policies when backups expire. Oracle Enterprise
Manager provides a GUI-based interface to RMAN. Oracle Enterprise Manager
10g introduced an improved job scheduler that can be used with RMAN for managing
automatic backups to disk.
Incremental backup and recovery
RMAN can perform incremental backups of Enterprise Edition databases. Incremental
backups will back up only the blocks modified since the last backup of a datafile,
tablespace, or database; thus, they??™re smaller and faster than complete backups.
RMAN can also perform point-in-time recovery, which allows the recovery of data
until just prior to an undesirable event (such as the mistaken dropping of a table).

Oracle Secure Backup
Various media-management software vendors leverage Oracle??™s RMAN, but starting
with Oracle Database 10g, the database also includes an entry-level tape storage
management solution of its own known as Oracle Secure Backup XE.
