Recovery Manager (RMAN) is an Oracle utility that is used to manage backup and recovery operations. Recovery Manager can back up database files (data files, control files, and archived redo log files) and restore or recover a database by using a backup.
Recovery Manager uses a central information repository called recovery catalog in order to store metadata about backup and recovery operations. However, if a recovery catalog is not created, Recovery Manager uses the target database's (the database that RMAN is backing up or restoring) control file as a repository for storing the information necessary for backup and recovery operations.
Recovery Manager can be invoked as a command line utility from the operating system command prompt. However, its few features can also be used through Oracle Enterprise Manager GUI.
