Recovery Manager
Recovery Manager (RMAN) provides a comprehensive foundation for efficiently backing up and recovering the database. RMAN eliminates operational complexity while providing superior performance and availability of the database.
RMAN determines the most efficient method of running the requested backup, restoration, or recovery operation and then submits these operations to the Oracle AI Database server for processing. RMAN and the server automatically identify modifications to the structure of the database and dynamically adjust the required operation to adapt to the changes.
RMAN is the standard interface to backup and restore from Recovery Appliance, local disk (ZFS storage), tape, and cloud object store.
RMAN provides the following benefits:
-
Support for Oracle Sharding - RMAN support for every independent database (shard)
-
Enhancement for Sparse Databases - allows backup and restore to operate on
SPARSEbackup sets and or image copies
-

command - Support for Oracle Multitenant, including backup and recovery of individual pluggable databases
- Support for cross-platform Oracle Multitenant, including backup and recovery of individual PDBs
- Automatic channel failover on backup and restore operations
- Automatic failover to a previous backup when the restore operation discovers a missing or corrupt backup
- Automatic creation of new database files and temporary files during recovery
- Automatic recovery through a previous point-in-time recoveryâ€"recovery through reset logs
- Block media recovery, which enables the data file to remain online while fixing the block corruption
- Fast incremental backups using block change tracking
- Fast backup and restore operations with intrafile and interfile parallelism
- Enhanced security with a virtual private recovery catalog
- Merger of incremental backups into image copies, providing up-to-date recoverability
- Optimized backup and restoration of required files only
- Retention policy to ensure that relevant backups are retained
- Ability to resume backup and restore operations in case of failure
- Automatic backup of the control file and the server parameter file, ensuring that backup metadata is available in times of database structural changes and media failure and disasters
