Benefits of Recovery Appliance Storage

The benefits of Recovery Appliance storage locations are:

• More efficient disk usage

  Recovery Appliance uses common storage to absorb spikes from all protected databases, reducing the total amount of over-allocated storage. In traditional RMAN backup and recovery, a fast recovery area stores recovery-related files. Individual fast recovery areas require that each database maintain the amount of storage required to accommodate its largest expected activity spike, which often results in wasted storage.

  Note:

  The default storage location in the Recovery Appliance also contains a fast recovery area for catalog backups.

  Oracle recommends that protected databases continue to maintain fast recovery areas for storage of local online and archived redo log files, control file autobackups, and flashback logs. In a Recovery Appliance environment, the fast recovery areas have smaller space requirements because RMAN backups are stored in the Recovery Appliance.

• Database-optimized backup deduplication and compression

• Shared disk backup pool distributed based on database protection policy, which defines the disk recovery window goal for each database protected by the policy
