Database-Aware Space Management

Using protection policies, the Recovery Appliance manages backup storage space according to the recovery window goal for each protected database. This granular, database-oriented space management approach eliminates the need to manage space at the storage-volume level, as third-party appliances do.

If space is available, then the Recovery Appliance may retain backups older than the recovery window goal, effectively extending the point-in-time recovery period. When space pressure exists, the Recovery Appliance uses predefined thresholds to purge backups. The Recovery Appliance automatically provisions space so that the recovery window goal for each database is met.

The Oracle Zero Data Loss Recovery Appliance with Release 21.1 supports immutable backups, which are a requirement of various government regulations such as SEC 17(a)-4f and others from FINRA, CFTC, MiFID II, which specify rules for compliance retention and legal holds.

The "Recovery Window Compliance" is a range of time that the Recovery Appliance will ensure databases can be recovered from their backups. When defined in the protection policy, newly created backups of that policy are held on the Recovery Appliance for that period of time. Recovery window compliance is different and more restrictive than the recover window goal.

If compliance features are not enabled, the protection policy can make use of "autotune reserved space", which has the Recovery Appliance automatically define and update the storage space.
