Abstract
Embodiments for optimizing database backups to achieve a Recovery Time Object (RTO). A user-defined RTO configured for one or more databases is received. A backup frequency for initiating backups of the one or more databases is determined based on a continuously predicted recovery time associated with a plurality of factors. The backups of the one or more databases are executed at the determined backup frequency to ensure the user-defined RTO is achieved for the backups of the one or more databases. In some embodiments, a recovery window of the one or more databases may be increased using an RTO-aware tiered or remote storage caching operation for portions of the database, and an RTO-aware re-sharding operation on sharded databases may be performed when the backup frequency exceeds a predetermined threshold such that each shard may be restored within the user-defined RTO.
