Abstract
Described is a system for managing point-in-time backups (or 'snapshots') of data that are stored as part of a primary storage. As part of a data protection service, a set of snapshots may be stored on the primary storage system for efficient and immediate recovery, and a set of corresponding recovery snapshots may be stored on a secondary storage system for recovery purposes. Accordingly, the system may provide the ability to leverage the efficient storage mechanisms of the primary storage, while still maintaining the data storage efficiency (e.g. costs) of the secondary storage. Moreover, the system may manage the snapshots stored on the primary and secondary storages independently. For example, the system may fully leverage the available capacity of storage pools within the primary storage by automatically purging certain snapshots from the primary storage while still maintaining the corresponding recovery snapshots on the secondary storage.
