Abstract
An apparatus includes a processing device configured to identify a snapshot policy for creating a snapshot lineage comprising snapshots of a storage volume comprising data stored on a storage system, the snapshot lineage comprising (i) a local snapshot lineage stored on the storage system and (ii) at least one cloud snapshot lineage stored on cloud storage. The processing device is also configured to generate snapshots of the storage volume in accordance with the snapshot policy, to store the snapshots in the local snapshot lineage, and to copy snapshots from the local snapshot lineage to the at least one cloud snapshot lineage in accordance with the at least one snapshot policy. The processing device is further configured to provide an interface for managing the snapshot lineage by accessing, from the storage system, snapshots of the storage volume in the local snapshot lineage and the at least one cloud snapshot lineage.
