Abstract
An apparatus comprises a processing device configured to identify a snapshot lineage comprising snapshots of a given set of storage volumes, the snapshot lineage comprising (i) a local snapshot lineage stored on a storage system and (ii) a cloud snapshot lineage stored on cloud storage of a cloud external to the storage system. The processing device is also configured to select a snapshot to recover from the cloud snapshot lineage to the storage system, to create a set of new storage volumes on the storage system, to generate a recovery map linking each of a set of cloud storage volumes on the cloud storage that comprises data of the selected snapshot to at least one of the new storage volumes, and to recover the selected snapshot from the cloud snapshot lineage by copying data from the set of cloud storage volumes to corresponding linked ones of the new storage volumes.
