摘要
An apparatus comprises a processing device configured to identify a 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, in accordance with a snapshot policy, a snapshot in the local snapshot lineage to copy to the cloud snapshot lineage. The processing device is further configured to create a virtual device on the storage system, to link the selected snapshot to the virtual device, to determine data of the selected snapshot that is to be copied from the virtual device to a cloud storage volume on the cloud storage, and to copy the selected snapshot to the cloud snapshot lineage by copying the determined data from the virtual device to the cloud storage volume.
