Abstract: Snapsets containing snapshots from a group of storage volumes are assigned snapset IDs. The same snapset ID is applied to each snapshot of the snapset, and is a globally unique value within the storage system. The snapset ID is assigned to a snapshot upon creation, and remains the same regardless of creation or deletion of other snapshots on the storage volume. By assigning a snapset ID to each snapshot of the snapset, and maintaining the snapset ID as a constant value as long as the snapshot is maintained on the storage system, it is possible to easily determine which snapshots form a given snapset. Control operations on particular storage groups or across storage groups are implemented by specifying particular actions to be taken on snapsets or snapshots, which are identified using the snapset IDs.
