Abstract: In a method for deleting a cascaded snapshot, a storage device includes a logical volume corresponding to a plurality of cascaded snapshots. The plurality of cascaded snapshots comprises at least a first snapshot, a second snapshot, and a third snapshot. The second snapshot is a parent snapshot of the first snapshot, the third snapshot being a child snapshot of the first snapshot. The storage device receives an instruction for deleting the first snapshot. The first snapshot comprises target data. The storage device migrates information of the target data to the second snapshot. Further, the storage device sets a parent snapshot identifier corresponding to the third snapshot to an identifier of the second snapshot, and deletes the first snapshot.
