Abstract
Techniques involve managing a storage system. Along these lines, for each of a plurality of snapshots, a plurality of blocks referenced by the snapshot is determined. An evaluation score indicating an impact that deletion of the snapshot has on space release and data retention is determined based on at least one of: a reference count for the plurality of blocks, a size of a storage resource associated with the snapshot, and the number of blocks of the plurality of blocks that are referenced only once. At least one snapshot to be deleted is selected from the plurality of snapshots based on respective evaluation scores of the plurality of snapshots.
