Abstract:
Trimming unused blocks from a versioned image backup of a source storage that is stored in a sparse storage. In one example embodiment, a method may include identifying a versioned image backup of a source storage that is stored in a sparse storage. The method may further include deleting the first version of the versioned image backup from the sparse storage during a retention process, identifying a first set of blocks, identifying a second set of blocks, determining a third set of blocks that are included in the second set of blocks but are not included in the first set of blocks, and, after the retention process, trimming the third set of blocks from the second version of the versioned image backup that is stored in the sparse storage.
