Abstract
An apparatus comprises a processing device configured to receive a request to perform merging in a snapshot mapping structure comprising objects representing a given storage volume and its snapshots. The objects are organized in a tree structure representing data dependencies between the given storage volume and its snapshots. The processing device is also configured to analyze the snapshot mapping structure to identify ones of the objects that are candidates for deletion and to determine merge groups. A given one of the merge groups includes (i) at least a subset of the objects identified as candidates for deletion and (ii) a given object that is a child object of at least one of the subset of the objects identified as candidates for deletion. The processing device is further configured to perform merging in the snapshot mapping structure by merging data items in the given merge group to one of its objects.
