Abstract
A snapshot usage tracking system and method for a versioned storage is provided. The system includes a memory having computer-readable instructions stored therein and a snapshot repository configured to store a plurality of snapshots of a versioned storage. Each of the plurality of snapshots includes one or more data blocks. The system further includes a processor communicatively coupled to the snapshot repository and configured to maintain a set of snapshot counters corresponding to each of previous snapshots created on or before a current snapshot based upon a size of the data blocks that are modified or deleted in the current snapshot.
