ABSTRACT:
A storage system, such as a file server, creates persistent consistency point images (PCPI) or “snapshots” that are point-in-time representations of the storage system. The storage system uses persistent consistency point images to backup or mirror data. Using data already found in the data block maps associated with these PCPI, the amount of space used by a set of these consistency points can be determined.
