Snapshot Group repository

The Snapshot Group repository is used to track data changes to the base volume (volume that the Snapshot Image was created from). The Snapshot Group repository may contain multiple Snapshot Images (point-in-time records of base volume). A Snapshot Volume is created from these images and can then be mapped to a host for access.
