International Classification:

G06F 13/00

US Classification:

711162, 707204

Abstract:

A system and method of managing stored data in a storage management system. The storage management system includes a storage manager, a media agent connected to the storage manager, and a primary volume connected to the media agent. A plurality of snapshots are taken of the primary volume. The snapshots are indexed by associating respective information with the snapshot. The indexed snapshots are copied to a recovery volume. In this way, browsing features are enabled for the user. The user may view the snapshots in a hierarchical format, and may even view snapshot data in association with the corresponding application. The resultant recovery volume may be used to replace a primary volume.
