  • Publication number: 20050187992
    Abstract: The present invention relates to a method for tracking a plurality of snapshots of an information store. The present invention comprises performing a first snapshot of an information store that indexes the contents of the information store, copying the contents of the information store to a first storage device, using the first snapshot, and updating a replication volume table indicating the storage of the contents of the first information store using the first snapshot on the first storage device. A second snapshot is performed of the information store that indexes the contents of the information store, the contents of the information store are copied to a second storage device using the second snapshot and the replication volume table is updated to indicate the storage of the contents of the first information store using the second snapshot on the second storage device.

  • Publication number: 20050039069
    Abstract: The present invention provides computer systems, methods, and software products enabling the creation and maintenance of disaster recovery volumes having a reduced impact with regard to network traffic over a communications network. A disaster recovery volume is generally created at a local archival storage unit including therein at least one storage medium constituting the disaster recovery volume. The medium constituting the disaster recovery volume is associated with the primary volume thereby allowing the storage medium constituting the disaster recovery volume to be relocated to a remote archival storage unit at a remote location without compromising the association between the primary volume and the disaster recovery volume. Incremental changes to the primary volume may then be communicated and incorporated in to the disaster recovery relocated to the remote location.

  • Publication number: 20040250033
    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.
