Patent number: 8433872Abstract: 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. Multiple 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.Type: GrantFiled: March 20, 2012Date of Patent: April 30, 2013Assignee: CommVault Systems, Inc.Inventors: Anand Prahlad, Andreas May, Norman R. Lunde, Lixin Zhou, Avinash Kumar, David Ngo

Publication number: 20130013563Abstract: The present invention relates to a method for performing integrated storage operations on an information store. The present invention comprises identifying a plurality disparate types of storage operations stored in a policy option table. A first storage operation is performed according to a first set of storage criteria stored in the policy option table and a second operation, disparate from the first storage operation, is performed according to a second set of storage criteria stored in the policy option table.Type: ApplicationFiled: September 14, 2012Publication date: January 10, 2013Applicant: CommVault Systems, Inc.Inventors: Anand Prahlad, David Ngo, Lixin Zhou, Andreas May

Publication number: 20100114837Abstract: 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.Type: ApplicationFiled: January 13, 2010Publication date: May 6, 2010Inventors: Anand Prahlad, David Ngo, Norman R.
