Example distributed reservation systems and methods are described. In one implementation, multiple storage nodes are configured to store distributed data. Multiple clients are coupled to the multiple storage nodes and access data from the multiple storage nodes. A management server is coupled to the multiple storage nodes and the multiple clients. The management server manages the access of data by the multiple clients and manages reservation of the multiple storage nodes by a particular client.

Distributed reservations systems and methods

Distributed reservation systems and methods

The present invention relates to a method for performing an image level copy of an information store. The present invention comprises performing a snapshot of an information store that indexes the contents of the information store, retrieving data associated with the contents of the information store from a file allocation table, copying the contents of the information store to a storage device based on the snapshot, and associating the retrieved data with the copied contents to provide file system information for the copied contents.

System and method for performing an image level snapshot and for restoring partial volume data

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.

Snapshot storage and management system with indexing and user interface

The invention provides a system and method for storing a copy of data stored in an information store. In one embodiment, a data agent reads one or more blocks containing the data from the information store. The data agent maps the one or more blocks to provide a mapping of the blocks, and transmits the one or more blocks and mapping to a media agent for a storage device. The media agent stores the one or more blocks in the storage device according to the mapping.

Systems and methods for transferring data in a block-level storage operation

The system and method are used for tracking a plurality of snapshots of an information store. The system performs 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.

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.
