Abstract
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.
