1. A method in a computing system of creating snapshots for an information store, the method comprising: performing a first snapshot of data in an information store at a first storage device at a first time; selecting a first storage medium at a second storage device for storage of the data associated with the first snapshot, wherein the second storage device is separate from the first storage device; storing the data associated with the first snapshot in the first storage medium; tracking changes to the data associated with the first snapshot, the changes occuring between the first time and a second time occuring after the first time; performing at least a second snapshot of the data in the information store at the second time; selecting a second storage medium for storage of the tracked changes to the data associated with the first snapshot, wherein the second storage medium is different from the information store; storing, in the second storage medium, the tracked changes to the data associated with the first snapshot, wherein the storing of the tracked changes comprises copying the tracked changes to the second storage medium using information associated with the second snapshot to identify a location in the information store of the tracked changes to the data associated with the first snapshot; and tracking a location of the data associated with the first snapshot and the location in the information store of the tracked changes to the data associated with the first snapshot.
