The method includes creating a snapshot object for interfacing with functionalities of the system; and using the snapshot object, creating a first collection of System State objects which record the status of the system at a given instant in time. Next, the first collection of System State objects is stored in the memory. A second collection of System State objects, which was previously created and stored in the storage device, is then loaded into the memory.
