Abstract
Snapshot management means intervenes between a file system for managing access, including update, to files stored in nonvolatile storage devices and the nonvolatile storage devices. The snapshot management means creates a snapshot holding the contents of the files at a specific point in time for each of the nonvolatile storage devices and stores the created snapshot into the corresponding nonvolatile storage device. The configuration makes it possible to create snapshots effectively without any modification to application programs or a file system.
