Abstract

A method and system backing up data files including a data storage device (470) for storing one or more data files (475). The method detects changed locations in one or more data files (475), stores the contents of the changed locations at a storage time and associates the stored contents with the storage time, the changed locations and one or more file identifiers identifying the one or more data files.
