Abstract
A method to create a version map to represent the data state of a file at a particular point in time when an incremental backup is performed. In one embodiment, a logical memory backup file is created that is known as a cumulative data file. Changes to the cumulative data file according to one embodiment of the present invention include appending copies of modified data when the modified data meets a certain condition. A new version map may be created each time an incremental backup occurs. Locations of both modified and unmodified data in the backup data file are mapped for future reference to the data.
