description A method and apparatus for optimizing a de-duplication rate for backup streams is described. In one embodiment, the method for optimizing data de-duplication using an extent mapping of a backup stream includes processing a backup stream to access an extent mapping associated with a plurality of data files, wherein the plurality of the data files are arranged within the backup stream and examining the extent mapping to identify at least one extent group within the backup stream, wherein the plurality of the data files are de-duplicated using at least one location of the at least one extent group.
