ABSTRACT:
In a method for repairing a corrupt data segment used by a de-duplication engine, a data segment indexed by a de-duplication index is identified as being as a corrupt data segment. A search is made to find a duplicate data segment with which to replace the corrupt data segment, where the duplicate data segment comprises an uncorrupted version of the data segment. The corrupt data segment is replaced with the duplicate data segment.
