Abstract
A method, article of manufacture, and apparatus for recovering an index on a deduplicated storage device is discussed. A system index is merged into both a first persistent index and a second persistent index, wherein the system index comprises a plurality of buckets. A disrupting event is encountered during the merge. The first persistent index and the second persistent index are determined not to be synchronized as a result of the disrupting event. The merge is continued from a last synchronized location, wherein the last synchronized location comprises a bucket from the plurality of buckets that is successfully merged into both the first persistent index and the second persistent index.
