Abstract
Change tracking for multiphase deduplication. In one example embodiment, a method of tracking changes to a source storage for multiphase deduplication includes a change tracking phase. The change tracking phase includes performing a hash function on each allocated block in a source storage that is changed between a prior point in time and a subsequent point in time, and tracking, in a change log, the location in the source storage of each changed block and the corresponding hash value. The hash function calculates a hash value corresponding to the changed block.
