Abstract
A computer-implemented method for garbage collection in deduplicated data systems may include: 1) identifying a deduplicated data system, 2) identifying at least one segment object added to the deduplicated data system during a garbage-collection process of the deduplicated data system, 3) locking the segment object to prevent removal of the segment object by the garbage-collection process, and 4) unlocking the segment object after the garbage-collection process. The method may allow a small possibility of incorrectly removing useful segment objects. The method may also verify data objects during the garbage-collection process and recover incorrectly removed segment objects. Various other methods, systems, and computer-readable media are also disclosed.
