Abstract
A computer-implemented method for removing unreferenced data segments from deduplicated data systems may include: 1) identifying a deduplicated data system that contains a plurality of data segments, 2) identifying a plurality of containers within the deduplicated data system, with each container containing a subset of the data segments within the deduplicated data system, 3) identifying at least one container within the plurality of containers that is likely to include a large proportion of data segments that are not referenced by data objects within the deduplicated data system, and then, for each identified container, 4) searching for unreferenced data segments within the identified container and 5) removing the unreferenced data segments from the identified container. Various other methods, systems, and computer-readable media are also disclosed.
