Abstract:
1. A computer-implemented method for removing unreferenced data segments from deduplicated data systems, the method comprising: identifying a deduplicated data system that contains a plurality of data segments, wherein the deduplicated data system reduces redundant data by only storing a single instance of each of the plurality of data segments; identifying a plurality of containers within the deduplicated data system, each container comprising a subset of the plurality of data segments within the deduplicated data system; identifying at least one container within the plurality of containers that includes a proportion of unreferenced data segments that exceeds a predetermined threshold, wherein the unreferenced data segments represent data segments that are not referenced by data objects within the deduplicated data system; for each identified container: wherein the computer-implemented method is performed by a computing device comprising at least one processor.
