Abstract
A computer-implemented method for reclaiming storage space in deduplicating data systems may include (1) storing at least one non-synthesized backup image within a deduplicating data system by storing at least one data segment of the non-synthesized backup image within a container of deduplicated data segments that is used by the deduplicating data system, (2) storing at least one synthesized backup image within the deduplicating data system by referencing at least one previously stored data segment within the container that is also referenced by a previous backup image within the deduplicating data system, (3) determining that no non-synthesized backup images still reference the container, and (4) removing the data segment of the non-synthesized backup image from the container of deduplicated data segments in response to determining that no non-synthesized backup images still reference the container. Various other methods, systems, and computer-readable media are also disclosed.
