Abstract
Systems, methods, and software are disclosed herein for identifying duplicate blocks of a storage system and deduplicating the storage system. In one example, a method of operating a computing device includes scanning first metadata of blocks of a container file of a virtual volume to generate a first log file including records of virtual volume block numbers (VVBNs) and fingerprints of the blocks; scanning second metadata of blocks of an active file system of the virtual volume to generate a second log file including records of VVBNs and file block numbers (FBNs) of the blocks; generating tuples based on merging the records of the first log file and the second records of the second log file according to the VVBNs; identifying duplications among the blocks based on the tuples; and deduplicating the blocks based on the duplications in the active file system identified based on the tuples.
