From Just Solve the File Format Problem

SDFS is a filesystem from OpenDedup which supports both cloud and local storage. It uses deduplication to save space in storing data that contains many redundant blocks, which is of greatest utility for backup and archival systems where there are numerous versions of the same file stored with only slight changes. (Note that this is the inverse of what is done in RAID systems, where redundancy is created for the purpose of file reliability in the face of data loss; deduplication systems instead prioritize efficiency of storage by removing redundancy.) SDFS is available for several operating systems including Windows and several flavors of Linux.
