Librsync

librsync is a free software library that implements the rsync remote-delta algorithm. This algorithm allows efficient remote updates of a file, without requiring the old and new versions to both be present at the sending end. The library uses a "streaming" design similar to that of zlib with... Platforms: *nix

pysync project is a Python implementation of rsync and related algorithms. Pysync has both a demonstration implementation of the rsync and related algorithms in pure Python, and a high speed librsync Python extension. The pure Python is not fast and is not optimized, however it does work and... Platforms: *nix

Duplicity backs directories by producing encrypted tar-format volumes and uploading them to a remote or local file server. Because duplicity uses librsync, the incremental archives are space efficient and only record the parts of files that have changed since the last backup. Because duplicity... Platforms: *nix

Burp is a backup and restore program. It uses librsync in order to save on the amount of space that is used by each backup. It also uses VSS (Volume Shadow Copy Service) to make snapshots when backing up Windows computers. It is open source free software (where 'free' means both that you do not... Platforms: Windows
