rdiff-backup

Resources

rdiff-backup is a GPL-licensed incremental backup utility based on librsync; it stores changes to files instead of entire duplications. This can greatly reduce storage requirements for backups. The resultant incremental data can be viewed and restored from as if it were whole file backups via FUSE-based rdiff-backup-fs.
