lnbackup.

lnbackup is a backup program capable of creating backup directories that mirror the source without duplicating unmodified files.

Each run results in a new backup directory named with the date and time the backup started. Each backup directory is a complete mirror of the source. Unmodified backup files are hard linked. New backup files are created as copy-on-write duplicates of source files if possible. Files are also indexed by hash to identify moved, renamed, and duplicate files.
