Bud

Bud is a simple utility used to incrementally back-up directory. This is achieved by hard linking backed-up files with the same CRC-32 hash.

Currently its only available as a Bourne shell script, but I may also write a C version once I'm satisfied with its core functionality. It only requires tools found in Busybox or GNU Coreutils.
