This repository contains:

  • duperemove (v0.10)
  • xxhsum, libxxhash, libxxhash-devel (xxHash 0.6.2)


Duperemove is a simple tool for finding duplicated extents and submitting them for deduplication. When given a list of files it will hash their contents on a block by block basis and compare those hashes to each other, finding and categorizing extents that match each other. When given the -d option, duperemove will submit those extents for deduplication using the btrfs-extent-same ioctl.

!!! bedup is unmaintained, and does not use the safe deduplication ioctl. Use duperemove instead. !!!

xxHash is an Extremely fast Hash algorithm, running at RAM speed limits. It successfully completes the SMHasher test suite which evaluates collision, dispersion and randomness qualities of hash functions.

xxhsum code is used by duperemove, but the library is not shared yet
