mentioned:

Please let me know if anyone who does not have access to the wiki has
any additions, updates or corrections to what I've written here.

Hi all,
I'm pleased to announce my btrfs deduplication utility, written in
Rust. This operates on whole files, is fast, and I believe
complements the existing utilities (duperemove, bedup), which exist
currently.
Please visit the homepage for more information:

Thanks for having shared your work.
Please be aware of these other similar softwares:
- jdupes: https://github.com/jbruchon/jdupes
- rmlint: https://github.com/sahib/rmlint
And of course fdupes.
Some intesting points I have seen in them:
- use xxhash to identify potential duplicates (huge speedup)
- ability to deduplicate read-only snapshots
- identify potential reflinked files (see also my email here:
https://www.spinics.net/lists/linux-btrfs/msg60081.html)
- ability to filter out hardlinks
- triangle problem: see jdupes readme
- jdupes has started the process to be included in Debian
I hope that will help and that you can share some codes with them !
