Description Ivan Zakharyaschev 2013-02-06 00:31:40 MSK
https://btrfs.wiki.kernel.org/index.php/Deduplication :

bedup implements incremental offline whole-file deduplication for Btrfs.

It works on mainline kernels (Linux 3.3 is required by the file locking implementation, 3.6 is required for cross-subvolume operation), using the clone ioctl (which exposes Btrfs' copy-on-write functionality).

Comment 1 Ivan Zakharyaschev 2013-02-06 00:35:31 MSK
Probably, the package with it could include a script for cron to run deduplication regulalrly, say, every day (or week) at night -- which could be turned on by those who wish.
