One more option there I forgot to mention... There are various dedup tools out there. See the wiki ( https://btrfs.wiki.kernel.org ) and the list archive for more as I've not used any of them myself, but in theory at least, the dedup tools should help you recover the space, and I / think/ they'll do so without forcing either snapshot deletion or a fresh mkfs.btrfs and restore from backup, too, those being the other options I mentioned. -- Duncan - List replies preferred.
