It's kludgey to graft snapshots and compression onto a classic in-place filesystem, so you'd probably end up with something slower and more complex than ZFS/btrfs/bcachefs. I remember tux2/tux3 was touting its simplicity but I don't know what happened.
- 5e92cb50239222b 3y agoDave Chinner somehow managed to put reflinks on top of XFS, although it's not nearly the same as full filesystem snapshots. I believe there was discussion about implementing proper snapshots, but XFS is very conservatively developed, so that may be many years in the future, if it ever happens.
