I wonder why ZFS is marked as not having de-dupe (deduplication).
AFAIK ZFS has had deduplication support for a very long time (2009) and now even does opportunistic block cloning with much less overhead.
- adrian_b 2y agoAlso XFS has deduplication now, already for some time, at least one year or two.
- BlackLotus89 2y agobtrfs has deduplication as well. In theory full file deduplication exists in every filesystem that has cow/reflink support
- Tobu 2y agofclones for example covers it well for any filesystem with reflinks: https://lib.rs/crates/fclones https://lib.rs/crates/fclones fclones group |fclones dedupe
- ksec 2y agoYes I sort of skip-read a lot of it after that.
- the8472 2y agoZFS online deduplication is not comparable with on-demand dedup offered btrfs and xfs and is prohibitively expensive for many workloads. The new block cloning still had data corruption bugs quite recently.
- BSDobelix 2y ago>ZFS online deduplication is not comparable with on-demand dedup offered btrfs and xfs But it has de-duplication, with your logic no non-CoW FS should be in that list because they are not comparable.
- prmoustache 2y agoIt is still deduplication. Chart should have a bloc dedup and file dedup separated columns if it is deemed non comparable.
