- linsomniac 7y agoAs does ZFS, unless I'm missing some distinction of "first class" in ZFS. I'm really looking forward to Ubuntu 20.04 ZFS support. If I can use crypto with it (either the ZFS crypto or LUKS stuff), I'm going to switch my workstations over to it. ZFS snapshots work so, so well. One thing I've really wanted from HAMMER is the deduplication. I've always had problems with ZFS dedup. I tend to really want it on my backup servers, but the DDT requires pretty amazing amounts of RAM. HAMMER's dedup seems less RAM-hungry, but I've only run small tests of it.
