It's like someone glued together LVM and RAID but on file level instead of block level. So you can make some fancy things like (relatively) cost-free snapshots

So you can make some fancy things like (relatively) cost-free snapshots, and some extra data safety with per-file checksumming. It also uses WAL (similarly to databases) which allows (similiar to databases) replication to remote system.
- edmundsauto 3y agoGot it, that makes sense! Not OP but a followup - what does "replication" mean in this context? Is it mirroring your ZFS volumes in another device?
- ilyt 3y agoPretty much, although it's one-directional transfer of a volume or snapshot of one, not bi-directional one
