ZFS Thoughts on using ZFS native encryption for backups on external storage

[rbranco]

I've been using LUKS over ext4/xfs for my backups that I can't use with FreeBSD for obvious reasons.

I've been experimenting with ZFS and I'm really impressed with its speed when switching branches with git, even with noatime set on UFS2.

I'm planning to migrate to ZFS on all my systems for greater interoperability. I also plan to migrate my backups on external storage.

Is ZFS native encryption ok for that? Which ZFS specific options & configuration I should be aware of?

My thought on this issue is that ZFS encryption had a lot less review by cryptography experts than Linux'.
