This is very similar to how I run mine, except that I use Ceph instead of ZFS. Nightly backups of the CephFS data with Duplicati, followed by staggered nightly backups for all VMs and containers to a PBS VM on a the NAS. File backups from unraid get sent up to CrashPlan.
Slightly fewer retention points to cut down on overall storage, and a similar test pattern.
Yes, current sysadmin.
I would like to play with ceph but I don't have a lot of spare equipment anymore, and I understand ZFS pretty well, and trust it. Maybe the next cluster upgrade if I ever do another one.
And I have an almost unhealthy paranoia after see so many shitshows in my career, so having a pile of copies just helps me sleep at night. The day I have to delve into the last layer is the day I build another layer, but that hasn't happened recently. PBS dedup is pretty damn good so it's not much extra to keep a lot of copies.
