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’ve got a 3 node Proxmox/ceph cluster with 10G, plus a separate Nas. They are all rack mount with dual PSU. Add in the necessary switching, and my average load is about 800w. Throw my desktop (also on 10G) into the mix and it runs 1.1kw.

That’s roughly $50-60 extra in electricity costs for me monthly.

Average load for me is about 750W. I run my desktop from one of the UPS units in my rack, so when that’s on it sits around 1.1kW.

The 750W load is across 4 rack servers(1 is the NAS with 12 disks) and 3 switches.
