Thanks for the input, sorry for the delayed answer.

I was looking into the replication feature, and it sounds cool. I can acquire used identical devices from work, which is handy for this.

These are my ideas now, feedback would be greatly appreciated:

A) Get another identical device, upgrade the internal storage to 1tb nvme and setup Proxmox. Move existing ct’s /vm’s to that while upgrading the storage on the other device to same kind of storage and reinstalling Proxmox, then joining them as nodes in a cluster with replication. Correct thinking?

B) Get another identical device, upgrade the internal storage to 1tb nvme and setup Proxmox Backup Server. Backup the ct’s / vm’s, upgrade storage on the the other device to same kind of storage and reinstalling Proxmox, then restoring the vm’s / ct’s and have it act as the main server.

In either case, there would be two identical devices, providing different types of backup.

I’d also add a third device, a simpler NAS with more storage for Plex and other stuff. This might or might not be backed up, as it’s not that important. I might even experiment with something like GlusterFS, since the main cost for me is the HDD/SDD storage space. Electricity is cheap for me and SFF don’t take up much space.

Any thoughts?

Thanks for the reply. Yes, sounds good.

Hi, thanks for the reply. Yeah, that is of course an possibility also, just backup the containers and vms and start over. But I’m still keen on the idea of adding another device, possibly for mirroring or other types of backup.
