The reasoning is that your backup server should be more secure than production. Production has to have a bunch of stuff open in order to be useful and convenient. The backup server does not. It can be basically fully locked down.

Sorry I can’t help with the proxmox stuff but it is absolutely fine to have a qcow2 image on an SSD pool. Modern SSD write endurance is so high as to be a non issue especially in the relatively tiny work loads that HA will put on it

This is huge for me as well and is what will keep me on Ubuntu Server until I have a very very good reason to leave or someone else adds it.
