Home Assistant Core LXC - restore?

[tomasenskede]

I am running Home Assistant in a Proxmox VM, and it works fine, except for occasional CPU spikes. I am exploring the possibility of moving to an LXC container, as I have had good experiences using LXC instead of a VM for several reasons.

Now, after running this excellent script, I have a functional Home Assistant LXC container :) but... the restore doesn't work. I transfer a full backup, and it shows up, but I can't restore it... why?

Home Assistant Core supports making backups via the GUI, but restores need to be done manually.

What backup are you restoring?
The small one is probably not correct.

Is there an error?

Also, to not get the CPU spikes in the VM, I found out that rebooting after an update works.
As I prefer the VM, as it has better hardware pass-through and the reboots works for me.
