My solution is to have a mini PC in a remote location which boots at a given time each day (BIOS option using RTC Clock). It autoconnects via Wireguard VPN to my home network. I have rest-server running in a container.

Locally, I have a cron job for restic backups to the remote rest-server, followed by an ssh command to update and power off.

Has been solid so far!

In Home Assistant, navigate to Settings > System > Backups. Configure the backup settings and create a manual backup.

On your new Proxmox server, you can download the qcow2 file from Home Assistant’s website and run it as a virtual machine.

On first boot, you can import your previous configuration from a backup.
