I created a backup of my HA install from the VM. I then installed HA on RPi4 and tried to restore the backup, but it ends up with an error
Unknown error, see supervisor
If I go to System/Logs it says “There are no new issues”. Downloading Full Logs produces an empty file.
I can’t even ssh into the install, because after installing the SSH addon, it will not start. And the logs remain empty.
Try to open the backup to see if there is a homeassistant folder included.
Sometimes the backup does not finish correctly, so trying to install a backup file from such an event will always fail.
You can often use a zip program to open the files.
I use 7-zip, but WinZip or WinRAR should work too.
Yeah, it looks complete.
Maybe a manual restore of the folders could solve it.
It should be possible, but I have no experience in it, so hopefully someone else can help here.
Is there really no working backup/restore function in Home Assistant?
Seems you are using google drive to backup your installation. Check out this guide. It contains lots of useful information incl. backups to google drive. https://www.derekseaman.com/2023/04/home-assistant-pt-3-restoring-your-configuration.html
The backups were from v10, while the new HAOS was v11. I upgraded the source to v11, made a new backup and then the restore worked.
