I’m in the process of migrating my HASS installation from a VirtualBox VM running on Windows to a Proxmox VM using Home Assistant OS.
Every step of the way, the built-in backup/restore features are causing frustration. I backed up my previous instance and downloaded the .tar file to my laptop. Then:
- I tried to restore from the HASS setup screen (before even creating a user). When it asked me to upload my backup file, it failed immediately (400 bad request). There are bugs about this on GitHub that are more than 2 years old by the way, with no definitive resolution.
- The threads I found said to just go ahead and setup a user, and then restore from the Settings → System → Backups screen. Tried that; 400 Bad Request when uploading the file.
- Installed the Samba add-on, connected to the /backup share, and uploaded my .tar file. It’s not showing in the backups list on the new installation, it says “You don’t have any backups yet”. Clicking the menu->Reload on the backups list does nothing. Restarting does nothing. The tar file is definitely in the backup folder.
What am I supposed to do now? I’ve read articles and watched videos where this just works for people, with much larger files than mine (around 152 MB), why isn’t this working?
I don’t know if it’s relevant, but one odd thing is that the backup entry in my old installation is listed as 237 MB, but the downloaded file is only 152 MB. I’m not sure if that’s expected because it’s compressing it on the way out, or if it’s a sign of a problem.
