Error during setup of component backup: 'state'

Installation
1

I was trying to figure out why a lamp that I had configured to switch on at sunset was switching itself off after about a half-hour without being told to do so. It turned out that the bulb must’ve been injecting noise that affected both the WiFi and Zigbee smart outlets I tried using it; replacing the bulb fixed it.

Along the way, I tried rolling back my Home Assistant installation (running the image from https://hub.docker.com/r/homeassistant/home-assistant). That didn’t work, and I started getting errors related to the database schema. I then put it back on the current version. The database errors went away, but now the backup integration refuses to run:

I could just wipe out the installation and rebuild as there aren’t that many devices up and running yet (just a Zigbee USB stick, smart outlet, and pushbutton are actively in use), but that would be kinda the “Windows way” to do things. :slight_smile: It looks like the backup integration is trying to do an upgrade on the database, but is failing. Is there something I could clear out in the database to get the backup integration working again?
