I discovered late last night that my Home Assistant docker has disappeared. Reinstalling has no effect.

I've been working on system back ups also and recently installed Appdata Backup and Duplicati...pretty sure I have the former buggered up to as I keep getting an error notifcation, but can't deduce the related Nextcloud AIO issue. My plan was to back up full system data with Duplicati, and use Appdata Backup to back up app data. My son also runs an Unraid server, so our next steps are to use each other's servers to facilitate off-site back up copies.

Reinstalling Home Assistant has no effect and I suspect I've blown out the appdata files by running clean up scripts to clear out any dangling junk.

It's all a mess and I thought it was going so well...

I went through your diagnostics and your screenshot. "docker ps -a" shows 13 containers and no Home Assistant, not even a stopped one, so the container itself was removed. The two paths you tried (/opt/homeassistant, /usr/share/hassio) don't exist on Unraid; with your Docker settings the data would be in a folder under /mnt/user/appdata/. The diagnostics don't list that folder, so they can't show whether the data is still there. A few things they do show:

- Appdata Backup has run every night at 00:00 and was killed before it finished on Nov 12, 13 and 14 ("exit status 137", each time a few seconds after the last container was started again). That is probably the error you keep getting. The syslog doesn't show what killed it; the plugin's own log should: Settings → Backup/Restore Appdata → Status / Log.

- Home Assistant was not among the containers Unraid auto-started on Nov 11 either. So unless it had autostart off, it may already have been gone three days ago.

- Your notification mails fail every night: Gmail rejects the login, it wants an app password.

The possible good news: each nightly run writes a folder ab_<date>_<time> to your backup destination, with one archive per container and a copy of the container templates. If Home Assistant was selected, its appdata may still be in one of the older folders and can be put back from the plugin's Restore tab.

Before changing anything else, could you post:

1. What exactly happens when you reinstall it (from Apps → Previous Apps?): is there an error, or does it install and come up empty?

2. The output of this command:

ls -la /mnt/user/appdata/

3. A listing of your Appdata Backup destination folder.

4. The content of the clean-up scripts you ran. The log shows delete_dangling_images, Check Docker Image, delete.ds_store and viewDockerLogSize on Nov 12 and 14.

Please don't run any more clean-up scripts until we know where the data is.
