Error creating backup - blocked from execution

[bradmatt275]

Describe the issue you are experiencing

Automated backup fails almost every night with the following error:

[140192399060864] Error handling message: Error creating backup: 'BackupManager.do_backup_partial' blocked from execution, system is not running - freeze (home_assistant_error) from 192.168.4.12 (Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/132.0.0.0 Safari/537.36)

Restarting or repairing supervisor fixes it temporarily but the issue re-appears the next day.

What type of installation are you running?

Home Assistant OS

Which operating system are you running on?

Home Assistant Operating System

Steps to reproduce the issue

1. Go to Settings > Systems > Backups.
2. Run either a manual or automated backup.
   For the sake of ruling out add-ons as an issue I un-ticked everything except for HA settings and changed add-ons to None
3. Set the location to this system.
4. Press create backup.
5. Backup will fail immediately.

Anything in the Supervisor logs that might be useful for us?

Additional information

I don't think the issue is related to any particular release. It's been happening for about a year.

I didn't log anything previously because I was just using manual backups. It was easy enough to just restart supervisor when needed. However, I would really like to start using automated backups.

I have tried repairing supervisor and even rebuilding the VM running HAOS and restoring my config.

I haven't tried building a new instance of HA without restoring any config. I would really like to avoid that if I can.
