Supervisor does not recognize backup file. Backups Fail

Supervisor does not recognize backup file. This is exactly the issue reported in issue: #3707. This occurred for me after the installation of Core: 2024.8.3 and Supervisor: 2024.08.0.

Simply attempting a full backup produces the errors identified in the Supervisor and Core log files provided below.

It will backup Add-Ons Only and Folders Only as a Partial Backup but the errors occur when trying to backup Home Assistant (2024.8.3) even as a Partial backup of Only HA…

Note: ./backup.json file is not in the backup directory. Only the last 3 successful backups are present in the directory. Additionally, The backup process does create a 10KB file each time a backup is attempted. Therefore it is attempting to start the backup process. I have MANY MANY hours in Home Assistant and I am on pins and needles right now without a backup solution. Any assistant that anyone can offer would be very much appreciated.

Until you get this solved you can just copy your entire /config folder including any hidden sub-folders to a location off your HA system.

This will back up everything except add-ons.

Tom,

Thank you for the confirmation. This is much appreciated. The HA backup will still backup the Add-ons and Folders. With your confirmation of the Config, and the aforementioned partial backup of the Folders and Add-ons, I can manually tar the Config and anticipate that I have a temporary backup solution until this issue is resolved.
