automatic backup feature

[Anto79-ops]

The problem

hello!

I setup the automatic backup feature on 2025.1.0b0 (thanks for adding this!), and selected my settings and saved. It created a backup immediately, however, when checking the backup page, it shows that I have no automatic backups, but there is 1 listed. Does this mean it just didn't run for the first time on its own or perhaps a bug:

FYI, I originaly setup the backup locations to all possible locations, 3 local and 1 Nabu Casa cloud. However, the backup is 13.1 GB and it failed to upload to Nabu Casa, so I checked off Nabu Casa:

just in case those logs are here:

    )

The above exception was the direct cause of the following exception:

  File "/usr/src/homeassistant/homeassistant/components/cloud/backup.py", line 173, in async_upload_backup
    raise BackupAgentError("Failed to get upload details") from err

re-triggering the automatic backup with Nabu Casa clound option disabled, removes that error message on top and its a sucess:
