Partial restore from SMB backup fails with "await_home_assistant_restart", local restore succeeds

[Trzinka]

Describe the issue you are experiencing

I am experiencing a reproducible issue restoring Home Assistant backups stored on an SMB network share.

The same backup restores successfully when copied to the local Home Assistant backup storage, but fails when restored directly from the SMB backup location.

The restore process starts normally, extracts several folders, stops the Home Assistant container as expected, and then eventually fails with:

Restore <backup_id> error, see supervisor logs

During failed restores the frontend reports:

await_home_assistant_restart

The exact same backup succeeds if I first copy it locally and restore it from there.

This suggests the backup archive itself is valid and the issue appears to be related to restoring directly from the SMB storage.

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

Configure an SMB backup location.
Create a full backup (~16.7 GB).
Leave the backup on the SMB share.
Start a partial restore directly from the SMB backup.
Wait until Home Assistant stops and the restore reaches the restart stage.
Restore fails with "await_home_assistant_restart".
Copy the exact same backup to the local backup storage.
Restore again.
Restore completes successfully.

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

Partial-Restore <backup-id> start
Restore folder ssl
Restore folder share
Restore <backup-id> starting stage home_assistant
Stopping homeassistant application
Cleaning homeassistant application

...

Restore <backup-id> error, see supervisor logs
