Backup fails

Hi,
I mounted a NAS share with Samba, which seems to work. On trying to start a manual backup, I get an error message:

23-07-05 16:23:10 ERROR (MainThread) [supervisor.backups.backup] Can't backup folder media: [Errno 2] No such file or directory: '/data/media/frigate/clips/garage-1688394132.050878-55ahpc.jpg'

The above exception was the direct cause of the following exception:
Traceback (most recent call last):
  File "/usr/src/supervisor/supervisor/backups/manager.py", line 210, in _do_backup
    await backup.store_folders(folder_list)
  File "/usr/src/supervisor/supervisor/backups/backup.py", line 462, in store_folders
    raise BackupError(
supervisor.exceptions.BackupError: Can't backup folder media: [Errno 2] No such file or directory: '/data/media/frigate/clips/garage-1688394132.050878-55ahpc.jpg'

I’m not sure if backup was working correctly some time ago, but I can see backups within the list and even can download them. Surprisingly, the folder on the NAS does not contain the backup files?

I am getting the same on a local backup - same folder - media/frigate/clips and a jpg.

Any solution?
