Errno 5 for scheduled full backups when using download_path to an rclone target

[jamesmacwhite]

Hi. Thanks for your HACS integration, I'm using Auto Backup with a Home Assistant Docker container (Core) to have more control over the backup options. I seem to be getting Errno5 on scheduled backups. If I run the scheduled automation manually it seems to be OK.

Stacktrace from the logs.

2024-05-30 03:04:24.506 ERROR (MainThread) [homeassistant] Error doing job: Task exception was never retrieved
Traceback (most recent call last):
  File "/config/custom_components/auto_backup/handlers.py", line 231, in download_backup
    shutil.copyfile(backup.path, destination)
  File "/usr/local/lib/python3.12/shutil.py", line 262, in copyfile
    with open(dst, 'wb') as fdst:
OSError: [Errno 5] I/O error

This is my backup automation yaml:

service: auto_backup.backup_full
metadata: {}
data:
  compressed: true
  download_path:
    - /backups
  keep_days: 30
  name: Automatic Backup {{ now().strftime('%a, %-I:%M %p (%d/%m/%Y)') }}

I have the path /backups within the container mapped to a path on the host machine which is a rclone Google Drive target. The rclone target is working and I can read and write file to the Google Drive configured.

I've tried adjusting some rclone properties, but it doesn't seem to fix the issue.

Is there anything I can look at to address the Errno 5 error. I'm thinking it's file handle/path related, but if I run the same automation schedule manually it seems to be fine.
