I would like to follow up and ask if the issue still persists? Our team suspects this might be related to permission settings: if “Advanced Folder Permissions” is enabled, it’s possible that the new user “photosuser” has not been granted access to the entire path: /myfiles/backup/photos.
If any folder along this path lacks proper authorization, it will prevent access to the target directory. We recommend re-verifying the settings for each folder level. Thank you!
