My scenario:
- I have backed up my shares to USB drive.
- Example: Backup "/Volume1/media" to "/Volume1/@usb/usbshare1/media"
- Meanwhile I had to delete all my discs (see issue with too small system partition).
- Now I wanted to restore the "media" folder to Volume1. This was not possible as I cannot choose "/Volume1". So first I had to re-create the share folder "media" and then I could only choose "/Volume1/media".
- As a result the restored media folder will be created as "/Volume1/media/media" and not as "/Volume1/media".
