Thanks for coming back. I am not sure how to check whether virtualmin uses scponly for backups. I thought virtualmin runs with root?
Here is the full output of a test run. It fails to create the directory because the drive is already full. The drive has plenty of disk space, but due to the failed deletion it becomes full (100 GB drive, one backup is 25 GB)

Before the drive became full I received errors like
