++ vRanger not enough disc space - adjust file scan++


we are saving in vRanger to a repository/volme with 2.8TB of free space. Unfortunately a job failes with the message seen below.
It is about a volume of a server with a capacity of 3.6TB but it is no data on it. How can I setup vRanger to check the current amount of data to back up?
In this case this would be 0 and the job would run.
