It is observed that a vRanger VM will report as a Physical Machine in the task log, which does not allow the HotAdd transport method to run properly, therefore the backup fails with "2760 (You do not have access rights to this file)"
Task log of the backup job will say the following:
"Local machine is a physical machine"
Instead of recognizing vRanger as a VM.
When a VM is created with EFI boot option, the BIOS information changes causing the vRanger check to believe this is a physical machine.
Create a VM with BIOS boot option.
Waiting for a fix in a future release of vRanger.
