After some research I found that it can be easily fixed. The issue occurs because most probably you have created a Shared volume and the VHDX file or Virtual Drive is in the root of the volume. To fix this, create a new folder called ‘Virtual Drives’ or whatever you wish and move the Virtual Drives onto that folder.

Restart the backup process and the issue will not occur
