Exchange 2007 Backup Issue using NMM

We have been using Networker Module for Exchange 5.2 for quite some time for Exchange 2007. And we are now in the progress to upgrade to NW8.2.3.5 + NMM8.2.3.5. I have updated the configuration as below at the client property ( Standalone Exchange 20007 on Windows 2008) . The Exchange has D drive for Database and E drive for logs. I am getting the error like below. Any idea why. Your help is greatly appreciate. Backup Server is also on NW8.2.3.5.
