How to Restore using VTL instead of Physical Tape
When you open up the Restore window... you will see a "Source" tab... there you can specify what device to use.. whether it be physical or virtual... by clicking on "Specify a Device", then you'll see all your available devices there.
This method can be used by all platforms (Windows, Linux, Unix, etc)... via the NVGUI, it "can not" be used via the Mac NVAdmin GUI... you will need to use X11 to launch the NVGUI Console in order to utilize the "Source" Tab.
