VSM (and VTS) offer simple, application independent duplication for
disaster recovery purposes. When you change jobs from using virtual tapes
to real tapes you have to look at how you're going to duplicate the tapes.
It's one reason to try to keep all your tapes virtual.

It's one of the reasons to use HSM or FDR to make duplex copies. It costs no
more CPU cycles, it fills up the tapes, it utilizes more channels (it's not a
problem IMHO).
If you want to write to tape directly... well... WHY do you want it?
BTW: The biggest VSM/VTS advantage I in my opinion is the number of drives.
It's important in multi-LPAR installation.
