I'm of the opposite opinion.
Virtual tapes should be used for most large sequential datasets.
Only exceptions are datasets that are required to be read by multiple
subsequent jobs at the same time.
No B37 ABENDs ever, lower cost and much more easily recovered if something
gets "accidently" deleted.
Yes, it is possible to have VTS without real tapes on backend. Some
vendors do offer only "tapeless tapes", with no option to connect real
tape library.
However from OS point of view there is difference between disk (DASD)
and tape (offline storage).
Price difference is also worth to consider,

Don't understand why 'offline' backup is considered a difficulty when going

A very good point. In all of our storage products that we produce (dasd and
