Hardly a huge machine.
And yes you're right, since there is no hardware, there is no hardware
compression.

In one of several possible configurations, this is true.

You CAN setup the Falconstor VTL to use barcodes different from your
physical tapes, then use Veritas' Vault or ITC or anything like that, to
write two copies, one to VTL and one simutaneously to tape, or to write
to VTL, then use Vault to dup to tape.
Lots of options.
