[Simh] VAX Tape Emulation?

[Johnny Billquist]

Then I must have misunderstood the usecase. I thought you were looking at preserving a bunch of tapes from a future failure of the hardware.

Are you then looking at ways to perform backups of a physical system to virtual tape?

I would probably give the virtual machine a really big disk and run backup to that remote disk and not try to play with remote tapes.
