Yes as an example of this use the lddriver that is included in VMS 7.3-2
and beyond for testing. It is a container file just like the virtual

FWIW I'm successfully using LMDRIVER to do "tape backups" to container
files held on an NFS volume. Since I haven't managed to persuade my Mac
to host as NFS V3 (NFS V2 only supports files up to 2GB), I've set those
tape container files at 700 MB so I can copy them to a CD apiece.

LMDRIVER handles continuation tapes nicely using the SWITCH command. In
other words you don't have to muck around calculating how many files
will fit on a CD. Selective restores are wonderfully fast :-)
