I don't believe there is any way to do a BACKUP command in HDB-DOS
that copies from one virtual hard disk file to another.  Only one
virtual HD is active at a time and you have to issue a DRIVE #n
command to change it.

It would be nice if HDB-DOS were modified to accept both a virtual HD
number and a drivelette number when doing a BACKUP.  Something like:

 BACKUP #0,0 TO #1,0

You could use a BACKUP program written in BASIC to do this using DSKI$
and DSKO$, but it would be somewhat slow:

CLEAR 500
INPUT "SOURCE";S1,S2
INPUT "DESTINATION";D1,D2
FOR TR=0 TO 34
FOR SC=1 TO 18
DRIVE #S1
DSKI$ S2,TR,SC,A$,B$
DRIVE #D1
DSKO$ D2,TR,SC,A$,B$
NEXT SC,TR
