Are you using standalone backup here, or the BACKUP available from the 
VMS prompt?  ISTR that standalone backup supplied with VAX-VMS doesn't 
offer the full functionality of the command line version.

I think if you use the virtual tape emulation of LDDRIVER to mount an LM 
device you should be able to copy from physical tape to virtual tape.
