I would encourage you to familiarise yourself with LDDRIVER.  It is very 
handy for creating scratch disks on the fly for testing.

More importantly LDDRIVER gave me an alternative backup route when my 
DAT drive failed.  I created some LM virtual tapes (on an NFS share on a 
Mac system where I had more space).  This was before I had a DVD writer 
so I sized each virtual tape so that it would fit on a CD.  With a bit 
of care the LM SWITCH command can be used to switch tapes from one 
virtual file to another, similar to the way you would change physical 
tapes.  If you are stuck with only one VMS session you either spawn your 
backup command or stick it batch so that your single session is 
available for issuing the SWITCH commands.
