Dumping multiple partitions to a single tape.

[Mark Parris]

Hardware & Software: 	Ultrix 3.0 	MicroVaxII

Background:
We currently do remote dumps across the network using the rdump command 
to backup our system.  This works fine, but it seems to be wasting a lot
of tape.  We're using 6250cpi tapes and dumping one filesystem/tape.
There's usually about 75% of the tape left unused after each dump. 

MY QUESTION: 
Is there anyway to get dump to dump multiple filesystems to a single tape?
Of course we would want standard recovery to work.  I've heard some kind
rumor of an undocumented switch on dump that allows one to do this but
that's all of the info I have.   

Please e-mail.  I will summarize.
