Let's say you have two disks.  There's the "system" disk with the root 
partition mounted as / and the "backup" disk mounted as /backup.  If you 
did this:

/sbin/dump -0u -f /backup/rootbackup /

you would wind up with a dump image of your root filesystem on your 
backup disk and it would be called "rootbackup".

That works for me.
