Yes, as Chris mentioned... each "backup db" will require a scratch
     tape to be mounted.

     I take full backups daily, also every day just before the db backup I
     do a "delete volhist t=dbb tod=-7"  this will take the 8 day old data
     base backup tape and roll it back scratch.  (so if I happen to not be
     paying attention and I've run out of scratches... I've just free'd up
     one for my db backup to use ;-) )

     If you're going to do incrementals for some of the days... MAKE SURE
     YOU DON'T ROLL OFF THE LAST FULL ASSOCIATED WITH SOME INCREMENTALS
     WITH YOUR "delete volhist" COMMAND!

     later,
            Dwight

My understanding is that each db backup process requires a new tape.
