Touched on not very long ago...
     #1) I do FULL backups daily... I use an administrative event to issue:
        BACKUP DB TYPE=FULL SCRATCH=YES DEV=3590DEVC
     #2) To get those tapes back I have another admin sched event to issue:
        DELETE VOLHIST TYPE=DBB TOD=today-7
     this will delete all DataBaseBackup records older than a week...
     Now I am using a 3494 ATL w/ 3590's and I've checked-in my tapes as
     scratch so when the records are deleted adsm returns the tapes back to
     scratch status for re-use for anything.
     You are getting the tape in use 'cause it knows there is a DB backup
     on it and THANK GOD it won't let it be written over! to clear that
     just delete the volume history record of type DBB for that tape...
     checkout the "DELETE VOLHIST" to see exactly how it will fit your need
     under OS/2 and your tape drive / library use, volume availability to
     adsm... all that stuff...
     Hope this helps...
     later
          Dwight
     PS and even though my full DB Bkup takes over an hour on my system
     with the 9+GB DB I still do a full ;-)

I recently upgraded to version 2 (running on OS/2).
One of the first things I read about was protecting the server. I
noticed the Dump DB was superceeded by the Backup DB command. The
problem I am having is re-using tapes that contain previous Backup
DBs. On version 1 I was rotating 4 tapes for Dumps. Now on Version 2
when I place a previously used tape it says something about "tape
alreay in use".

When I first got this error (when the tapes had the Dumps from V1) I
deleted the tapes from the volume history, however I am looking for a
better way of reusing the backup db tapes. Indicating either scratch
or volume name didn't seem to help.

Also is there a way to append to a tape the incremental or do each
incremental have to go on their own tape (which is what it seems).
