Pardon me for jumping in, but from what I've been able to find, there is NO
WAY to dual copy your ADSM backup tape.  However, if you have a second ADSM
server, you run your database backup there, where it appears as an
'archived' file, and that should be 'copyable'.  The alternative I was given
was "make two backups sequentially, that should be good enough".
