In v3.4, you're limited to two copies regardless of media type.  So your
disk copy is one and the new tape copy is the second.  Once one of these
copies is expired, you're free to make another copy but no more than two at
any point in time.

With v4.5 & up, I think the limit is 10 copies.

   The short version is that you set up a Storage Unit on a big chuck of
disk space, and run your backups there. Later on, you _duplicate_ those
images onto a tape Storage Unit. You can then expire the images on the
disks, or keep them around for a while in order to restore faster.

   It was in an email to the list from Mark Donaldson last September. I can
email it to you offlist if you like.

   Easy: when you create the STU, it's not a Media Manager STU, but a Disk
STU. <HomerSimpson>Mmmmm, disk stew.</HomerSimpson>

   No idea. Is this a problem? :7)
