        I've actually wondered about this. I've been told that in the
mainframe
        world, they are able to make two copies of the same file at the same
time,
        i.e., mount two tapes, and stream the file off of disk to both tape
drives.
        I'm told this incurs quite a bit less than the 2x overhead you would
        normally expect from making two copies.  Does anybody know of a way
to get
        ADSM (or even just AIX) to do that?

        Did you at all consider COPYPOOLs? Or are you unaware of them?

        Copypools were made for DR.  Just setup a rotational plan to send
        tapes out as the fill up and reclam on weekends all the ones that
get too
        fragemented during the week.

        Call me if you liked to here what we do.

        On the other hand if you need something more 'archival' in nature
then use
        backupsets.

        or both if you need both!
