     Bill,

     We backup about 15 Novell servers, 4 unix servers and 1 or 2 os/2
     guys.  Colocation is an option we use and has reduced the number of
     tape mounts needed to perform a full restore. But, the main problem
     will be the line speed between MVS and the client vs. the number of
     tape mounts.  ADSM will restore your data but it may take a long time
     (a common complaint from our Novell admin who had to suffer a few
     restores). To avoid this pain, we decided to perform local backups on
     each server and use those tapes as the primary recovery source. If
     that fails (or if the data required was lost a long time ago), then
     the ADSM backups are used for recovery purposes.
