Our new 820 came with one.  Our old system had two 3490's that held
six tapes each.  Our backups took 3.5 hours and we were running out of room.
Now the backup takes 55 minutes and we could back up every day for a week
on one tape!

The downside - restores are SLOW!!!!  So slow, I thought we must be doing
something wrong.  How slow?  About an hour to restore a file located toward
the end of the backup with *search.  About 45 minutes if you specify the
sequence number, but the only way to know that is to do a dsptap - and
that takes 20-25 minutes.
In fact, restoring all user libraries does not take much longer than restoring
just one file (if the file is near the end of the backup).
Great for backup - but do not put a lot of data on the tape and use it for
a lot of interactive restores.
Funny thing - the network guys were so impressed that they bought the
pc version (same thing but uses 'low voltage scsi?') and thier backup
AND restore times are blazing quick.  Go figure.
