To understand "more", you need to know what "was".  Since you probably 
haven't recorded what "was", the approach is hopeless, IMHO.

If you're backing up too much, you must cut out some of the backup data.

A great start!  :-)   If you really have done this, then the only 
recourses are to backup what's important less frequently and to keep the 
backups for less time.  Examples:

* If incrementals are smaller than full backups, delay full backups. 
Instead of weekly fulls, run monthly fulls with weekly cumulatives and 
daily non-cummulative incrementals.

* Lower retention levels. If you keep backups 10 weeks, only keep them 
for 3 weeks.

* Don't mix various retention levels on a tape.

* If you do daily backups, omit 3 or 4 of them.

* Calculate with client(s) have most of the data/tapes.  Worry about 
them and forget the rest.

* If some client machines are "away" from your media server, don't 
duplicate/vault the backup images.

* If you have a gazillion desktops reconsider what is backed up and why. 
Since the system object can be 200+megs, consider omitting it from most 
backups.

If you can implement any of these suggestions, you probably don't 
understand the recovery requirements of your customers.  If you can't, 
then it's fairly easy to calculate the amount of data that must come in 
and resources to handle it, isn't it?

Sorry, I don't understand "going out to our datacenter".

This does not compute with the above "we have excluded all we can".

Sorry this is not much, but we don't have much to work with.  If you're 
new to NBU/DC, maybe a knowledgeable consultant could help you for a day 
or two ... there appear to be several hanging out on this list, as well 
as at Veritas.

Hope this helps, wayne
