You can backup the SYSTEMOBJECT using a specific management class to only 
retain a few active copies, we went from 160 to 10, has helped quite a bit.  
You can search on SYSTEMOBJECT in the mailing list and there should be a 
conversation pertaining to SYSTEMOBJECT Retention.

DOMAIN      -SYSTEMOBJECT

I turn it off for all my remote clients, so I don't have to pull all that
data across the wire every single day.<

However, if you *do* turn off system object backup, and you have to do a full 
BMR, you're going to be in a world of hurt.
