Exclude Pagefile and Recycle Bin/Recycler

In an attempt to fight the ever-increasing need for backup storage, I am playing with the exclusion list.  Excluding *Recycle.bin* and *Recycler* (not sure if I needed to list *Recycler*), on a test server, bought me 5MB of savings.  That's not worth the effort of updating 1300 clients.  What is excluding the pagefile.sys going to buy me?  Am I oening myself up to future issues by excluding pagefile.sys?  Has anyone taken successful steps at reducing the backup size of individual clients?  I'm open to suggestions, idea, thoughts, rants, and/or NetBackup memes.

Thanks in advance,

Randy
