Backup Certain Files from Windows 7 to a network location

This has become a little confusing.  I have been trying for a while to backup just office document's, pdf's and a couple other file types from our client computers to their personal network share.

In the past I have used a bat file to accomplish this task on XP but it wasn;t adopted globally.

Since we are now going to windws7 I thought there were more robust systems to handle this, Sync Center and The windows 7 backup system.

Sync Center seems to only work for Offline files which technically is makeing network files avilable offline - This isn't really what I am trying to acconmplish, rather backwards of what I want to do (seemingly anyway)

Windows Backup seems to have options to just backup the person library which is OK, but I do not see the ability to excelude the cumbersome media files and pictures which we do not want taking up space on the servers.

So in short, am I missing something with Windows 7 ability to sync file TO the network and not vice vera, is there a way to make the backup system run with an exclusion files OR and I back to trying to use my .bat file with a schedueled task.

Any thoughts about this are appreciated.
