Does anyone have a decent automator workflow for rsync or one of its GUI alternatives?

I'm trying to do mass backups at work and I'd like to think that someone out there has already done this to save me a some time and effort.

Thanks in advance!

Edit: What I am trying to do is backup just the Documents folder on roughly 25 different Macs to an SMB share. I need the process to be automated so it runs everyday. This is not my ideal solution but, it's what my bosses want. If it were up to me we'd be using SuperDuper! and be done with it.
