Terry,
Do a google search for fun plug. There are a few tutorials on this item and it's failry easy. I don't recall if R-Sync is part of it but if so, that would greatly help out your backup issue as well.
Oh, and even though I say it's easy, it still requires several hours of reading before you take the plunge. Also, if you do want to try out fun plug, I recommend you remove your real hard drives, install a single test drive, load fun plug and test it out. You can always put back your old drives. Also save your configuration before you start.
