Backing up (raid systems etc?)

Hey everybody! I am doing some research on backing up etc, and wanted some advice. I have noticed some other threads but wasn't satisfied with the information I found. I am running a reaper setup on my Open Labs Neko (timbaland edition), and I also run a protools system off of my Neko too. I mainly use my reaper setup but insist on editing multi track drum sessions in PT. The elastic time function is amazing for drums, and crucial for my needs. ANYWAY, I have three hard drives that I manually update and clone once a week, but need something more efficient. Perhaps a raid system? or something else? Any suggestions? Thanks guys!

On the Cheaper side you could get one of those "WD MyBook" things. There are 1TB and 2TB raid-1 versions that support USB2/Firewire800/1G-Ethernet and sell for under $300 with DRIVES INCLUDED. This is a rapidly changing part of the market, expect much more, for much less, as time progresses. .

Thanks guys 

Thank you for your posts guys! I'll look into all that..
