So I got a large 2TB usb 2.0 external hardrive which I have been ripping my DVD collection to and then playing via the new Apple TV. Works great however the collection is getting quite large and I fear what would happen if my drive fails and all is lost. Originally I wanted to do a raid with a Drobo box or something (no idea how it works) but the way the Apple TV works the files have to be assessable through iTunes. So anyways, what is the best way to protect that drive, automated would be the best. Thanks much!
