Quote - When you back up that 1.5 terabyte drive to DVD you will need around three hundred or more disks.

Wow! I can't believe this thread is still active. I only asked what I thought was a simple question, hehe

I plan on buying 2 of the external hard drives and mirroring them. That way if one fails, I'll still have the data on the other. If both fail, well, whoopsie!  

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
