FWIW, I back up to CD and DVD depending on what I want where. Committing to a hard drive, without having a hard backup is not a good idea. Hard drives will fail. When? When you least expect it. And yes, i know I'm going to hear 'My so-and-so external hard drive never gives any trouble'. Maybe not this year nor next but it will happen. Check the RTF specs of the hard drive.

I must remember to remember what it was I had to remember.
