This is good advice. We have probably about 75% of our important documents scanned and saved in a variety of places, including on DVD in a fireproof safe. I like the idea of saving to online storage--not so much for the redundancy, but to make it readily available from any Internet-connected computer. Although I always dream of grabbing one of my notebooks in case of a fire or other disaster, it probably wouldn't happen.
I think I'd grab my kids first.
