This week I am at the Toronto Mozilla office. With Mike and Alan we were discussing information entropy and backups and devised the craziness of doing a hard drive backup onto paper, using QR Codes.

Alan and Mike did the math.

For one TB, it would take 44 trees, and at 20 pages per minute, it would take 123 days to print the 3.6 millions letter-size single sided pages, at 300dpi, in large-size, using the highest-redundancy QR codes.

Now you know how much information we create and how much it would take to make it last longer than the electronic device it is stored on.
