Exactly. Print out the whole thing, doesn't matter how many characters if you're trying to recover from something this drastic, and follow the general backup rule of "If you have 1 copy, you have 0, if you have 2, you have 1...." Put copies in different flood plains, ideally different parts of your country or the world.

While its not always possible, it's a good idea to use at least two completely different backup methods, avoiding single points of failure like in this case. For example, use a logical volume manager to make frozen copies of your filesystems, and back those up using something low level.
