It's simple, the backups are compressed -- they simply remove all those useless zeroes from the binary data.

We should back up the digits 1 and 0 too, just to be safe. In the event of a fire, we want to be able to reconstruct the data, and what will we do if all the 1's get damaged? We'll also have a handy comparison for the 0, so we can insert it back without too much effort when we un-compress the data.
