When you get a blackout the power usually doesn't cut off cleanly, and often
doesn't return cleanly either. Depending on your power supply the voltage could
make several rapid attempts to rise and fall again. This can easily corrupt
files/settings.

The solution is either a small UPS, or a power supply that can hold it's
voltage steady for a long time after power goes.
