There are several UPS types available, off-line (switch to battery when
the power goes down, but bypass as power is there), off-line with
monitoring for irregularities, and on-line. El-cheapo off-line aren't
supposed nor able to suppress spikes. Which one do you use?

Does ext2/ext3 checksum or timestamp meta/administrative data so it can
figure out if a block contains garbage at all?
