PS: A power outage while doing a backup might damage parts of the
original as well as of the copied data. Unlikely things happen, too. It
might be possible to repair such corruption, but it might take weeks to
do so. By random two drives could fail completely at the same moment,
without any chance to recover data. Disasters often happen through a
combination of unlikeliness. A lot of issues aren't unlikely at all.
