I have to say I am slightly surprised by this poll result. Many people that I know who has computer don’t know what a backup is and for, let alone keeping one on a regular basis. I guess this poll is biased since most of you visitors are already computer literate and know the value of a regular backup. Still, two people don’t believe they need backup and one doesn’t know what a backup is. May be these three people are just trying to skew the poll result, or may be not.
