Carbonite lost a file folder that was critical to me. The 'service' was terrible. After complaining via multiple emails, they offered a refund of my purchase price. Although this would not compensate the loss of the files, it would be some compensation, so I accepted it. Then they cancelled my entire account! So here's Carbonite: 1) incompetent at backing up and 2) dishonest! I have since switched to Livedrive - so far so good.
