In the tech world there are two kinds of people, those that have lost data and those that will lose data. Hard drives are mechanical and will eventually fail, even the new SSD (Solid State Drive) or Flash Memory have a lifespan of just a few years. Keep in mind that drive failure is just a small part of why backup is needed. If you consider how many businesses have hardware that gets lost or stolen each year as well, the total amount of data lost each year is staggering.
