Another person learns why you should back up information

This past week at work one of the interns learned the hard way that it's important to do some type of a back up of your computer information either using an online backup service or owning an external harddrive. Her harddive failed and she lost everything, including an interview that she was supposed to turn in that week. I have an external harddrive, and on a regular basis I copy all of my documents, pictures and other important data on to it, but I know several people who prefer using an online service, either way? Backup your data...Once it's gone it can be impossible to get back.
