Backing up your data has to be something you do. A hard drive can go out at any time without much warning. I have had quite a few friends come to me after losing pictures, videos, music, financial documents, and tax records from a computer hardware failure. There is no reason to risk these important files with how easy it is to backup your computer these days. Years ago, it was much more advanced to setup an automated backup schedule. Now, anyone with a basic understanding of computers can do it.
