Backups are always something that every computer user should be doing. I have a couple of methods which I use depending on the types of files. For day to day files, I use a product called Carbonite. I will back up any files you specify with the default being the My Documents directory.
The program backs up your files to a secured site when you are not using your PC/Internet connection.
The product even comes with a 15 day free trial. Cost per year is $50 – a cheap insurance policy.
