Data needs to be backed up. Hard drives fail, and if you don't have a plan to protect the files on your personal computer, then you'll eventually lose them. Luckily, data backup isn't very expensive. For less than $100, you can easily keep all of the files on your computer safe and secure.
This is going to depend by and large on the type of internet connnection that you have. If you are still going online with a dialup connection, then you should not look into this type of data backup. It will just take far too long to get your backup done, and during that time, you could easily have just put all the files onto DVDs and give them to a friend for safekeeping. If you have a high speed internet connection - either cable or DSL, then you're in luck and this will not be a problem at all. Just log in, get an account, and upload to your heart's content.
