Carbonite is a great website to consider.
For $59 dollars a year, you will get unlimited space to have your PC or Mac computer backup automatically and securely when your computer is on. Your photos, music, and files are accessible wherever you go. Moreover, if you have an iPhone, iPad, iPod touch, Android, or Blackberry smart device, they also have apps available for those, making it easy to share anytime, anywhere.
You can sign up for a free 15 days trial offer, and if you decide to buy this service, mention the code BLOGAD you will receive two free months. You won't ever have to worry about losing file, contact emails, photos, or other important information again if something goes wrong with your computer.
For less than $5 dollars a month, I'm seriously considered this option, especially since I have access to my files wherever I go, which means I could post photos, or publish my writing to my blog even when I am not at home. This is an advantage to have to online backup.
