Carbonite is better in my opinion, especially for small business backup. Hope this helps, take care!

 

For FREE online storage, check out Dropbox, Box.com and SkyDrive. As I recall, the free version provide up to 2GB (dropbox), 5GB (box), 7GB (Skydrive). They also have a limit on max size of any one individual file.

 

Google drive also has 5GB free storage, and is really convenient if you already use other Google services like Docs.
