$4.95/month for unlimited online backup @ myPCBackup.com
Our rating (out of 5): 
(based on unlimited data, $4.95/month pricing, ease of use…)
MyPC Backup is our new favorite option for secure online backup.. They offer a wide set of features and are one of the few companies to still offer unlimited storage space (and for a reasonable price of just $4.95/month if you sign up for a 2-year plan, which is half price vs. the regular monthly cost). They also offer a free 2-week trial so you can take a test run and make sure you like how it works.
