Comparing Providers Using An Online Backup Review

My wife and I have always used our computers strictly for entertainment and research.  A few months a go we both lost our jobs and had to do something quick.  We started up an online business and are doing pretty well right out of the gate.  We have been talking about the need to back up our files that are on our computer.  Both of us are pretty bad about doing this so we feel that an online backup would be a good option.  We want to find and online backup review that we can use to compare providers easily so we can make  decision quickly.
