You honestly won't find a more helpful site for cloud backup reviews. What would take you hours to research on your own is right in one handy site to use for free.
For instance, I checked out a few of the reports and was given an overview of each service. It made it easy to make a decision on which backup company to go with. Check out the site and see for yourself how easy it is to research and find the best solution for your needs.
