Yes, the features are nearly identical and yes, RackSpace Cloud Files is supported. All of our backup products use Akeeba Engine, our cross-platform backup engine. This allows us to minimise the amount of code we write, keep the backup features consistent and ensure the stability of our entire line of backup products. It took a few years to developer, but I'd say it's well worth the time we spent on it :)
