Instead of oscillating between RAID hardware and software, all you need is to put, for example, the Dropbox folder into the ZumoDrive. Then, whenever a file is added or edited in the Dropbox folder, the addition or change will automatically synchronizes with both Dropbox and ZumoDrive services at the expense of duplicate storage.
Sounds crazy but practical especially when you want to give an untrusted new online storage hosting service a shot.
