What is the best company for simple archive and storage in the cloud.

Yes, I moved to iCloud a while ago. Yeah, I realize that time is running out for my items stored on my MobileMe iDisk!! Has anyone found a company that offers cloud archive and storage with good encryption? I am really not interested in sharing of any sort. Once I load it up, I will remove it from my computer. I have no intention on downloading these files to any other computer or iOS device. I will also store it locally on an external device as an additional backup.

Yes, I know about Box, Drop and the other popular ones, but again, I am don’t want sharing to be the selling point.

Any help much appreciated.
