Backing drobo 5n to cloud

Hi All

Got a drobo 5N with about 10TB installed of various media andfiles, how ever I have hit a brick wall with regards to backing it up to the cloud.

I have an imac and MacBook Pro, as well as an ipad and iPhone, which backs up to my drobo, however I have no back up solution for my drobo. I have looked at the apps and elephantdrive is just too expensive, and crash plan doesn’t backup the drobo to its servers.

Does anyone have any good working solutions, to backing it up. For the record I’m more worried about photos as I have millions and these can’t be replaced.

Thanks in advance
