Many phones function this way now, automatically uploading photos to Google's or Apple's servers. I know it's not really as good as uploading it to a rogue operator's secret vault in the side of a mountain, but it does provide the basic protection from device destruction discussed here (and you could probably configure a Dropbox-style private cloud to upload to the mountainside vault anyway (something like OwnCloud may already do this?)). Many professional cameras have wifi capabilities, either as an add-on or built-in, that can be configured to transfer photos from the camera to the phone. You can then set that directory as a cloud backup target and it should take care of the matter.
