Can keywords be stored in cloud?

Well, I just lost all the keywords from my ten plus years of shooting digital cameras. Auto-Update deleted old versions this last round,and along with it all my workspaces and keywords. The workspaces were easy enough to redo, took about twenty minutes tops. But the keywords will never be redone. People, places, project titles, client info, all gone. No, I don't have this as a backup as none of my backup drives have the requisite folders. Of course this is entirely my fault, compounded by my niave trust that Adobe would give any thought to transferring what is arguably some of the most IMPORTANT information from one update to the next. 

So, before I bother moving forward keywording as I have done for years with new image files, is there any means of having this information stored in the cloud so that it will not be deleted by mistake again? If not, I will not bother doing any keywording at all.
