For anybody reading this....
I spoke with an Adobe tech / called this one in / and after much discussion, turns out that Preferences and Workspaces ARE saved to the cloud, but not in your direct access section of your cloud. You upload them, but you can never see them, or confirm that they were uploaded.
I disputed this because when I reinstalled my AE after wiping it clean, the Pref settings were not in the cloud. There is no real solution to this, other than, I got screwed by relying on this mystery cloud.
After reinstalling manually all the pref settings, I found the folders locally where the settings are kept, and simply manually backed that section up, thus, not relying on this mysterious section of the hidden cloud that either works or doesn't.
Here where the Preference files are located in your computer:
After Effects:
C:\Users\(your username)\AppData\Roaming\Adobe\After Effects\17.5\
Premiere Pro:
C:\Users\(your username)\Documents\Adobe\Premiere Pro\14.0\Profile-(your username)\
Media Encoder:
C:\Users\(your username)\Documents\Adobe\Adobe Media Encoder\14.0\
Of course, when you reinstall the programs, you can migrate your old settings to the new install.
But... if you want to keep real back ups, I wouldn't rely on the cloud at all. It's never there when you need it. (I'm not alone on that one) So keeping a 2nd back up on your own computer will give you peace of mind.
OK, all finished with this one.
Thanks again for your comments and advice.
