Hello! Adobe's Cloud is not great if you're working with large files on a very regular basis - for a few reasons. 1) You still have to sync the files locally 2) The Cloud is just someone else's computer 3) You're paying a monthly fee to have an inferior experience than to have a local copy of the file
I have photographic data and records from when I was about 13 (when I got my first digital camera) - I'm nearly 40 now, and I would be buying a hard disk every three months if I was paying for Adobe's equivalent of the storage they offer on their plans.
The Cloud isn't back up, particularly when it comes to people's wedding photos, portraits of loved ones who aren't around anymore, or other events that cannot be reproduced.
I am "my own cloud" with my photography stuff, and hold back ups in other locations that regularly get rotated. It is part of my selling points as a photographer - my robust back up methodology!
