Thanks everyone -
Reading through the responses, it became clear I should have explained my situation a bit more...my wife and I are cruising sailors, and our 34' sailboat is, (and has been, for the last 6 years), our home. We are normally on the move on a regular basis, though the COVID situation has us in the Florida Keys until sometime next spring, at least. When we were land based, I did the 'hard-drive shuttle' to and from a bank safety deposit box. Unfortunately, that's no longer a viable option.
Another reason I'm looking at cloud storage is the real-world survival of portable hard drives, computers, etc., in the marine (salt-water) environment. And, I was also planning to only keep my most important images and videos in the cloud, as well as on portable drives which I store aboard the boat. The Adobe Cloud was an option I hadn't considered until seeing it mentioned in some of the replies. The more I consider it, that's looking to be my best option.
I am very much aware of how long cloud uploads and download can take. Another fact of the sailing life is dealing with sketchy Wi-Fi almost all of the time. Fortunately, the marina we're in has amazingly good signal...unheard of in our experience...and so, we make the most of it while we're here. Otherwise, it's a taxi or bike ride to a local coffee shop/internet cafe to work and upload. And with regard to Amazon Cloud Drive, Google Drive/Google Photos, etc., I do use ACD for mobile phone work, but that's it.
Thanks again -
Unrelated to the topic: just curious which marina you are in in the Florida Keys. My nephew is a captain and takes people out on Color Change Charters.
