Hi, Corey, That is a sweeping statement that I think needs clarification. My take on this statement is: Google Photos: True if you select the unlimited option, not true if you pay for the storage. Dropbox: The only compression that they use is perhaps totally transparent data compression on the server side (I have no evidence of that) but they deliver files back to you as you sent them. While originally running on Amazon Web Services, they have migrated to their own multi-location cloud. Backblaze: Although not a cloud service per se, but rather a backup service, I believe they do de-dupe your files and only save one copy, but otherwise they give you back what you sent in (again, they may use sever side lossless data compression). Amazon Web Services/Glacier/etc: These services give you back what you put in. There are many others, but these are some I've looked into over the past few years. At the moment, I use the first three and had long had a thought about using AWS/Glacier. I don't know a good solution that meets the OPs requirements except perhaps splitting items between a service which allows passwords (paid service) and the Internet Archive for the free-access stuff.
