A number of years ago a Gmail "insider" that I know admitted they had lost customer emails and their policy (at that time at least) was to simply ignore it and not tell anybody because most customers never notice if it is a small number. I think a much bigger scandal is that all major laptop Operating System vendors (Microsoft and Apple) absolutely know when your laptop drive loses files or even is starting to go bad in some cases, and they NEVER tell the customer. I think an excellent product offering would be a 3rd party piece of software and cloud service which was a "verification service". It wouldn't store your files offsite, it would store the name, size, and SHA1 offsite and periodically check that no bits have been flipped on your local drive unless you intended it. For example, a week after I take a photo, I absolutely never want the photo to change. Ever. Same with music I (legally) download.
