I have been using Google Photos for the past 9 years with no problems. Last year I decided to try out OneDrive, if any of you are using OneDrive, please leave a backup somewhere else or, at least, don't use the selective sync feature, which only syncs some files and folders locally. I used to use the selective sync, then I toggled it by accident, OneDrive created all the folders and was downloading the files when I decided to interrupt it and turn on the selective sync again. A few months laters, I found out that this little incident made OneDrive assume that my newly created empty folders were the right thing to backup and I've lost a decade of photos. Yes, I know it's 100% my fault, I should've known better than to trust microsoft with anything. And let's be clear, when I say trust, I don't mean that I blindly trust Google either, I just trust them to be competent.
