I never even used Google Photos (because, you know), so if somebody could explain more concretely: how do you use it? Is it actually a
backup app (and if so, is it really much different from using a generic backup app or even just syncthing), or does it somehow magically allow you to keep the preview gallery and search on your device, while your actual 200 GB of photos are somewhere in the cloud and the local storage is basically just auto-managed cache, where everything you didn't access in the last 6 months gets deleted? Does it preserve all this additional data Android cameras add, like HDR, video fragments before photos, does it handle photospheres well, etc? I'm asking because I don't even fully understand how the camera app handles it itself, and if all the data is fully portable.
FWIW, I also don't use any fancy collection management and barely understand what all these Lightrooms and XMP files are for. Maybe I should, but up to this day photos for me are just a bunch of files in the folder, that I sometimes manually group into subfolders like 2025-09, mostly to make it easier on thumbnail-maker.
