Well, Google Photos shouldn't be considered a "backup" solution to begin with. Never mind that both Google and Apple scan the content in their respective services, but there's just no guarantee that they don't modify the data on cloud. "Oooh guys, we just invented a revolutionary new photo compression algorithm! Also hosting data is kinda expensive! So pay up if you want your originals." ...and there's occasional reports that these services just straight up corrupted some old files while no one was looking at them. Good going.

I just treat my Android phone like any other camera I own and use. Copy the files from phone to PC and from there to my NAS, and I use ACDSee's DAM functionality.
