I'm surprised more people here don't pay for iCloud for at least the bottom tier storage (50GB). The free 5GB is almost worthless in 2025 for doing nightly backups. I don't back up with Apple Photos but even with "just" app data my nightly auto backups are like 10-15GB.
Even on iPhone there are much better and much cheaper solutions out there (not to mention cross platform) and those have everything a couple of times better than Photos.app and then a bit more. Maybe except Apple's troupe of privacy claims.
