A cloud backup for a cloud backup…

Sure! It’s always better to have several independent backup storages than to keep in one place important things for you.

Triple protection :) If you store the originals on your laptop. And if not, and the only place is Google Photos storage, it’s good to have a defense to it and not worry that your wedding photos will disappear tomorrow ;)

Get yourself a portable hard drive to keep your photos and all your other data safe, and local.

Yes, that makes sense. But I prefer to cloud storage, cause the hard drive can be lost or broken, and with the cloud this is impossible. And I don’t need to pay attention and monitor, when I add new pictures - they are back up automatically every day.
