Ah, bigcorp with the Pick-Up Artist model of consent: keep asking until they relent.

I find Google Photos asks me once every update. I got a Pixel 9 with 1 year of free Gemini Pro (or whatever version it is, their offering almost feels like Windows 7 Home Enterprise Ultimate), but because of their nagging about the backup I loathe to give them money to subscribe to Gemini beyond that.

I have a Google Pixel 1 I got from eBay, with "lifetime free photos backup", sitting plugged in on a shelf. Every evening my main phone syncs photos I take on it to my NAS, and another app copies the images from the NAS to that Pixel phone, which then backs it up to Google Photos... it's my finger to Google for being the enshittfiying assholes they are
