I’ll give you reliable, but how is emailing photos to yourself for 20 years easy?

I mean I guess sending emails is relatively easy, but doing that for every photo you want to keep — for 20 years — sounds like a ton of manual effort.

Wow, that sounds like a real PITA pattern for a photo backup system, at least for me and my mental model.

Emailing is a decent solution, but which may cost money, unless your phone is connected through WiFi.

I have always failed to see the appeal of a cloud solution.

Whenever I arrive at home, I immediately move all the new photos from my mobile phone to my computer. This costs nothing, except a few seconds of my time and it is perfectly secure.

I prefer to not keep any personal information on a mobile phone, except the mandatory list of contacts.

Or using Syncthing?
