Unfortunately, Google Photos. It's very convenient, but there's this background fear that if my account gets unexpectedly closed, as it happens with Google, there would be no way to recover my photos.

I try to download the Photos data regularly via their takeout tool, but the process is cumbersome. I wish there was an automated way of doing that. I'd even pay for that.

I moved from Gmail to Fastmail, but I still haven't found a good replacement for Google Photos.
