I have had a great system for backing up photos for years:

• Google Photos app automatically backs up my photos to Google Photos cloud
• Google Photos cloud syncs with Google Drive
• Google Drive syncs with laptop

So I have copies on my phone, the cloud, and laptop.

Now that Google has de-coupled Google Photos from Google Drive, that flow has been seriously broken. I’ll be switching to Microsoft OneDrive, which is simpler, more integrated into my OS, and and works as expected.
