Google completely revamped the desktop Google Drive client this year with the move to Backup & Sync. The initial rollout was a bit of a mess with Google essentially breaking Drive for some people. It eventually worked all that out, and Backup & Sync has been running smoothly since then. There haven’t been many feature additions, but there’s a big one rolling out now. In the latest version, you have more control over which files are synced, and it’s easier to add new folders to Drive.
Google Backup & Sync for desktop gets a big update with ignored file types, photo/video-only sync, and more was written by the awesome team at Android Police.
