Google for contacts and small stuff. Photos get copied to a home server which itself gets backed up. I've used rsync front-ends, non-standard apps which I don't like (PhotoSync). It's been plain SMB shares accessed through CX Filebrowser recently, I haven't cared to get fancy. I'm always using this SMB share with various devices anyway because tons of things "just work" like VLC on Chromecast.

How do you copy the photos to a home server?
