I use rsync to backup my desktop (which is mostly used for development) pretty much just rsync /home to a big enough external LUKS drive.
Has saved my bacon a few times, I don't care about incremental snapshots or delta's (though I've used both rsnapshot and rdiff successfully in the past), I'm covering the "if the SSD blows up, how long to chuck a new one in and be back up" case not the "I might need that file from 6mths ago".
I also have syncthing setup via /home/<user>/Shared/{Personal,Work}/ on every machine and important stuff I just chuck in Shared/ and forget about/it's available wherever I need it at any point.
I've had really ornate bulletproof snapshot based backups but honestly for my particular use case they where more hassle than they were worth, rsync does what I want every time and has never let me down.
