I’ve just heard about this cool WordPress plugin WP Sync DB which you can use to easily sync two different WordPress installations – your local machine with your staging or production server for example. Check it out! Together with updating your files via version control it is now pretty fast to deploy to your live and staging servers with almost no downtime.
Another great advantage is that you can have your local machine pull or push the information from the live server. This means you can test your project with real data!
