The Neo4j server is registered at port 7474, but the backup server isn't...
you usually don't need to specify port so that the default can be used. What
you'll have to do is:
* Add "enable_online_backup = true" to your neo4j configuration file and
restart the server (if that wasn't the case).
* Use OnlineBackup.from( "localhost" );
and it should work (just tried it).
