I, too, have found freefilesync to be the best option so far for windows. Changed everything over from Synctoy recently. (I mirror everything I want to backup to a home server, then do cloud backups from there using crashplan.) I may have to give this a try, although it would be nice to see some figures on just how much faster it is, to see whether it would be worth it.
