title: mysql replication insert only
body: <p>I have several slave dbs replicated from the same master db, however, for one of the slaves, i would like to keep it as a backup db, which will never have rows updated or deleted.</p>
  
  <p>basically the purpose is to have a backup db with all rows stored by using the replication(mysqldump is waaay slow to do the backup), no update/delete query get replicated, insert query only. i know there will be some conflicts going on no doubt, but still wonder if any filtering options on statement/query on the slave end or any other solutions.</p>
