I have executed a strategy for backup where I stop a slave and do a mysqldump with --master-data. Both master and slave are 4.1.20 My assumption was that the log coordinates in the dump file would provide me with the place to replay the log for a point in time recovery. What I learned today however is that it appears the binary log only captures statements run directly on the slave. Any SQL run by the SQL thread of replication seems only to go in the relay log. This effectively renders the --master-data useless for my purpose. So, I have two questions. 1. Can someone verify that the binary log on the slave is not capturing SQL from the replication SQL thread. 2. If the above is really true, what strategies are you using to backup InnoDB without InnoDB hot backup? Thanks for your time! Peace Boyd
