There is a new feature “page_tracking” that helps incremental backup to find the changes blocks and speed up backup and also reduce IO.
I was not able to set it up on read-only-slave server/
I"m getting this error when trying to install the plugin
mysql> INSTALL COMPONENT “file://component_mysqlbackup”;
ERROR 1290 (HY000): The MySQL server is running with the --super-read-only option so it cannot execute this statement
Any idea how to overcome this issue ?
