I have configured my production MySQL database with MySQL Enterprise "online Backup" option. The configuration was went through successfully. When the assigned scheduler is try to take backup then i am getting below mention log error from MySQL database.

Everything is OK, like MySQL tables because this is my production database. I have 44 tables in MySQL database and most of the table is in INNODB engine and also there is MyISAM engines.

mysqlbackup failed with errors!

I am unable to find out the exact error from my MySQL error log.


Below is the answer to my Service Request related to the same problem from the Oracle Support.

"This is a known problem, MySQL Server 5.7 is not in GA yet and currently MEB is not supporting 5.7 versions. Developers are working on it".

  • In place of MySQL Server 5.7.5, i had installed 5.6.26 - log mysql community server and able to take "online Backup" as well as "Incremental backup" . Sep 3 '15 at 12:51
