On your MySQL Server doing backups you get:
Backups Failing: Dumping MySQL database database_name …. dump failed! mysqldump: Couldn’t execute ‘show events’: Cannot proceed because system tables used by Event Scheduler were found damaged at server start (1577)
Try these repair actions, do one, test, and then do the other one.
mysql_upgrade -u -p
Now test. If that doesn’t work, do this:
mysqlcheck -u -p –all-databases –check-upgrade –auto-repair
To test, use ‘database_name’ and then do ‘show events’.
