mysql backup error after restore
Posted by: Paolo Sestini

I have succesfully backuped up my database using mysqlback.
At a given moment I had to restore it to a backup taken previously.
Since then the Database is running with no problem but when I come backup it up again I get the following error message:


mysqlbackup -uroot -pxxxxxxx --no-locking --backup-dir=/DbRepo/bkp backup


MySQL server version is '5.6.25-enterprise-commercial-advanced'.
Got some server configuration information from running server.

IMPORTANT: Please check that mysqlbackup run completes successfully.
At the end of a successful 'backup' run mysqlbackup
prints "mysqlbackup completed OK!".
