MySQL Server- 8.0.16 commercial (trial)



[root@exampledb01 logical_backup]# ls -l /mysql_data/config/

I am using mysqlbackup 8.0.16-commercial (trial version) for backing up the databases in my environment.

I have been successfully using the option (--defaults-extra-file) with mysqldump program from community and commercial versions 5.5, 5.6, 5.7, and 8.0. I save mysql user names and passwords (and other login information in the file). When I tried to use the same with mysqlbackup, it does not recognise the option.

[root@exampledb01 logical_backup]# mysqlbackup --defaults-extra-file=/mysql_data/config/extra_options.cnf --backup-dir=/mysql_backup/physical_backup/full_backups/2019-07-21 --with-timestamp backup-and-apply-log

Starting with following command line ...
 mysqlbackup --defaults-extra-file=/mysql_data/config/extra_options.cnf 
        --with-timestamp backup-and-apply-log 

MAIN: [ERROR] unknown option '--~'.

mysqlbackup exit code: 7, Invalid Argument

mysqlbackup failed with errors!

The option defaults-file is very happily accepted by the mysqlbackup program, however, it doesn't do so for --defaults-extra-file option.

The mysqlbackup command reference mentions that the option --defaults-extra-file is acceptable for the program.

I have searched the documentation and googled about it but there is not much I could find. https://dev.mysql.com/doc/mysql-enterprise-backup/8.0/en/standard-options.html

I can proceed with the --defaults-file option in my backup script but I am not sure what's wrong with the --defaults-extra-file option.

    I am not sure this is really a question-- if you are sure this is a defect, you should report it to the bug tracker and either it should documented or fixed: bugs.mysql.com – jynus Jul 26 at 13:12
  • Well, I am not sure if it's a defect. This indeed is a question. May be somewhere down the line I am missing something. That is the reason I intend to seek help from experts instead of directly jumping to the conclusion that it's a bug. – Avinash Pawar Jul 27 at 5:51
