B.4 Expanded Use of Configuration Files

In MySQL Enterprise Backup 3.5 and earlier, only a limited set of configuration parameters were recognized in the my.cnf file, and the backup commands required the paths to one or two configuration files as command-line parameters. In MySQL Enterprise Backup 3.6 and higher, many more parameters are recognized from the configuration file, and the configuration file is automatically located using the same mechanism as the mysqld server. For example, connection settings for the database can now be read from the configuration file rather than specified as command-line parameters. Settings such as innodb_data_home_dir are now determined from the database connection, rather than required to be specified in the configuration file. Because of the enhanced processing of configuration files and additional command-line options, the second configuration file used by the former ibbackup command is no longer needed.
