These options are the same as for the mysql command. When present, they must be specified ahead of any other mysqlbackup options.

--print-defaults           Print the program argument list and exit.
--no-defaults              Don't read default options from any option file.
--defaults-file=PATH       Only read default options from the given file.
--defaults-extra-file=PATH Read this file after the global files are read.
--help, --verbose, --version, --debug : Common standard options.

--force              Force operations such as: overwrite files,
                     create backup directory.

By default, some of the “apply” operations halt rather than overwriting any user data or log files. --force allows overwriting InnoDB data and log files in combination with the apply-log and apply-incremental-backup options, and replacing the image file in combination with the backup-to-image and backup-dir-to-image options. For all other mode options, the --force option is rejected.
