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, both backup and restore operation halt rather than overwrite any user data or log files, either during backup or restore. To confirm that you intend to overwrite previous backup data during a backup, or your existing database instance during a restore, specify the --force option.
