The standard options are options of a general nature, or options that are not classified under any other specific option group.
Here is a list of the standard options:
The following standard options also exist for the mysql command. Full descriptions for these options can be found in the MySQL reference manual, accessible through, e.g., Server Option, System Variable, and Status Variable Reference. These options must be specified ahead of any other mysqlbackup options, including the rest of the standard 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. It has to be the first option to be specified, if used. --defaults-extra-file=PATH Read this file after the global files are read. --defaults-group-suffix=str Also read option groups with the usual names and a suffix of str.

--verboseoption is used.
--force: By default, some of the operations halt rather than overwrite any user data or log files when told to write to existing files.
--forceallows the following:Warning
For any restore operations, do NOT attempt to restore data to a non-empty data directory using the
