Can't backup with MariaDB Console

I am trying to take a backup of a database. I open up the MariaDB client console on windows 10, enter root password and then enter this:

MariaDB [(none)]> mysqldump database_name > backup.sql;

It returns this error:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'mysqldump database_name > backup.sql' at line 1

What did I do wrong?
