It will ask you for your password and then create a backup of your database. Do not forget to replace <username> and <database> with your values. If you want to backup everything, you can use:

mysqldump --add-drop-database --add-drop-table -u <username> -p -A > databases.sql

It will backup all databases including "mysql" database, which contains various settings like user accounts.

You can restore your database using following command:

mysql -u <username> -p database < database.sql

Simalary, if you want to restore everything, use:

mysql -u <username> -p database < databases.sql

As you may notice, only difference is the name of the input file.
