If you want to make a COMPLETE backup, you need to add , --all-databases.

Like this

mysqldump -uUserName -ppassword --all-databases --routines > "fulldatabase.sql"

Note that you dont need spaces between -uUserName and -pPassword.

Also, if you are using a PORT in Mysql you must define the syntax like this

mysqldump -uUserName --password=password -P yourportnumber --all-databases 
--routines > "fulldatabase.sql"

This ensures all stored procedures are also dumped to the file.

If it's an entire DB, then:

$ mysqldump -u [uname] -p[pass] db_name > db_backup.sql

If it's all DBs, then:

$ mysqldump -u [uname] -p[pass] --all-databases > all_db_backup.sql

If it's specific tables within a DB, then:

$ mysqldump -u [uname] -p[pass] db_name table1 table2 > table_backup.sql

You can even go as far as auto-compressing the output using gzip (if your DB is very big):

$ mysqldump -u [uname] -p[pass] db_name | gzip > db_backup.sql.gz

If you want to do this remotely and you have the access to the server in question, then the following would work (presuming the MySQL server is on port 3306):

$ mysqldump -P 3306 -h [ip_address] -u [uname] -p[pass] db_name > db_backup.sql

You can specify mysqldump to take entire backup as :

mysqldump -u root -p --all-databases > alldb_backup.sql

and if you think dump file size is too large you can export in ZIP format as well:

mysqldump -u root -p --all-databases | gzip -9 > [alldb_backup.sql.gz]

backup: # mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql

restore:# mysql -u root -p[root_password] [database_name] < dumpfilename.sql
