sudo scp test_database.sql [email protected]:/temp/backup/
Import backup file on destination server.
sudo mysql -u root -p database_name < /path/to/database_name.sql
sudo mysql -u root -p test_database < /temp/backup/test_database.sql

Backup all the databases, enter following command.
sudo mysqldump -u [user_name] -p --all-databases > databases.sql
