    db_host="address"  
    db_name="database name"  
    # the directory for story your backup file.  
    backup_dir="/backup"

    # mysql, mysqldump and some other bin's path  
    MYSQL="/usr/local/mysql/bin/mysql"  
    MYSQLDUMP="/usr/local/mysql/bin/mysqldump"  
    GZIP="/bin/gzip"  
      
    $MYSQLDUMP -u $db_user -h $db_host -p$db_passwd $db_name | $GZIP -9 > "$backup_dir/$db_name"_"$time.gz"
