使用codeigniter备份数据库，不会引用插入值（语法错误）

I creating a backup and restore feature for my website and I am using codeigniter as my framework. When I use the dbutil of the framework the backed up file doesnt quote insert values, this is causing an error when I import the sql file to my database because of syntax error.

INSERT INTO `account_client` 
    (`IdClient`, `FirstName`, `LastName`, `Contact`, `Email`, 
    `Username`, `Password`, `Profile`, `DateMod`, `Status`, 
    `suspend_from`, `suspend_to`, `suspend_day`) 
VALUES (8, Remuel, Sigua, 03222212121, remuelsigua@gmail.com, 
        Rem21, $2y$10$hPb/gA6Pyy/6IWO87gJfi.4UIh8pB/GZdBVHxFHahI/fcfwrYUkx6, 
        NULL, 2018-11-17 17:01:06, 1, NULL, NULL, NULL);
