I want to backup my data which is presented in remote server. For that I created .sql file on particular date by using

 mysqldump -u root -h $host $db $table --where="Date='$date'"> db_backup.sql

Due to huge data I cant take the whole backup. I succeed upto creating .sql file from remote server. Now I need to append this data to the existing data in the local server. But if you open the file(.sql) it contains


DROP TABLE IF EXISTS `information`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `information` (
  `Date` date DEFAULT NULL,
  `Name` varchar(20) DEFAULT NULL,
  `Cadar` varchar(20) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Its dropping the existing table and creating the table again. By this I am loosing my previous data. But as per my requirement I need to "append" the data without loosing the previous data. i am dumping the data into my sql using the following command

 mysql -h***.**.*.*** -u root ravi  < db_backup.sql

I removed my ip for security reasons

To make that(append) I commented the above lines manually & run the program. Its working properly. then I tried like this

 open (FILE,"+<db_backup.sql") or die "Could not open file db_backup.s
+ql, $!";
open (RES,">result.sql");
my $total = 0;
while  (my $line = <FILE>)
{
        $line =~ s/DROP/\/*/g;
        $line =~ s/CREATE/\/*/g;
        print RES $line;
}

Due to huge data opening a file and comparing each letter and writing into another file taking too long. Is there any way to reduce my code. I am using CentOS as root user.

Thanks for helping
