incremental backup in codeigniter

Question

I am using this function for getting full backup of my mysql db.

function backup()
        {   


            date_default_timezone_set("Asia/Kolkata");
            $date  = date("d-m-Y, g:i A");

            $folder = "application/backup";

            $prefs = array(
                    'tables'      => array('table1', 'table2')
                                 );


            $backup =& $this->dbutil->backup($prefs);

            write_file("application/backup/backup $date.sql.gz", $backup);


        }

But I need to get the Incremental backup of my mysql database hourly in codeigniter. What are the changes required to this code for getting the incremental backup?.

Answer 1

Codeigniter Database Utillity Class doesn't allow you to make a Incremental backup of the database. If you need that you should create a custom library for that. Library should be able to run sql commands. Please read for details about Incremental backup in mysql: http://dev.mysql.com/doc/mysql-enterprise-backup/3.7/en/mysqlbackup.incremental.html

Answer 2

here, maybe you need to try this one.

ob_start();

// Generage HTML page here
generate_full_html_page();

// All magic goes here
$output = ob_get_clean();
ignore_user_abort(true);
set_time_limit(0);
header("Connection: close");
header("Content-Length: ".strlen($output));
header("Content-Encoding: none");
echo $output.str_repeat(' ', 10000) ."\n\n\n";
flush();

// Now page is sent and it safe to do all needed stuff here
cron_task1();
cron_task2();

i read this interesting technique from http://a32.me/2012/01/do-php-cron-without-cron-available/. may be you can modify your code base on that tutorial.

hopefully help you.
