##### Notes #####
* (optional) 5th parameter: to backup specific tables only,like: array("mytable1","mytable2",...)
* (optional) 6th parameter: backup filename (otherwise, it creates random name)
* IMPORTANT NOTE ! Many people replaces strings in SQL file, which is not recommended. READ THIS: http://itask.software/tools/wordpress-migrator
* If you need, you can check "import.php" too
