Backup Databases using a cron

From Lunarpages Web Hosting Wiki

Jump to: navigation, search

You can set up a cron to backup your MySQL database several ways.

Please note that all scripts for cron should end with a .php extension, and the file should have 755 permissions. You would also need to change the first few variables to those of your site setup.

When setting up the cron job it should look like this:

php -q /home/username/public_html/folder/name.php

Where username is your Lunarpages username and name.php is the backup script you created.
