FAQ: What files do I need to backup the Safeguard server?

It depends on your server configuration, where mysql is set to store the data, where Apache www is stored, and so on.

The www root folder is where the admin scripts are stored.

For backing up the database use a front-end tool like phpmyadmin or similar, and schedule a cron job for a mysqldump.  It is better to do this than copying the entire mysql setup from disk so you can restore the database at a later stage.
