Backup and restore

I'm running moodle with a mysql database on linux ubuntu server.
I do have an email server running on another linux box and I do have a script that backs that up and then ryncs the file over to an nfs share which I will place below. Perhaps I could crib off this for most of what i want to do.

#!/bin/bash

# Zimbra Backup Script
