Nortons Ghost Continuous Backup

I Currently Use Nortons Ghost 11.5 to Backup My O/S as a Disk Image File to an External HDD.

I Execute this from Bootup of a flash drive and save my image to a usb hdd.

This works Fine.

However I have just Added a Backup HDD to my PC and I thought it would be good if I had some program that could Automatically Backup My System.

The Type of backup I want would be A Realtime Copy of my C: Drive which Contains my O/S.

In the event of a Failure I could attach my usb flash drive with nortons ghost 11.5 on it and Burn back the Current O/S Image from my Internal Backup HDD.

Could someone recomend a backup program that could do this.

Cheers, John.
