What is the difference between "image" and "backup"

While I remember, creating a system repair disk won't go amiss.

You can't re-install Windows with it, but it does let you boot into Windows to repair or recover your system if you don't have a Windows DVD.

System Repair Disc - Create

What recovery disk are you talking about?

in OneKey Recovery I can create a recovery disk, but I can also create a recovery disc in windows 7.
So what's the difference?

A system repair disk is a mini standalone Windows OS to run repair tools including access to a command line prompt for running command line tools. You boot it from the System Repair DVD you make. It very importantly is used to reimage your PC's existing or new HDD from an external HDD stored image.

It's a must have.

Your OneKey Recovery creates a recovery disk that will allow you to re-configure your computer with the factory-installed system the same as when you first bought the computer.

The Windows repair disk does not re-install Windows, but as already mentioned is an essential tool to access Windows recovery options such as restoring from a system image and repairing the Windows boot record.
