How to copy or "Ghost" a drive

[bryant]

But when I want to re-ghost every month or so the entire C: hard drive, would one have to redo the whole operation again.

I am not sure if this got answered.

Reason for asking is that a lot of different databases add material (data) to them over the course of a month?

And how is this process done with Norton Ghost (updating every month which may mean whole new copy)??
