How to copy or "Ghost" a drive

[bryant]

Bob, Do you ghost evrycouple of months.

My question was: Because it asks to completely erase the
ghosting drive before you start (can't have anything on it), what exactly do you do the next ghost copy you make, say next month. Do you have to erase everything clean again, and repeat the same process.

Also, second question: It does ask and recommends that you make a bootable disk, but not sure why if the drive is ghosted correctly. Do you make that boot disk as well?
