[buug] dd to clone

[John de la Garza]

I have a linux box that is up and running in a production environment.
 I want to reproduce the box for a backup server.  If I want to use dd
to copy the harddrive could I simply do something like:

 dd if=/dev/hda bs=1024k  of=/dev/hdb

or must I know more about the hard drives and do some calculations for
how much data to copy?

hdb is greater than or equal to the size of hda in this case
