How to create a full system backup

[Paulo Roncon]

Hi!

 

I need to create a exact copy of a RH9 system. This system has the
following partitions: /root, /swap, and /.

What I would like was to somehow create a "ghost" of the disk, so I
could disconnect the original IDE Drive, connect the "ghost" and the
system work as normal.

If I had a LVM how would it be?

Is there some application or way to replicate the disk, create a mirror,
ghost, whatever?? 

 

Thanks in advance!
