Hi

If you want to create a disk image and use the same image ur underlying hardware should be same. If it is use fthe foll
:

dd if=/dev/hda of=/de/hdb

In this command your system should have 2 disks and once the command is complete remove one of the disk and boot the other server using that.

However if u want to just backup the linux box there are several tools available but if u want to have a "bootable backup" you need imaging.

Cheers

Shalom,

There is no ignite/ux for RH.

Sorry.

Alternate tools:
http://www.mondorescue.org # can make bootable cd's based on iso images. Free.
http://www.acronis.com # Not free, can make bootable cds

You could also use the software called partimage, which is a Norton Ghost like solution. One of the easiest way to use it is to use a bootable CD, like the one from http://www.sysresccd.org/Main_Page
