What is the hardware like?
Are the two servers identical? Do you have hardware raid? I.e remove the member raid1 disk and insert it into the test server, while inserting a replacement drive in production (system should be off during removal even for hot plug drives)
Is virtualization a consideration rather than to a physical server? P2v from VMware.

I use multiple tools to image linux system only (my best one is mondo) ,

1- use Mondo Rescue to clone linux systems:
http://www.mondorescue.org

2- You can use dd also. dd if=/dev/somedisk of=/dev/somedestination

3- rsync scripting

4- netcat
On the source server: (cd / && tar -cvf - ) | nc 192.168.1.2 2000
On the destination:: nc -l -p 2000 | tar -xvf -

5- http://sourceforge.net/projects/g4l/

mondo its only for linux distro, in order to image your system and create bootable CD/DVD download mondo for your distro

assuming that kurajesh meant a real (binary) image, then tar, rsync (and probably Acronis and Clonezilla too) are the wrong tools, as they make "copies" of the data in the filesystem

As said, Linux covers the basics of using dd to clone an entire disk or partition. You can also use tar, dump, or cpio to backup an existing system and restore it to another system. There are a good number of guides published on the net that can guide you through the tar/dump/cpio backup and restore process.
