servyer image

I'm trying to make an image of a server to replicate it in another computer. Does anyone know how am I going to do this? Should I just make ISO & burn the directories (/var, /root/ etc.) in DVD and dump it in the new server? Is there any tool that can make life a bit easier?

First off, unless the servers have the exact same hardware this is a bad idea. If you still want to do it, I'd recommend you connect the new server's hard drive to the old server, and do something like this:

Code:

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

It will be relatively fast, and will be a perfect 1:1 copy. If connecting the new hard drive in the old computer is not feasible, you can make an image file like this:

Code:

dd if=/dev/hda of=/image

Transfer the file to a computer with the new hard drive in it, and

Code:

dd if=/image of=/dev/hda

I tried

Code:

dd if=/dev/hda of=/image

but it goes in an infinite loop until the disk fills up.

I also tried tar gzip the drive ( / ) and then extract it in the new disk but that doesn't work. Is there any other way I can get an image of the disk?
