If you want a block device copy, I would boot with a live cd (or from
network), and then start a ssh server and dump partitions with cat:

cat /dev/hda | ssh root@client "cat > /dev/hda"

In an running system I doubt you can use dump in such case, but maybe
I am wrong, of course.

Thank you for your reply . Can you please let me know doing the same way as your procedure will make the server & client the same ? Please be informed that I don't have some of the application packages that are being installed on my server . To this end , I want to make my server and client the same but without the need to have that application packages at hand .
