Hi All,
Thanks for all your suggestion. Just a check, if i have a full backup on the server but due to the different specs of the hardware so i am unable to do a bare metal restore, can i just dump all the folders under /var/lib/libvirt which also includes the images folder? Will it work that way?
Here is the folders in libvirt:
[root@pop-kvm-web libvirt]# ls boot images iptables network qemu
Thanks!

If you do it often, you might consider listening for ssh connections on a separate port and using tc to keep things from getting out of hand:

+1 for dd + nc over ssh if necessary.
This process can and probably will saturate your ethernetinterface, so
depending upon the amount of traffic the box pushes on the public interface the size of the partition and other factors, sometimes i add a crossover cable between unused interfaces on the 2 boxes and run the process over that interface, so it doesn't impact the running vms.

I've had good success using dd and nc (netcat) to copy the contents of

was
successful with a md5sum or sha1sum of both the original and copied
disk.
