Using dd over Netcat
I want to clone a VM from OpenStack to a physical CompatFlash attached on my workstation in my private network.
In case of some public networks or internet use “ssh + dd” as described here in NDCHost Wiki, i use netcat because is faster ;-)
A warning !!
Be extremly careful with dd, and triple check your devices names /dev/sdx !!
1. On workstation
Go to your workstation and run this, sdf is the destination disk
workstation ~# nc -l -p 9000 | dd of=/dev/sdf
2. On the instance
On the instance do the following, the source disk is /dev/sda
~# ssh firstname.lastname@example.org instance-01 ~# dd if=/dev/sda | nc workstation.example.net 9000
Usualy i would use screen or tmux on each machine like this, and after detach screen with Ctrl+D.
~# screen -S clone-sda
