Copy partition into image file

Every now and then I have to reinstall a system from scratch, putting the contents on the side. Before I used to go through the system and decide what to manually copy. Nowadays it's so much easier and relatively cheap to copy the whole thing.

In order to copy the partition /dev/sda1 to an image file:

sudo dd if=/dev/sda1 of=image-file.ddimg bs=4M

(The bs size depends on the hardware)

This will probably work gzipping the image on the fly:

#Getting the fingerprints

The one associated to the server's ECDSA public key (the one that's normally shown when ssh-ing for the first time):

$ ssh-keygen -l -f /etc/ssh/

Or, if RSA is negociated, the RSA public key

$ ssh-keygen -l -f /etc/ssh/
