How to save an installed web server as an image?

Question

ubuntu

There is an OS installed and configured on the machine (ubuntu server).
How can you save the state of the OS in the form of an image so that you can save it to a USB flash drive and later restore it or put a ready-made web server on another machine?

Answer 1

On a running machine.
Wrap everything in an archive (tar). And deploy on another host.
If you need details, I can chew. Did this a few times, no problems.

Answer 2

Boot from live CD or bootable flash.
Using dd, copy the entire partition or disk to another flash drive. You can use Clonezilla
instead of dd
