How To Back Up An Ubuntu 8.10 System With SystemImager

How To Back Up An Ubuntu 8.10 System With SystemImager

SystemImager
lets you create images of your Linux installations. To do so, you need
an image server (should have enough disk space to store your images)
and a so-called golden client (i.e., the system of which you want to
make an image). This means that you have to install some software on
your image server and on your golden client in order to run
SystemImager. This tutorial shows how to install a SystemImager server
and a SystemImager client, both using Ubuntu 8.10, and how to
create/update/restore/delete images.
