However, I will point out first that dump and restore are utilities that have been around the Unix/Linux world for a very long time, rather than something from the M$ world. The issue of how to restore/copy a system installation is open to discussion these days. I have recently been in a situation where duplicating identical machines is done conveniently with dump and restore. I have also been in situations where installing or reinstalling a system of slightly different configuration is easily accomplished via kickstart. It mostly depends on the situation to be addressed at the moment, and the tools available. For instance, to perform a one-time installation when you do not have kickstart set up on your network is a significant amount of work, and may not be worth the effort of kickstart set-up. This is one of the benefits of decades of development. More tools are available to handle the installation requirements. > Valeri > > > > > I usually use dump/restore commands.
