On one hand I fully believe that ETS is worthy of regular backup and protection from the failures and ephemeral nature of the web medium and server malfunction.

On the other hand I think the main productive output of ETS is not the web site, lots of good information, some of the best overviews and analysis of survival equipment out there, or the forum, as good as it is. Rather the big payoff is in the ideas, concepts and principles impressed upon peoples minds, a way of thinking that transcends equipment and the specifics of any survival situation.
