Now having established those definitions, the next thing I would like to talk about is the relationship between availability, business continuity planning (BCP) as well as disaster recovery (DR). From my perspective, I see them as a continuum -- on one side you have availably; systems just simply must be up and operational -- and as you start hedging against or protecting those assets against outages or unexpected failures, you move toward business continuity. Now, we all realize that with the physical constraints in today's environment, you can't protect against all risks. In that case, even if you could, you don't want to. A lot of times the assets you are protecting and the costs associated with protecting them, if they are not commensurate, it does not make sense to provide that level of height and availability. But systems will eventually fail, and when they fail, that's when you actually get into the aspects of recovery. But once again, I see them as a continuum. Also keep in mind that there is a direct relationship with the cost of protecting against failure as well as the time associated with recovery. The longer time you have to recover an asset, the cheaper overall it is going to be to provide that level of restoration. Now, as the cost of disruption goes up, the cost to hedge or protect against that associated disruption also increases, we will circle back and talk about that a little bit later.
