Find the disaster recovery information that you need

One of my first tasks when I was hired ten years ago was to investigate the creation of a disaster recovery site for our mainframe computer systems. I had already had some experiences with disasters and recovery. Here are some examples of a few that we included in our plans.Major Earthquake - Those of us who live in California understand earthquakes. I’ve personally been through at least five significant quakes (6.8 or greater) without suffering any damage at all. In many people’s mind, a major earthquake is the disaster scenario.One day the “big one” will come (in California) and who knows what will happen at that time. In fact, my boss and I were able to convince the CEO of our company to create a “hot site” (a duplicate site which is already ready to take over in the event of a disaster) because of a recent significant earthquake.One of the first things that we did is contact Caltech (the experts on earthquakes) to commission a study to determine where we should place our disaster site.
Reading this article about disaster recovery is not guarantee you’ll become an expert, but it’s definitely a good start.
The primary criteria was that the site be relatively close (within 50 miles) but on a different geologic plate so the earthquake would not flatten both locations.As we studied the possibility of this disaster, we realized that the building and computers might emerge from the earthquake entirely intact, but the infrastructure (power, phone lines and so forth) might be destroyed. In addition, a major earthquake is a unique disaster because it’s more likely that your people will be in complete shock and more interested in their families and homes than in restoring your computer operations.The thing to do here is be sure you’ve got the infrastructure issues covered cold. This includes phones, power and the network. Make sure you have a disaster site (or very good backups kept off-site) ready to go. Rehearse your disaster plan, and make sure your people know what to do.Minor Earthquake - A minor earthquake might be easy to survive (we’ve been through several of them with no issues) and it might introduce some interesting quirks on it’s own. The power might be out, phone lines might be down and take weeks to repair, and the general infrastructure (roads, food shipments and so on) might be disabled.
In addition, earthquakes tend to put people into a state of shock, so it might be difficult to get people to recover and get back to work.Biological Event - When envelops fill of anthrax started appearing on the news, we were suddenly confronted with a new type of disaster. What if a biological attack or event occurred in our building? What if the receptionist opened an envelop contaminated with anthrax? We would then be confronted with a unique situation. The building would be sealed and off-limited for days, weeks or even months; and we would not be allowed back in under any conditions for any reason for that time.This situation is probably one of the worst disaster scenarios of all.
This article on disaster recovery manages to be both informative and humorous.
The old building and equipment is intact but completely unreachable. Tantalizing and frustrating. Sigh. What to do?Hope and pray that you’ve got an excellent disaster recovery plan and a very competent team, that’s what you do. In this case, you’d better have a hot site or, at the very least some excellent backups.

There are two things certain in this world, death and taxes. After reading this article about disaster recovery you may discover another certainty: It doesn’t hurt to be well-informed about things you never really considered interesting before.
