You need to treat your IT disaster recovery (DR) plan as if it was a
Disaster recovery testing is the foundation of any DR plan health regimen. The more frequently and completely you test, the more likely you'll be able to reveal those hidden gotchas that could cause a recovery to stumble. But re-examining some of the basic premises of your plan is good practice, too.
For instance, the value of certain applications and data may change over time, making the application that your initial business impact analysis (BIA) classified as "critical" not quite as important now. You should revisit your analysis results on a regular basis and see if they still stand up in the context of current business operations.
Some other crucial parts of your IT disaster recovery plan should also get a periodic checkup. A big chunk of your disaster recovery budget probably goes to maintaining a recovery site, whether it's company owned or a facility provide by a service. What was an adequate setup a year ago might strain under today's recovery load. Conversely, you may have overestimated your needs back then and current testing indicates the need for a less elaborate (and cheaper) facility.
When you engage a disaster recovery site provider, keep your contracts short or make sure there's enough wiggle room in the agreement to make adjustments -- up or down -- later. You also need to be vigilant for changes in the "patient's" constitution. Adding new technologies like data deduplication might keep your production environment slim and trim, but they can also make recoveries more complex.
We've touched on a few key points here, but a DR plan needs a lot more care and feeding to stay in shape. Read on for some great expert advice and tips to help you keep your IT disaster recovery plan healthy.
