Final summary

Your disaster recovery plan will be truly tested only at a very difficult time for your business--during a disaster. Careful planning and thorough testing may mean the difference between a temporary inconvenience and going out of business.

The goal of your disaster recovery plan is to get your CICS® systems back online. The currency of the data and the time it takes to get back online is a function of which disaster recovery tier you use. Unless legal requirements for disaster recovery dictate the type of disaster recovery you must have, the choice of tiers is usually a business decision.

Making your disaster recovery work requires a good plan, up-to-date documentation, and regular testing.
