Looking back on my data center disaster recovery experiences as both an IT director and consultant, I regularly encountered organizations in various stages of defining, developing, implementing and improving their disaster recovery capabilities. Disaster recovery policies and architectures, especially in larger organizations, are complex. There are lots of moving parts: standards and procedures to be defined, people to be organized, technology functions to be coordinated and application dependencies to be identified and prioritized. Add to this mix the challenge of grappling with the inherent uncertainties (chaos) associated with a disaster – whatever the event might be – and the complex becomes even more convoluted.
It is critical to come to an agreement on some fundamental assumptions in an effort to establish and ensure both internal and external (think stakeholders and stockholders). This should be done in order to recognize the need to address these many facets of disaster recovery development. Failure to do so will only lead to significant problems down the road.
I've given many presentations that address the "DR Expec

tations Gap," in which business assumptions concerning recoverability are often misaligned with actual IT capabilities. It's a fact that without explicit assumptions being clearly identified and communicated, your disaster recovery heroes of yesterday's recovery will become tomorrow's disaster recovery scapegoats.
Key among these assumptions, of course, is establishing classes of recovery in terms of RTO and RPO, but there are also a number of fundamental considerations that need to be measured, weighed and incorporated into the disaster recovery planning process. Here are a few practical planning items whose assumptions must be stated explicitly in order to drive an effective disaster recovery design and plan:
Obviously, there are many more considerations that are critical to identify and address for successful disaster recovery, but hopefully this tip helped to point you in the right direction.
