Hurricane Katrina also point to our inability to reliably predict the scale of damage and the inability of government at all levels to cope with the aftermath of an adverse event. The adverse event can range from extreme weather conditions or disturbances in the earth's geology to human-related events caused by errors, accidents or malice.
Regardless of the cause, adverse events become disasters when the event's negative consequences affect your company's ability to maintain operations. Even though IT planners cannot predict what event may threaten the continuity of IT operations, the basics of disaster recovery planning and recovery requirements change very little. To see how your company's disaster recovery efforts may measure up, consider using the following criteria to measure your disaster recovery plan and the probability that your IT operations can be recovered to support your business operations within a short period of time.
Grade F (Unprepared)
Grade D (Marginally Prepared)

The days of having your entire backup and recovery tapes and hardware in the same building should long be a thing of the past for any of today's publicly traded companies reliant on their data systems.

It should also help to demonstrate the funding and resources needed to prevent an event from becoming a disaster by moving up one or more grades.
