Complex terminology or objectives are usually the
primary cause of misunderstanding.
??? Agreement is not a requirement for action: I??™m sure that some of you who are reading
this don??™t quite agree with how I??™ve categorized things or how I??™ve defined
disaster recovery. That doesn??™t mean the rest of the book doesn??™t have value. The
key is that you understand my position before moving forward. The same applies
to any undertaking.
??? Categorization isn??™t just show: Being a database professional, categorization is
almost a compulsive need for me, but there is a real purpose behind it. If individual
topics or problems have commonality, it is likely that approaches to discussing
them have the same commonality.
Summary
I??™ve established that disasters can be categorized in five basic ways: environmental, hardware,
media, process, and user. Each individual disaster scenario has a certain probability,
predictability, and impact, which together determine the priority of actions taken.
Disaster recovery is the process of reducing the probability or impact of a disaster and
the actions taken to respond to that event.
