If disaster recovery isn??™t a part of your ongoing job as a
process requiring continual improvement, read this book. If you lose sleep worrying
about whether your database will fail, read this book.
How This Book Is Structured
This book is divided into three logical sections: the backup/recovery process, various
disaster mitigation techniques, and practical tips for approaching disaster recovery
within your own environment. The backup/recovery process is a necessary component
to any disaster recovery plan. Disaster mitigation techniques, such as database mirroring,
are powerful yet optional. Determining how backup/recovery and mitigation play
in to your own disaster recovery plan (and how to create that plan) means the difference
between a successful plan and losing your job.
Chapter 1 introduces my interpretation of disaster recovery. Although short, this
chapter is extremely important, because it spells out the premises I work with
throughout the rest of the book. Disaster recovery is not simply a backup/restore
process, it is not simply high-availability techniques, and it is not a project to be
completed.
