Defining Disaster Recovery
Working as a consultant, one of the most difficult situations to handle is restoring life to
a downed SQL Server. It??™s a stressful situation for everyone involved. When clients call
me, it means they have a significant issue. Usually they??™re unclear as to what the exact
problem is or how to proceed.
There are five words that I never want to ask but sometimes have to: ???When was your
last backup???? From the answer, I can immediately determine if this client has a clear
understanding of disaster recovery. Some immediately spring into action, pulling backup
tapes out to begin their own documented restore process. But all too often, the question
is met with silence and blank stares.
