Fire Drills to Ensure Successful Disaster Recovery

TEST. YOUR. DISASTER. RECOVERY. PLAN.

This cannot be said enough. I have heard countless horror stories (and lived 1) of instances where backups were completing "successfully" but no one ever tested the restoration of those backups (which were, in fact, corrupt and not restore-able)- until it was too late. :/


Put in the time up front to make sure your data recovery strategy and high-availability guarantee actually "recover" and make "available" your data- the lifeblood of your organization.

It is important to remember that you can have a Secondary database server that is 100% in sync with the Primary database server, but if your application is not configured to make the switch (or your service host does not make the switch for you)- you will only have 1/2 of things recovered: the data, but not the data availability through the application.
