Once you have determined a Disaster Recovery strategy it's time to do some work in your primary IT environment with two very important objectives in mind. The first is to improve the resiliency of your systems (prevention is better than cure) and the second is to ensure that when it's time to recover you have everything you need to successfully recover.

Disaster Recovery is more than writing some recovery procedures and performing a DR test twice a year - Disaster Recovery has to be integrated into the very DNA of an organisation to be truly effective. This includes ensuring that Disaster Recovery is an integrated part of your change control procedures, having effective Disaster Recovery policies, ensuring your IT architects build DR into all they do, and having regular high level reviews of your Disaster Recovery strategies.
