A natural disaster or significant IT outage increases executive awareness and internal pressure to create a DRP. However, using traditional methods of creating DRPs can result in lengthy, impractical plans that won't be effective during an emergency.
A common misconception regarding DRPs is that they are only necessary when significant disasters occur. Subscribing to this belief leaves the organization vulnerable to all sorts of emergencies. For example, common incidents like power outages or data loss can often have more lasting effects than large disasters, which require much more investment.
The fundamental purpose of disaster recovery is to ensure service continuity. That's why it's essential to create a plan that can be leveraged for both isolated and catastrophic events.
Your key focus should be on improving overall resiliency and recoveries rather than basing DR on risk probability analysis.
To ensure your DR is cost-effective, start with identifying what is genuinely mission-critical so you can allocate resources accordingly.
