Setting up a disaster recovery data center is, quite frankly, a task that requires meticulous planning and a good investment of time and resources. You don’t want to find yourself in the same situation again, so here are some steps and best practices to follow:
-
Establish Your Recovery Objectives: Define your Recovery Time Objective (RTO) and Recovery Point Objective (RPO). RTO is the max time your systems can be down, and RPO is the max acceptable data loss measured in time. This clarity will drive your entire strategy.
-
Choose the Right Location: Your disaster recovery data center should ideally be in a different geographical location than your primary. This reduces the risk posed by regional disasters. Distance can cause latency issues though, so balance is key.
-
Replicate Data Regularly: Implement continuous data replication to ensure your latest data is always available in your DR center. Asynchronous replication can work if you have a higher RPO, but synchronous replication offers better protection at the cost of more network bandwidth.
-
Use Cloud Services Wisely: Many companies are moving to a hybrid model, using both physical DR centers and cloud services. This provides flexibility and often lowers costs. AWS and Azure have robust DR offerings, although integration can be complex.
-
Redundant Power and Cooling: Ensure your DR data center has reliable power sources and cooling systems. This includes having backup generators and uninterruptible power supplies (UPS) for emergencies.
-
Regular Testing: Regularly test your disaster recovery plan. Actual recovery drills will highlight weaknesses and areas for improvement. Skip this step, and you might be in deep trouble when a real disaster strikes.
-
Security Measures: Implement the same security protocols for your DR center as you have for your primary. This includes firewalls, intrusion detection systems, and regular security audits.
-
Clear Roles and Responsibilities: Document roles and responsibilities clearly. Your team should know who is responsible for what during a disaster recovery scenario.
-
Backup Solutions: Don’t forget to have robust backup solutions. Tools like Disk Drill

Potential pitfalls to avoid:
- Overlooking Regulatory Requirements: Make sure your DR plan complies with industry and governmental regulations. Non-compliance can result in hefty fines.
- Not Accounting for Human Error: A solid DR plan takes human error into account. Automate processes where possible and ensure adequate training.
- Ignoring Costs: Understand the cost-benefit ratio. Sometimes, going all out isn’t necessary based on your business needs. Assess what’s critical and allocate resources accordingly.
Follow these steps carefully, and you should be able to build a resilient disaster recovery data center, minimizing downtime and data loss when disaster strikes.
