Testing Your DR Plan: Best Practices for 2025
What would happen if your core systems went down right now?
Would your business recover in minutes, hours, or would it grind to a halt for days?
For many organizations, disaster recovery (DR) plans exist only as documents tucked away in compliance binders. But in 2025, when cyberattacks are more disruptive than ever, hybrid IT environments are the norm, and customer expectations demand zero downtime, a DR plan that isn’t tested might as well not exist at all.
For CIOs, CISOs, CTOs, and IT leaders, the real question isn’t “Do we have a DR plan?” It’s “Will it actually work when we need it most?
With the evolving cyber threats, the best practices for DR testing have evolved to meet the demands of hybrid infrastructure, cloud-first strategies, and increasingly sophisticated cyber threats.
Here’s what every IT leader should keep in mind while testing their DR plans.
1. Shift from Annual Testing to Continuous Validation
Traditional once-a-year DR drills don’t align with today’s dynamic infrastructure. With hybrid environments, SaaS adoption, and rapidly changing workloads, continuous or quarterly testing ensures that recovery strategies remain aligned with current systems, workloads, and compliance requirements.
Pro Tip: Automate test cycles where possible using orchestration tools. This not only saves time but also ensures that every system dependency is validated.
2. Include Cyber Resilience Scenarios
In 2025, cyberattacks, especially ransomware, remain the top cause of downtime. Testing your DR plan must include scenarios where:
- Data is encrypted or corrupted.
- Critical systems are taken offline by malicious actors.
- Cloud backups are targeted.
Best Practice: Test your ability to isolate, recover, and validate clean copies of data without reintroducing malware into the production environment.
3. Validate Recovery Objectives in Real Time
Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs) often look good on paper but fail under pressure. Conduct live failover tests to ensure your recovery objectives match business expectations.
Key Action for CIOs/CTOs: Align DR testing outcomes with business-critical applications. If an ERP system takes hours longer to recover than planned, reconfigure priorities before an actual outage exposes the gap.
4. Expand DR Testing Beyond IT
True resilience requires organization-wide participation. Involve business unit leaders, application owners, and security managers during DR testing to ensure workflows, communication protocols, and compliance requirements are addressed.
Example: Test how customer service teams will handle queries if CRM downtime extends beyond the RTO.
5. Test Across Multi-Cloud and Hybrid Environments
With most enterprises now leveraging a multi-cloud or hybrid IT strategy, DR testing must include:
- Cross-cloud recovery scenarios.
- Cloud-to-on-premise failover.
- Verification of data sovereignty and compliance when workloads move between regions.
Best Practice: Ensure that cloud providers’ SLAs and recovery guarantees align with your DR testing outcomes.
6. Simulate Extreme “Black Swan” Events
Testing only predictable scenarios isn’t enough. Include high-impact, low-probability events like:
- Complete regional cloud provider outage.
- Supply chain disruption affecting IT operations.
- Simultaneous cyberattack during natural disaster.
Such simulations push IT and security leaders to rethink redundancy, vendor diversity, and business continuity communication channels.
7. Measure, Report, and Iterate
A DR test is only successful if its outcomes are measurable and actionable. CIOs and IT managers should document:
- Systems that failed to meet recovery objectives.
- Gaps in team coordination or communication.
- Compliance risks discovered during testing.
Action Point: Treat each test as a feedback loop—update DR playbooks, refine response protocols, and re-train staff accordingly.
In 2025, disaster recovery testing is no longer about a checkbox exercise—it’s about ensuring true operational resilience. CIOs, CISOs, CTOs, and IT leaders must adopt continuous, cyber-aware, and business-aligned testing practices to protect their organizations from unexpected disruptions.
A DR plan is only as strong as the last time it was tested. Is your organization confident in its recovery strategy?
