RPO and RTO Explained with Real Disaster Recovery Example from BlackBox Hosting
What Happened — In a Help Net Security video, BlackBox Hosting CEO Matthew Burden walks through a live disaster‑recovery (DR) scenario involving 1,200+ virtual machines. The customer contract required a one‑second Recovery Point Objective (RPO) and a four‑hour Recovery Time Objective (RTO). Data is continuously replicated between two data‑center sites, standby hardware is kept ready, and quarterly DR drills consistently restore the environment in about 90 minutes.
Why It Matters for Trust & Control Assurance
- Demonstrates the need for continuous monitoring of DR controls and documented evidence that RPO/RTO targets are met – a core control‑area for business‑continuity assurance.
- Quarterly testing provides a defensible audit trail that maps directly to the Business Continuity Management objective in the Verisq Common Framework (VCF) and aligns with NIST CSF 2.0’s “Recover” function.
- Shows how a Control‑Mapping capability can automatically collect and correlate DR test results with framework requirements, simplifying audit readiness.
Who Is Affected – Cloud‑hosting providers, SaaS operators, and any organization that relies on virtualized workloads for critical services.
Recommended Actions
- Define RPO/RTO per application based on business impact analysis.
- Implement automated replication and standby hardware as shown.
- Schedule quarterly DR drills and capture test results as evidence for control‑mapping tools.

Technical Notes – The example focuses on data‑replication latency, standby infrastructure, and test orchestration rather than a specific vulnerability or attack vector.
