A DR Site That Could Actually Be Tested

A representative engagement, drawn from the environments ITBuilders works in across the Kingdom.

The context

Business continuity has shifted from an internal risk concern to a documented regulatory expectation. Entities are increasingly required not merely to hold a recovery capability but to evidence that it has been tested and meets a stated objective. That distinction exposes a widespread condition: recovery sites that exist, are funded, report healthy, and have never been proven.

A government-sector entity held a documented disaster recovery site, a signed four-hour recovery objective, and no evidence that either was real. The site existed. Equipment was racked. Replication was configured and reporting healthy. What had never happened was a test, because testing required a production outage window nobody would authorise.

An untested recovery capability is a belief, and beliefs fail at the worst available moment.

The approach

ITBuilders assessed the recovery path rather than the infrastructure. Storage replication was functioning. Several other things were not. Network configuration at the secondary site did not match production, meaning recovered systems would have started with the wrong addressing. Certificate and identity dependencies pointed to primary-site services that would, by definition, be unavailable during a genuine failover. A licensing dependency would have blocked one application entirely. None of these were visible in any replication report.

The rebuild addressed recovery as a process rather than a facility. Network topology at the secondary site was rebuilt to mirror production, including segmentation and policy, so a recovered workload arrives in the environment it expects. Identity and certificate services were made independently available at both sites. Application dependency chains were mapped and documented, with recovery order defined accordingly — the ordering exercise alone removed two circular dependencies that would have stalled any real failover.

Recovery tiers were then set against business requirements rather than applied uniformly. A minority of systems genuinely required the four-hour objective. Most did not, and recognising that redirected budget toward the systems that mattered.

The change that made the capability real was procedural. Partial failover testing was designed to run without a production outage, on a defined schedule, with a documented success criterion for each tier. The first full test overran the stated objective. The second, after remediation of what the first exposed, did not.

What changed

The entity now holds tested evidence of its recovery capability, produced on a repeating schedule, in a form that satisfies both its internal risk committee and external regulatory review. The documented recovery objective is now a measurement rather than an assumption.

Continuity of operation

ITBuilders continues to run the test cycle, maintain the dependency map as applications change, and produce the evidence submitted at review. This is the part that decays fastest. A recovery design is accurate on the day it is documented and drifts with every application change afterwards, which is why a tested capability is an operating commitment rather than a project outcome.
