Case I
Fourteen successful backups, three incomplete restorations of context
In October 2024 we examined restoration capability for fourteen instrument-system test packages. Every relevant backup job had reported success. The programme team initially proposed using that result as evidence that the recovery arrangement was ready. Laboratory colleagues asked a more useful question: could an authorised reviewer understand the restored material with the method version and associated context intact? Eleven packages met the agreed exercise criteria. Three did not supply the necessary method-version context through the restored environment. These were controlled exercises, not reports that production records had been destroyed or that medicines had been affected.
The immediate choice was between closing the exercise on the strength of the backup reports or continuing the work with a narrower account of what had been demonstrated. I recommended the latter. I asked the team to preserve the original sources and document precisely what the three exercises could not reproduce. Quality colleagues retained responsibility for assessing suitability and the further examination required. My responsibility was to provide a technical route, its dependencies and a realistic cost. We agreed a EUR1.4 million capability programme over twelve weeks, including the relevant configuration context and repeat exercises.
That programme cost more than the original completion recommendation implied, and it consumed specialist time already requested elsewhere. I took both consequences to the investment discussion. I also refused to describe the eleven passing packages as evidence about every instrument system. They established a result for those exercises and their agreed conditions. Broader coverage needed its own selection and review.
By the end of the twelve-week work, the three packages could be read with the required method context in the exercise environment, and quality colleagues reviewed that evidence. We retained the exercise record and the original limitation in the programme account. I do not present that as a universal recovery assurance or a regulatory certification. The useful change was that our readiness discussion now distinguished a completed backup job from a demonstrated ability to interpret the recovered material. That distinction has continued to shape the questions I ask before supporting a closure recommendation.
I would ask record users to define a meaningful restoration before the first backup exercise, including the context they need to interpret recovered material without reconstructing its history.
