Backup Restore Capacity at 98% expected recovery team availability: a worked example

Push expected recovery team availability up to 98% and the picture changes. This example computes every intermediate figure at that operating point. Use it when testing whether recovery teams can restore critical OT systems inside the required recovery window.

The inputs for this scenario

  • OT systems restored per cycle: 5 systems / cycle (unchanged)
  • Available restore cycles: 18 cycles (unchanged)
  • Expected recovery team availability: 98 % (raised for this scenario; the documented default is 85)
  • Restore validation pass rate: 92 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross backup restore capacity = OT systems restored per cycle × available restore cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 81.14 systems for validated backup restore capacity, the number this scenario is built around.
  • At this operating point the engine returns 90 systems for gross backup restore capacity.
  • At this operating point the engine returns 1.8 systems for recovery availability loss.
  • At this operating point the engine returns 7.06 systems for restore validation loss.

How this compares with the baseline

  • Against the tool's baseline example, where expected recovery team availability sits at 85% and the headline result is 70.38 systems, this scenario comes in 15.29% above the baseline at 81.14 systems.
  • It computes validated restore capacity by multiplying systems-per-cycle by available cycles, then discounting for recovery team availability and the validation pass rate. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
