Is It Time to Completely Rethink Backup Capacity Planning? Part 2
Redmond Magazine, Thursday, August 6th, 2026
Capacity estimates should evolve continuously like weather forecasts rather than remain static annual numbers.
In the second part of his series, Brien Posey extends the weather forecasting analogy to backup capacity planning.
Nobody knows exactly how much backup capacity they will need, so the task is establishing a range and making an educated guess based on probabilities that are not arbitrary.
The key point is that capacity estimates should not be static; like a forecast, they should be revised as new information arrives. Posey examines forecast confidence as a function of time, noting that near-term estimates warrant more confidence than long-range ones.
