How long should backup power last for a data center?

How long should one expect the backup power to last in an emergency situation?

There is an interesting paper published by Microsoft and researchers from Penn State. Lless than 5% of all outages last longer than 240 minutes, while outages of 30 minutes or less account for over 70% of occurrences. So, for the majority of events, a diesel generator is not needed and cheaper UPCs will do the job. The problem is underprovisioning based on the 70% and not being prepared for more lengthy outages. There isn’t a single figure I can give for how long backup power should last because there are many different data centers with different needs and budgets. I suggest reading the paper to gain some additional insight into how to optimize backup power infrastructure.
