Abstract
One example method includes determining a hazard value such as a Weibull hazard function value for an operation such as a recovery operation. Enablement and disablement of a read ahead cache are performed based on the hazard value. The hazard value is representative of whether accesses to a file, such as a backup, being recovered or read are sequential or random. The read ahead cache is enabled when the accesses are sequential or sufficiently sequential.
