US Patent 9798629 Predicting backup failures due to exceeding the backup window

Exemplary methods for predicting backup and restore failure include analyzing, at a management server, resource utilization statistics periodically collected during backup of data from a source storage system to a target storage system. In one embodiment, the methods include creating a predictive model based on the analysis of the collected resource utilization statistics. In one embodiment, the method includes predicting, using the predictive model, whether a backup time or a restore time of future backup will exceed a backup time threshold or restore time threshold, respectively.
