US Patent 11068357 Uninterrupted restore operation using a time based approach

An apparatus for performing restore operations for data packets by a restore agent is provided. The apparatus predicts a first time period of completing a first restore operation for the data packets and determines a second time period of performing the first restore operation until the first restore operation is stopped at a point of time. The apparatus also identifies an incomplete status of the first restore operation at the point of time based on a comparison between the first time period and the second time period, and collects information describing the incomplete status. The apparatus further starts a second restore operation for the data packets from the incomplete status based on the information.
