Abstract
An enterprise disaster recovery system, including a processor for running at least one data application that reads data from at least one data disk and writes data to the at least one data disk over a period of time, a recovery test engine that (i) generates in parallel a plurality of processing stacks corresponding to a respective plurality of previous points in time, each stack operative to process a command to read data at a designated address from a designated data disk and return data at the designated address in an image of the designated data disk at the previous point in time corresponding to the stack, and (ii) that generates in parallel a plurality of logs of commands issued by the at least one data application to write data into designated addresses of designated data disks, each log corresponding to a respective previous point in time.
