    Abstract: An enterprise disaster recovery system, including at least one data disk, a processor for running at least one data application that reads data from the 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 within the period of time, each stack operative to process a command to read data at a designated address from a designated one of the at least one 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 ones of the plurality of data disks, each log corresponding to a respective previous point in time, wherein the plurality of previous points in time within the period of time are specified arbitrarily by a user of the system.

    Abstract: A system and method for verifying consistency of data in a recovery system, the method including: protecting data in the recovery system, the recovery system includes a target disk configured to store a replica of a protected storage system from before a time window and a journal including data and metadata of write operations to the protected storage system that occurred during the time window; verifying consistency of the replicated data, concurrently with the protecting by: copying data of a selected chunk of the protected storage system at a specified time point, while monitoring write operations to the protected system; generating a replica of the selected chunk in the recovery system from the target disk and the journal, from the specified time point; comparing the copied data of the selected chunk with the replica of the selected chunk and repeating the copying, generating and comparing for a plurality of chunks.

    Abstract: A system and method for generating replicas of a file of a protected storage system from protected data in a recovery system. The method including protecting data in a recovery system including a target disk configured to store a replica of the protected storage system from a before a time window and a journal including data and metadata of write operations to the protected storage system that occurred during the time window, obtaining a request to restore a file and an indication of a specified time point from which the file should be restored, generating a replica of a table of content of a file system of the protected storage system from the journal and the target disk, extracting location of the file from the table of content, and generating a replica of the file from the journal and the target disk, using the extracted file location.
