Abstract: A continuous data protection system, and associated method, for point-in-time data recovery. The system includes a consistency group of data volumes. A support processor manages a journal of changes to the set of volumes and stores meta-data for the volumes. A storage processor processes write requests by: determining if the write request is for a data volume in the consistency group; notifying the support processor of the write request including providing data volume meta-data; and storing modifications to the data volume in a journal. The support processor receives a data restoration request including identification of the consistency group and a time for data restoration. The support processor uses the data volume meta-data to reconstruct a logical block map of the data volume at the requested time and directs the storage processor to make a copy of the data volume and map changed blocks from the journal into the copy.
