Claim 11:
12. The system of claim 8 wherein the backup chain comprises a plurality of incremental backup images of the source volume,
wherein the plurality of incremental backup images are associated with a respective plurality of snapshots of the source volume taken at different times, each snapshot having a bitmap embedded, and
wherein each bitmap of a respective snapshot identifies data from the source volume that was to be copied to secondary storage for creation of a respective incremental backup image, and the process further carries out the steps of:
merging each of the plurality of incremental backup images into the full backup image to create a second synthetic full backup image of the source volume;
receiving a request to regenerate the backup chain comprising the plurality of incremental backup images;
retrieving a respective bitmap from the respective snapshot;
copying from the respective snapshot the data backed up from the source volume and identified by the respective bitmap to a respective regenerated incremental backup image; and
repeating the retrieving a respective bitmap and the copying from the respective snapshot until each of the plurality of incremental backup images of the source volume have been regenerated, thereby regenerating the backup chain.
