Abstract
A system, method and computer program product for consolidation of backups, wherein each backup includes data and a backup map with offsets that point to data of current and/or previous backups, including selecting a plurality of backups to be consolidated; combining the offsets in the backup maps of the selected backups into a single set of offsets; consolidating the selected backups to a new backup that contains the latest data from the selected backups, the latest data determined based on the offsets in the single set; updating the offsets in the single set to point to the data in the new backup; and storing the updated offsets in the new backup as part of a backup map of the new backup. The selected backups comprise one initial full backup and at least one backup. In the combining step, the addresses from the backup maps of first backup of the selected sequence of backups up to the last created backup is checked. The selected backups are organized into a tree.
