Abstract
A system, method and computer program product for consolidation of incremental backups, wherein each incremental backup includes data and a backup map with links that point to data of current and/or previous backups, including selecting a plurality of incremental backups to be consolidated; combining the links in the backup maps of the selected backups into a single set of links; consolidating the selected backups to a new backup that contains the latest data from the selected backups, the latest data determined based on the links in the single set; updating the links in the single set to point to the data in the new backup; and storing the updated links 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 incremental 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 incremental backups are organized into a tree.
