Abstract
A system for consolidation of backups. Each backup includes data and a map with offsets or addresses that point to data of current and/or previous backups. Backup are selected for consolidation. The offsets in the maps of the selected backups are combined into a single set of offsets; consolidating the selected backups to a new backup that contains the latest data from the selected backups, determined based on the offsets in the single set. The offsets in the single set are updated to point to the data in the new backup. The updated offsets are stored 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. Offsets from the maps of first backup of the selected sequence of backups up to the last created backup are checked.
