Abstract
Method and apparatus for archiving de-duplicated data maintained by an intelligent backup appliance are described. In some examples, backup data managed by a backup appliance in a computer system is archived. A request to archive selected backup images of a plurality of backup images maintained by the backup appliance is received. The selected backup images are compared with a pool of de-duplicated data for the plurality of backup images maintained by the backup appliance to identify common data among the selected backup images and unique data in each of the selected backup images. A core backup is stored on first archive storage media, the core backup including at least a portion of the common data. A unique backup is stored on second archive storage media, the unique backup including the unique data a reference to the core backup stored on the first archive storage media.
