Abstract
A computer-implemented method for migrating an object from a deduplication store to an external domain in an external media is described. A deduplication store (dstore) deduplication map (dmap) is retrieved from a dstore for an object stored in the dstore. A determination is made as to whether an external dmap exists in the external domain for an object referenced in the dstore dmap. If the external dmap exists, a determination is made as to whether data referenced in the dstore dmap exist in the external dmap. If the referenced data do not exist, the referenced data is extracted from the dstore to the external domain. If the external dmap does not exist, the object and the associated dmap are extracted from the dstore to the external domain.
