Abstract
One aspect of the present invention includes enabling the efficient transfer of deduplicated data between storage pools in a storage management system without unnecessary reassembly and deduplication of data objects. In one embodiment, the storage management system tracks deduplication information for the data chunks of data objects within an index at the storage management system level, in addition to tracking storage information for each data object within another index at the storage management system level. The data chunk deduplication information is then accessible by any storage pool. Accordingly, transfers of the data objects and data chunks of the data object are easily facilitated, even between non-deduplicating and deduplicating storage pools.
