Abstract
Systems and methods are disclosed for copying a data object to a target storage pool using a hybrid of storage pools, in which at least one of the storage pools is particularly efficient at identifying data that should be used for copying the data object to the target storage pool, and at least one of the storage pools is particularly efficient at retrieving the data that should be sent to the target storage pool. The system comprises a performance storage pool for storing data and having relatively high performance for retrieving stored data; a deduplicating storage pool for storing deduplicated data and storing metadata about data objects in the system and which has relatively high performance for identifying and specifying differences in a data object over time; and a controller for causing the performance storage pool to retrieve differences and provide the data to the target storage pool.
