In one embodiment, deduplication information for data chunks of data objects is stored at a system-wide level to enable the transfer and access of data chunks stored among multiple storage pools. When a data object is accessed on a first storage pool that contains damaged or inaccessible data chunks, the undamaged and accessible chunks may be retrieved from the first storage pool, in addition to retrieving an undamaged copy of the damaged or inaccessible data chunks from alternate data storage pools. Thus, a complete data object can be retrieved or recovered with a combination of chunks from the first storage pool and other storage pools within the storage management system, without requiring the entire data object to be retrieved from a backup source. | 03-18-2010 |
