Abstract
One aspect of the present invention includes an optimized simultaneous storage operation for data objects onto a combination of deduplicated and non-deduplicated storage pools. In one embodiment, a data object is provided for storage onto destination storage pools in a storage management system, and placed into a source buffer. The data object is first divided into data chunks if the data object has not previously been chunked within the storage management system. The data object is then simultaneously copied from the source buffer to each destination storage pool (deduplicating and non-deduplicating) with the following operation. If the destination pool utilizes deduplication, then the individual data chunks are only transferred if copies of the individual data chunks do not already exist on the destination storage pool. If the destination pool does not utilize deduplication, then all chunks of the data object are transferred to the destination storage pool.
