Abstract
A host performs an optimized copy operation by reading an optimized version of data from a source data storage system, and then writing the optimized version of the data to a target data storage system. The target uses the optimized version of the data to generate a complete unoptimized copy of the data, and obtains data verification information from the source through an independent error detection communication channel that is independent from the host. The target uses the data verification information and the complete unoptimized copy of the data to perform an error detection operation that identifies any chunk within the complete unoptimized copy of the data in the target that does not match the data in the source. The target indicates the non-matching chunks to the host, and the host performs an unoptimized copy of those chunks from the source to the target to correct the error.
