Abstract
A system and method for verifying the consistency of mirrored data sets is provided. A verification module executed on a destination storage system transmits a list of desired persistent consistency point images (PCPIs) to a source destination storage system. The source destination storage system identifies a common subset of PCPIs and returns a list of the common subset to the destination. The destination initiates a separate connection for each PCPI in the common subset. The source then generates a data stream which is transmitted to the destination for use in verifying the PCPIs.
