Abstract
A remote data replication facility includes a primary storage array and a backup storage array, on which tracks of data are replicated from the primary storage array to the backup storage array as they are received by the primary storage array. Remote data verification is implemented on the remote data replication facility by comparing track fingerprints, track temporal write metadata, and track spatial write metadata, for a given track on the primary storage array, with corresponding track fingerprints, track temporal write metadata, and track spatial write metadata, for the given track on the backup storage array. If any difference is determined in the combination of track fingerprints, track temporal write metadata, track spatial write metadata, for a given track, the integrity of the data at the backup storage array is not verified for the track.
