Abstract
A disaster recovery site storage array causes an instance of a host application or selected executables running on a host server to validate changes to an asynchronously updated replica of a storage object. Snapshots of the replica are generated before and after each set of changes to the replica are received from a remote storage array. Validation is performed by mounting snapshots to the instance of the associated host application and causing the host application instance to validate the data. If a snapshot is determined to be invalid, then the replica to recovered with the most recent known-valid snapshot. Alternatively, if each set of changes is validated prior to being applied to the replica, invalid changes are not applied to the replica. Unvalidated snapshots may be accumulated and validated independently from application of sets of changes to the replica, thereby decoupling validation from replication.
