Abstract

A method, non-transitory computer readable medium, and apparatus that enhance management of backup data sets include receiving an operation on a region of a production data set. A corresponding region of a backup data set is marked as having a change state status until the received operation is completed on the region of the production data set and mirrored on a corresponding region of a backup data set.
