Data replication for enterprise applications

摘要

Aspects of the invention provide for the selective replication of data between a secondary volume and one or more virtual volumes of a storage device. Aspects enable data to be replicated to the virtual volume(s) at one or more selectable checkpoints, and enable data stored in a secondary volume to be "rolled back" to prior secondary storage data via replication from the virtual volumes. Aspects further enable facilitating of various applications or security, among other aspects.
