Abstract
A method to efficiently synchronize a secondary volume with a primary volume includes maintaining a primary volume on a primary storage system and creating a copy of the primary volume. Ancestry information is maintained for the primary volume and copy. The copy and associated ancestry information are physically transported from the primary storage system to a secondary storage system. The copy is loaded into a secondary volume of the secondary storage system and the ancestry information of the copy is imported into the secondary volume. The ancestry information is then analyzed to determine if the primary volume and secondary volume share common ancestry. If so, the ancestry information is analyzed to determine differences between the primary volume and the secondary volume. The secondary volume is then synchronized with the primary volume to reconcile the differences. A corresponding system and computer program product are also disclosed.
