Claim Text:
1. A method for using a reference volume for initial synchronization of a replicated volume, comprising: cloning a first new volume from a first reference volume at a primary site at a first time, wherein the first new volume and the first reference volume initially store identical content; initiating, at a second time after the first time, a replication and synchronization operation between the first reference volume on which a parent virtual machine is mounted at the primary site, and the first new volume on which a first child virtual machine is mounted at the primary site, wherein the child virtual machine and the parent virtual machine execute different instructions such that data stored on the first new volume diverges from data stored on the first reference volume after the first time; accessing a point in time snapshot of the first reference volume; coordinating with a secondary site to obtain a snapshot of a second reference volume at said point in time, wherein the second reference volume at the secondary site is an identical copy of the first reference volume at the primary site; and generating an initial backup of the first new volume at the secondary site using the point in time snapshot of the second reference volume, wherein generating an initial backup comprises: wherein the first child virtual machine and the parent virtual machine are in different replicated volume groups, wherein the different replicated volume groups each comprise a set of volumes that are replicated from a primary site to a secondary site.
