Patent ID: 8392680

Claim:
A method, comprising: exposing a set of storage volumes to a host at a requested point in time, in a virtual access mode, the set of storage volumes being handled by distributed virtual consistency groups (CGs), having a background process wherein the distributed virtual CGs update the set of storage volumes to the requested point in time; exposing a first service storage volume at a data protection appliance (DPA); determining if the virtual CGs have rolled back; and using at least one of a central manager and a splitter to account for input/output requests (IOs) when a virtual CG has not rolled back, wherein using the central manager comprises: notifying the central manager after a virtual consistency group completes a roll back or a virtual consistency group has less than a predetermined amount of data left to roll back; waiting for the virtual consistency groups to complete a roll back; and moving to a trial phase if the virtual consistency groups have completed the roll back.
