System and method for generating consistent images of a set of data objects
Abstract:
A system and method efficiently generates a set of parallel persistent consistency point images (PCPIs) of volumes configured as a SVS and served by a plurality of nodes interconnected as a cluster. A volume operations daemon (VOD) executing on a node of the cluster is configured to manage generation of the volume PCPIs. Notably, the set of PCPIs is generated substantially in parallel to thereby obtain a consistent and accurate point in time reference of the entire SVS.
