Abstract: The present invention extends to methods, systems, and computer program products for creating a snapshot of a shared volume that is application consistent across various nodes of a cluster. The invention enables a snapshot of a volume to be initiated on one node which causes all applications in the cluster that use the volume to persist their data to the volume prior to the snapshot being created. Accordingly, the snapshot is application consistent to all applications in the cluster that use the volume. The invention also enables applications on various nodes to perform post snapshot processing on the created snapshot. The invention can be used in an existing backup system that is not cluster aware to enable the existing backup system to create application consistent snapshots of a volume shared by applications across multiple nodes of a cluster.

Abstract translation: 本发明扩展到用于创建共享卷的快照的方法，系统和计算机程序产品，该共享卷的应用在集群的各个节点之间一致。 本发明使得能够在一个节点上启动卷的快照，这导致使用该卷的集群中的所有应用在创建快照之前将其数据保存到卷。 因此，快照与使用该卷的集群中的所有应用程序的应用程序一致。 本发明还使得各种节点上的应用对所创建的快照执行后快照处理。 本发明可以用于不集群意识的现有备份系统，以使现有备份系统能够创建应用程序跨群集多个节点共享的卷的应用程序一致快照。
