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. |
