Abstract
Embodiments are directed to backing up a virtual machine cluster and to determining virtual machine node ownership prior to backing up a virtual machine cluster. In one scenario, a computer system determines which virtual machines nodes are part of the virtual machine cluster, determines which shared storage resources are part of the virtual machine cluster and determines which virtual machine nodes own the shared storage resources. The computer system then indicates to the virtual machine node owners that at least one specified application is to be quiesced over the nodes of the virtual machine cluster, such that a consistent, cluster-wide checkpoint can be created. The computer system further creates a cluster-wide checkpoint which includes a checkpoint for each virtual machine in the virtual machine cluster.
