In one example, a method includes receiving, at a physical proxy node, a backup request from a client outside the cluster environment, the backup request identifies a VM that is to be backed up, and including data that resides on a virtual federated database that is an element of the cluster environment and to which respective databases of each node of the cluster environment are mapped, and the backup request is received at the physical proxy node due to the position of the physical proxy node in a PSOL. Next, initiating, with an agent at the physical proxy node, a save program on the physical proxy node, and initiating, with the save program, a secondary save process on the physical proxy node that is a federated backup process and includes reading the VM identification from the backup request, and backing up the VM identified in the backup request.

Proxy based backup and restore of hyper-v cluster shared volumes (CSV)

In one example, a method includes obtaining cluster and machine configuration information, sending a restore request for one or more machines, and loading a backup of a virtual machine, the backup having been created by a federated backup process involving the physical proxy node, and the virtual machine includes data that resides on a virtual federated database that is an element of a cluster environment and to which respective databases of each of a plurality of nodes of the cluster environment are mapped. Next, the virtual machine is taken offline after the backup of the virtual machine has been loaded, and after the virtual machine has been taken offline, the virtual machine is removed from the node where it resides. The backup of the virtual machine is then restored, and the restored virtual machine brought online, after which the restored virtual machine is enabled as a cluster-wide virtual machine.

Proxy based backup and restore of Hyper-V cluster shared volumes (CSV)

In one example, a method for data protection in a cluster environment includes identifying data in the cluster environment that is to be backed up, where the identified data includes data that resides on a shared disk of the cluster environment. Next, a physical proxy node, from which a backup of the identified data will be performed, is selected. The selected physical proxy node is in the cluster environment. A federated backup of the identified data is then performed from the physical proxy node and generates a backup. The backup is then stored for later restoration to a node of the cluster environment.

Proxy-based backup and restore of hyper-V cluster shared volumes (CSV)

A method, system, article of manufacture, and apparatus for creating backups of workloads in a clustered environment is discussed. In some embodiments, each node in the environment may sequentially back up its active workloads. The nodes may take data snapshots of a cluster shared volume, and thereafter extract the necessary workload data. The process may be controlled from a master node or an external server.

Federated backup of cluster shared volumes

A method, system, article of manufacture, and apparatus for restoring workload backups in a clustered environment is discussed. In some embodiments, each node in the environment may be sequentially restored based on a request received from a remote client. Additionally or alternatively, the process may be controlled from an external server.
