Methods, systems, and computer program products for selection of a witness during virtualization system recovery after a disaster event. A recovery plan is configured to identify a witness that is then used to elect a leader to implement the recovery. Various system, and/or network, and/or component failures and/or various loss of function of components of the virtualization system can trigger initiation of the recovery plan. Based on the particular recovery plan that is invoked upon a determination of a network outage, or component failure or loss of function of a component of the virtualization system, a particular witness corresponding to a subset of entities of the particular recovery plan is selected. The witness is used to elect the leader, and the leader initiates actions of the recovery plan. The implementation of the recovery plan includes consideration of the health of components that would potentially be involved in the recovery actions.

Selecting a witness service when implementing a recovery plan

In accordance with at least some aspects of the present disclosure, an apparatus is disclosed. In some embodiments, the apparatus includes a processor and a memory. In some embodiments, the memory includes programmed instructions that, when executed by the processor, cause the apparatus to receive a snapshot of a virtual object running on a first node, determine an original configuration associated with the virtual object from the snapshot of the virtual object, determine a resource need for the virtual object from the original configuration, determine that an available resource at the recovery node is insufficient to meet the resource need of the virtual object, generate a reconfigured configuration from the original configuration based at least on the resource need, and recover the virtual object at the recovery node based on the reconfigured configuration.

System and method for reconfiguring configuration parameters of virtual objects during recovery

A system and method include migrating, by a migration controller, a first entity of a first subset of entities from a source site to a target site in a virtual computing system based on an asynchronous mode of replication. The system and method also include replicating, by the migration controller, data of a second entity of a second subset of entities from the source site to the target site based on a synchronous mode of replication in parallel with the migration of the first entity for dynamically adjusting a recovery time objective parameter.

System and method for dynamically adjusting recovery time objective in a virtual computing system

A system and method include reconfiguring original configuration parameters of virtual objects when restoring the virtual objects on a different node. Snapshots of virtual objects running on a first node can be stored on a second node. Upon failure of the first node, the virtual objects can be restored on the second node based on the snapshots. The snapshots can include configuration information of the virtual objects specifying the resource need of the virtual objects. The second node can determine whether the available resources meet the resource needs of the virtual objects being restored. If the resource needs of the virtual objects exceed the available resources, the second node can reconfigure the original configuration parameters of the virtual objects to ensure the virtual objects can be restored and run on the second node.

A system and method for protecting entities of an availability zone include creating, by a policy engine associated with a virtual computing system, a protection policy definition for replicating a first set of entities of a first availability zone of the virtual computing system to a second availability zone of the virtual computing system. Each of the first set of entities is associated with a first common tag and the first set of entities are spread across first multiple clusters of the first availability zone. The system and method further include capturing, by the policy engine, a first plurality of snapshots of each of the first set of entities in the first availability zone in accordance with a first recovery point objective parameter and storing, by the policy engine, at least one copy of the first plurality of snapshots in the second availability zone.
