US Patent 8930747 Private cloud replication and recovery

Replication and recovery for a protected private cloud infrastructure that may include hosts, virtual machines (VMs) provisioned on the hosts, storage arrays and a management server. Metadata is periodically captured and made accessible to a recovery site. Upon a recovery event, replication of storage arrays is halted, and a number of target machines corresponding to the management server and the hosts to be recovered are assigned. The assigned management server and hosts are then bare provisioned by installing operating systems or hypervisors as specified by the metadata. Only then are recovery target machines connected to the replicated storage arrays so that virtual machines can be activated.
