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. The storage arrays are replicated as a separate, storage-centric continuous process. Metadata concerning the management server, the hosts and/or the VMs is periodically captured and made accessible to a recovery site. Upon a recovery event, replication of the storage arrays is halted, and a number of target machines corresponding to the management server and the hosts to be recovered are assigned. The hosts are not previously assigned to any particular task prior to the disaster event. The assigned management server and hosts are then bare provisioned by installing operating systems or hypervisors as specified by a subset of the metadata. Only then are recovery target machines connected to the replicated storage arrays so that virtual machines can be activated. Specification of which virtual machines are to be recovered can therefore be delayed until such time as disaster occurs and the user need not specify which virtual machines are to be recovered in advance of such an event. |
