US Patent 9971664 Disaster recovery protection based on resource consumption patterns

Assessing the need for disaster recovery (DR) protection for a virtual application may include accessing resource consumption history for constituent VMs that support the virtual application. The resource consumption history may include usage metrics corresponding to resources used by each VM. A change in a cost of downtime of the given virtual application may be produced and used to assess criteria or rules. The given virtual application may be designated for DR protection based on an assessment of the criteria. DR protection may be activated for the designated virtual applications. The DR protection may automatically expire after a period of time.
