Abstract: Techniques are disclosed for providing backup protection. A first subnet is established for replication in a first cluster that includes a plurality of host devices. Each of the host devices includes a respective controller virtual machine, which together form a virtual local area network for replication. Each of the controller virtual machines is assigned an Ethernet interface. A replication Internet Protocol address is assigned to each of the Ethernet interfaces of the controller virtual machines. Route tables and firewall rules of the controller virtual machines are modified to allow communications between nodes of the first subnet. The first subnet is configured with information related to a second subnet for replication in a second cluster. A dedicated communication channel is generated for replication between the first cluster and the second cluster based on the configuring.

Abstract: A first server in, for example, a primary datacenter, may be paired with a second server in, for example, a backup datacenter. The first server may include a first datastore, which includes a plurality of virtual machines, and the second server may include a second datastore. The first and second datastores may then be mapped to each other. The plurality of virtual machines included in the first datastore are then, without any user prompting, replicated at the second datastore. Therefore, when the first server becomes unavailable, the virtual machines included in the first datastore may still be accessible at the second server.
