VMware provides a disaster recovery service that lets you protect your workloads from a disaster or disruptive event by replicating them to the cloud. You can replicate virtual machines from your vSphere-based source site to vCloud Air, and recover and use the replicated virtual machines in the cloud if the source site is unavailable.

The Disaster Recovery service is based on vSphere Replication, an extension to VMware vSphere that provides hypervisor-based virtual machine replication and recovery.

You use vSphere Replication at your source site to configure your environment and replicate virtual machines to vCloud Air. You can use vSphere Replication, the vCloud Air portal, or the vCloud Air plug-in to monitor and manage the replicated virtual machines in the cloud.

Setting up Disaster Recovery involves the following high-level tasks.

Purchase the vCloud Air Disaster Recovery service.

When you purchase the vCloud Air Disaster Recovery service, VMware sets up a Disaster Recovery virtual data center for you in vCloud Air. This is the target site for your replication.

Install vSphere Replication in your source vSphere site and configure the environment to enable connections to the cloud.

See Installing and Configuring vSphere Replication to Cloud in the vSphere Replication for Disaster Recovery to Cloud documentation for information.

Configure the connection to vCloud Air using vSphere Replication.

See Configuring the Connection to the Cloud in the vSphere Replication for Disaster Recovery to Cloud documentation for information.

Using the Disaster Recovery service involves the following high-level tasks.

Use vSphere Replication to replicate the virtual machines you want to protect.

You can replicate a single virtual machine or configure a replication task for multiple virtual machines. For each replication task, you can set a recovery point objective (RPO) to a certain time interval depending on your data protection needs. vSphere Replication applies all changes made to replication source virtual machines to their replicas on the target site at the RPO interval that you set.

See Replicating Virtual Machines to Cloud in the vSphere Replication for Disaster Recovery to Cloud documentation for information.

View and monitor the replicated virtual machines in your Disaster Recovery virtual data center in vCloud Air, using either the vCloud Air portal or the plug-in.

Test the recovery of a virtual machine, using vSphere Replication, the vCloud Air portal, or the vCloud Air plug-in.

Remove test recovery data, using vSphere Replication, the vCloud Air portal, or the vCloud Air plug-in.

Recover the virtual machines when needed, for example, if your source site becomes unavailable, using either the vCloud Air portal or the plug-in.

Remove replicated virtual machines, if disaster recovery protection is no longer needed.
