VMware Cloud Disaster Recovery FAQ

General

What is the VMware Cloud Disaster Recovery service?

It is a VMware delivered cloud service that protects on-premises vSphere workloads to VMware Cloud on AWS. It replicates VMs to cloud efficient object storage, and when a disaster event occurs, it recovers those VMs on VMware Cloud on AWS. Built for IT infrastructure professionals responsible for IT services and its availability, it provides highly reliable, low TCO, easy to use disaster recovery with fast recovery capabilities.

What regions is the service available in?

The service is currently available in the following regions: Sydney, Singapore, Canada (Central), London, Frankfurt, US East (N. Virginia), US East (Ohio), US West (N. California), US West (Oregon).

Requirements and Compatibility

What protection configurations are supported?

VMware Cloud Disaster Recovery can protect workloads running in an on-premises data center to a VMware Cloud on AWS SDDC.  

What versions of vCenter and vSphere are required at the on-premises datacenter to support VMware Cloud Disaster Recovery?

See the VMware Product Interoperability Matrices for details

What is the minimum host requirement for the pilot light SDDC option?

The minimum requirement for a pilot light is currently 3 hosts. The on-demand option has no minimum host requirement and has a higher RPO. For more details see the VMware Cloud Disaster Recovery documentation

Do customers need VMware Site Recovery to use VMware Cloud Disaster Recovery?

No, customers do not need to enable VMware Site Recovery to activate or use VMware Cloud Disaster Recovery.

Can VMware Cloud Disaster Recovery be used with VMware Site Recovery?

Yes, once the recovery SDDC is created with VMware Cloud Disaster Recovery, the VMware Site Recovery add-on can be enabled on the same SDDC. This SDDC can be used as the target for both VMware Cloud Disaster Recovery and VMware Site Recovery.

Do customers need Site Recovery Manager (SRM) or vSphere Replication (VR) in their on-premises site to protect VMs using VMware Cloud Disaster Recovery?

No, customers do not need to deploy Site Recovery Manager (SRM) or vSphere Replication (VR) in their on-prem protected site to use VMware Cloud Disaster Recovery.

What do customers need to deploy on their on-prem site?

One or more DRaaS connector VMs are deployed into the on-prem vCenter to connect to the VMware Cloud Disaster Recovery components.

What are the requirements for having VMware Cloud Disaster Recovery change VM IP addresses as part of failover?

VMware Tools must be installed on the VM. For additional details see the VMware Cloud Disaster Recovery documentation.

Key Features

How many VMs can VMware Cloud Disaster Recovery protect/recover to a VMware Cloud on AWS SDDC?

VMware Cloud Disaster Recovery can support a maximum of 1500 VMs per SDDC

How would a customer protect more than 1500 VMs?

A customer can add additional SDDCs if they need to protect more than 1500 VMs

Can customers run non-disruptive DR testing similar to SRM?

Yes, non-disruptive DR testing is supported

Is it possible to failover from an earlier point in time snapshot?

Yes, the recovery runs from the most recent point-in-time by default, and others can be selected when the failover plan is run.

What is the lowest RPO supported by VMware Cloud Disaster Recovery?

VMware Cloud Disaster Recovery supports RPOs as low as 4 hours

Does VMware Cloud Disaster Recovery require a VMware Cloud on AWS SDDC in steady-state, i.e. outside of a disaster or testing?

Customers do not need a VMware Cloud on AWS SDDC in a steady-state. However, a running pilot light SDDC would avoid additional time needed to deploy an SDDC at the time of an outage.

Can a customer use an existing VMware Cloud on AWS SDDC as a failover site?

No, the SDDC must be created through VMware Cloud Disaster Recovery.

Can a customer protect some VMs with Site Recovery Manager or VMware Site Recovery and others with VMware Cloud Disaster Recovery?

Yes, as long as the same VMs are not protected by two different solutions at the same time.

Does VMware Cloud Disaster Recovery provide application-consistent or crash-consistent recovery?

VMware Cloud Disaster Recovery provides crash-consistent recovery

Does VMware Cloud Disaster Recovery require that the protected site and recovery site networks be the same?

No. VMware Cloud Disaster Recovery can change the IP address and port group of virtual machines at the time of recovery to the configuration the user specifies during setup.

Does VMware Cloud Disaster Recovery support VMs using raw device mapping (RDM) disks?

VMware Cloud Disaster Recovery supports protecting VMs with virtual mode RDMs only. Physical mode RDMs are not supported.

Does VMware Cloud Disaster Recovery update DNS at the recovery site?

VMware Cloud Disaster Recovery can update the IP address and virtual switch for recovered virtual machines but does not update DNS tables at the recovery site. However, both Windows and Linux have dynamic DNS options that can do this.

During failover, are VMs shut down and started serially or in parallel?

Virtual machines are shut down in the reverse order that they are powered on in. The user can specify the order in which virtual machines must be started.

How much overhead does VMware Cloud Disaster Recovery place on each protected VM?

VMware Cloud Disaster Recovery does not run any components in the virtual machine or on the vSphere ESX® server during normal operation, so it does not affect the performance of virtual machines.

How much bandwidth is required between the protected site and VMware Cloud on AWS?

Bandwidth requirements depend on the amount of data being replicated and the frequency of snapshots.

When a VM is recovered, does VMware Cloud Disaster Recovery verify that the VMs have booted successfully in VMware Cloud on AWS?

Yes. VMware Cloud Disaster Recovery monitors whether VMware Tools has started running in each virtual machine to determine whether the virtual machines have booted successfully.

Does VMtools need to be installed on protected VMs?

Having VMtools installed on VMs recovered by VMware Cloud Disaster Recovery is not required, though it is helpful. VMware Cloud Disaster Recovery will use VMtools for a few things related to recovery:

- VMtools will be used to shut down VMs gracefully as opposed to powering them off

- VMtools heartbeats will be used to let VMware Cloud Disaster Recovery know that a VM is ready and to start the next VM or step in the recovery plan

- VMtools are used to customize IP addresses when supported by the VM OS

What are the ports used by VMware Cloud Disaster Recovery?

See the documentation for the DRaaS connector for details
