Understanding VMware vSphere Recovery with Doyenz rCloud

In his latest post, Virtualization Expert David Davis looks at the the details behind the DRaaS offering from Doyenz. Keep an eye out for weekly posts from Davis on the Doyenz blog.

Being a techie guy, when I heard about Doyenz's new option to backup vSphere virtual machines to the cloud, my immediate question was “how does it work?” While there may be many reasons to consider DRaaS (see my post 10 Reasons to Choose DRaaS), there are also so many different forms of it that you have to really investigate exactly what a company is referring to when they say that they offer “DRaaS” or “cloud backup and recovery.”

Being a visual guy, I really love graphics that depict how something works. So when I saw this graphic from Doyenz on the vSphere backup and recovery offering, the lightbulb went off: 

How Doyenz rCloud Works

If we look at the graphic in more detail, here’s how the different pieces break down:

  • Your vSphere Infrastructure: Of course it all starts with your own vSphere infrastructure, the ESXi hosts running in your datacenter. They house your company’s most critical resources – applications and data used by end users every day.
     
  • Doyenz Agent: The new Doyenz Agent for vSphere is a virtual appliance that you download from Doyenz. While you can download it and then deploy it like other appliances, the Doyenz virtual appliance is quite unique in that you can deploy it from your web browser directly to an ESXi host without ever actually downloading it locally and then using something like the vSphere client to deploy it. This innovation makes deploying the vSphere agent faster than other comparable virtual appliances. The agent VM, now running on the host, is able to access the virtual machine disk files for the VMs you want to protect and then push them up the “the cloud”, aka the “Archived Virtual Servers” in the graphic.
     
  • Archived Virtual Servers: Your protected virtual machines are securely stored in the Doyenz cloud and are immediately ready to be used for three different purposes – disaster recovery, disaster prevention, and recovery verification (all shown in the graphic).
     
  • Disaster Recovery: The most crucial use of your archived servers is to bring up one, or multiple, virtual machines in the event of a disaster. These VMs can be recovered within 15 minutes and then reconnected back to your virtual infrastructure.
     
  • Disaster Prevention: The most frequent use of your archived servers is to bring them back up and recover individual files. These can be restored back into production in a variety of ways.
     
  • Recovery Verification: Performing a traditional DR test is a huge undertaking, but testing DR with Doyenz rCloud is easy as you can bring VMs up anytime you want, without any disruption to production. While this can be used for DR verification, it’s also an excellent way to create a temporary virtual lab that you can test performing an upgrade on or testing a configuration that you are considering putting in production.

In summary, the DRaaS service from Doyenz is easy to understand and offers a numerous benefits.
