The term virtualized server recovery (VSR) has been floating around for awhile now, but it might not be clear to some techies exactly what it means. So in this blog post I will explain some of the concepts VSR is based on and give a few examples of use cases.
Virtualized server recovery means that you recover your servers using a cloud-based disaster recovery solution. Your servers can be physical or virtual and still be recovered with VSR. It depends on a set of tools to manage the environment, and those tools are part of the provider offering.
So how does it all work? The servers that are protected by VSR service need to be replicated to the cloud with special replication software that is installed on the server. This replication software will initially replicate the data on the servers to the VSR cloud provider. The initial replication might take some time depending on the connectivity with the provider, but subsequent changes should take less time. Once the provider has the servers’ images on the cloud, recovery can be started.
There is usually a different set of options for the recovery based on the recovery objectives of the client. For example:
• Always on virtual machine (VM): In this case the VM is always available for use, whether for a disaster situation, development and testing or any other scenario.
• VM only available for disaster recovery or test: This is more straightforward; the VM is only started when you declare a disaster or want to do a disaster recovery test.
So what are the benefits of using this type of recovery? You get:
• Fully managed service, which means your IT staff can stop worrying about disaster recovery (DR) and use their valuable time serving your business instead
• Predictable costs, so you know how much your DR will cost you beforehand
• Fast deployment of your DR solution
Virtualized server recovery can be used to convert your physical servers into virtual servers and can give you the resources to test your applications in a virtual environment.
