Virtualization & Disaster Recovery in Hyper-V

Hyper-V is one of the features that is available in Windows Server 2008, Windows Server 2008 R2, Windows Server 2012 and Windows Server 2012 R2. Hyper-V offers native hypervisor the ability to run virtual machines on the Intel x86-64 platform.

Virtualization & Disaster Recovery

There are various options available to protect virtual machines that run on Hyper-V as far as virtualization and disaster recovery is concerned. To run Hyper-V, there are basically two options available. It could either run as a role on one of the Windows Server releases above or as a free version of Windows Server (known as Hyper-V Server) that offers only limited functionality. Microsoft has improved or added, with each new release of Windows, the general and data protection features in Hyper-V. Many new and apt functions of Hyper-V are supported under the centralized management tool, SCVMM (Microsoft System Center Virtual Machine Manager), currently at release 2012 R2. Some of them include:

· Hyper- V Backup

Backup of Hyper-V guests is managed through The use of VSS (Volume Shadow Copy Services) is what allows Hyper-V to manage the backup of guests. Hyper-V VSS writer has the ability to suspend I/O on the hypervisor. It also has the ability to suspend I/O in the guest by using Integration Services. VSS writer does that when the snapshot and backup of the VM is taken. Currently there are numerous backup systems available that can easily integrate with VM and VSS. They include the capability to restore application data from inside the VM itself. Microsoft provides Windows Server Backup as a free tool for recovery and backup services, as a substitute to using an independent software supplier backup product.

· Hyper-V VM Replication

Microsoft introduced Hyper-V Replica, in Windows Server 2012, which is basically an IP based replication feature that permits a virtual machine image to be replicated secondary location. The replica copy can be run on the disaster recovery location, in case of failure at primary site.

With the release of Windows Server 2012 R2, the abilities of Hyper-V Replica were extended to support replication to a third site. These sites are known as the extended replica. The secondary and tertiary sites continue, in case of loss of primary site, to copy between each other and continue to maintain protection for the application.

· Hyper-V Cloud Replication & Backup

A very effective substitute to utilizing a secondary datacenter is to push VMs into the public cloud. Microsoft operates its Azure cloud and offers facilities to move VMs to and from an on premise Hyper-V deployment using Azure Site Recovery.

All in all, you can see that Hyper-V has all the tools needed to ensure that never have to suffer from data loss. But still situations may arise where these tools are not adequate enough. To guarantee that your data remains 100% sure, you can try CloudBacko, the best cloud backup software available on the web. You can use CloudBacko for smooth hyper-v backup every time.
