Virtual machines can use a Cluster Shared Volume only when communication between the cluster nodes and the volume is functioning correctly, including network connectivity, access, drivers, and other factors. You probably didn’t notice any issues...

How to delegate access in Hyper-V

In some medium/large organizations, it is common practice to have different access levels for systems, such as administrator, help desk, support and auditor.

Restoring Hyper-V and Virtual Machines using Windows Server Backup

Cluster, Hyper-V Replica, Storage Migration, and other features makes for a higher availability for Hyper-V virtual machines, but it is impossible to provide 100 percent assurance in any system. When we lose a host computer, for example, not only is a single system offline, but also all the virtual machines that are running in there. It does not matter if it is only an application, a virtual machine, or the...

Backing up Hyper-V and virtual machines using Windows Server Backup

Previous versions of Hyper-V (like 2008, 2008 R2 and 2008 R2 SP1) had complications and incompatibilities with the built-in backup tool, forcing the administrators to acquire other solutions for backing up and restoring. Since Windows Server 2012, Windows Server comes with a feature known as Windows Server Backup (WSB), which has full Hyper-V integration, allowing you to back up and restore your server, applications, Hyper-V, and virtual machines. WSB is...
