Previous versions of Hyper-V had complications and incompatibilities with the built-in backup tool, forcing the administrators to acquire other solutions for backing up and restoring.
Windows Server 2012 comes with a tool 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 easy and provides for a low cost scenario for small and medium companies.
This recipe will guide you through the steps to back up your virtual machines using the Windows Server Backup tool.
Windows Server Backup does not support tapes. Make sure that you have a disk, external storage, network share, and free space to back up your virtual machines before you start.
