Previous versions of Hyper-V had complications and incompatibilities with the built-in backup tool, thus forcing the administrators to acquire other solutions for backing up and restoring.
Windows Server 2012 onwards, Microsoft enhanced the built-in Windows Server Backup (WSB) tool. It has full Hyper-V integration, thus 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 built-in 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.
