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 entire Hyper-V host that needs to be restored. In simple words, you have to be prepared to bring your systems online as soon as possible in case of a failure.
One of the benefits of Windows Server Backup is that it is easy to use and it is present in the OS already. With a couple of clicks, your hosts and its VMs are up and running.
