In order to create a backup of your Hyper-V host as well as the virtual machines on it, the best option is to split the workload into two portions: the Hyper-V host backup (the physical machine), and the Hyper-V virtual machine backup (the virtual servers).

From a security point of view, a secure option that is being used for example by VPS hosting providers that we work with, is to DMZ the VMs, not the hyper-v host. By DMZ-ing the VMs instead of the host, you can access and backup the host as usual and have only the VMs exposed […]

Hyper-V in Windows Server 2008 R2 and later, around spring 2014, introduced a HyperV backup mechanism where Hyper-V creates a hidden internal checkpoint when a Hyper-V backup is initiated. Shortly after the server backup software goes into its prep phase, this checkpoint is deleted and merged automatically while the backup proceeds. See below:   If the host […]

Checkpoints (see this article for a definition) can be useful for short-term testing when you need a quick way to revert a Hyper-V virtual machine to its prior state, for example, before updating Windows or installing software. To create and delete checkpoints (aka. snapshots in older versions of Windows Server and Hyper-V), you can issue […]

If there is enough disk space to complete the operation, check the […]
