Managing VM checkpoints
With Hyper-V in Server 2019, a checkpoint captures the state of a VM into a restore point. Hyper-V then enables you to roll back a VM to a checkpoint. Windows Server 2008's version of Hyper-V first provided this feature. With Server 2008, these restore points were called snapshots. With Server 2012, Microsoft also changed the name to checkpoint. This made the terminology consistent with System Center, and avoided confusion with respect to the Volume Shadow Copy Service (VSS) snapshots used by backup systems.
While the Hyper-V team did change the terminology, some of the cmdlet names remain unchanged. To restore a VM to a checkpoint, you use the Restore-VMSnapShot cmdlet.
When you create a checkpoint, Hyper-V temporarily pauses the VM. It then creates a new differencing disk (AVHD). Hyper-V then resumes the VM, which writes all data to the differencing disk. You can create multiple checkpoints for a VM.
Checkpoints are great for a variety of scenarios. They can be useful...
