In this video, Robert McMillen talks about how to and why to create a Hyper-V Virtual Machine checkpoint. Checkpoints give you a point in time snapshot of your VM in case it doesn’t reboot after applying updates or installing new hardware. The reason we create a checkpoint is to ensure that if we apply any updates or install HW that we can go back to our original working configuration if the VM doesn’t come back online. This adds high availability to an administrator on a reboot.
- [Voiceover] Checkpoints in virtual machines give you…a point-in-time snapshot of your virtual machine…in case it doesn't reboot after applying updates…or installing new hardware.…Many times we have to reboot our virtual machines…because we need to run Windows updates or we need to do…some other installation that requires a reboot.…But there's a risk in rebooting virtual machines,…and that is sometimes they get hung up…and won't reboot cleanly.…It'd be great if we could go back in time to when the server…was running correctly, and we can now do that.…
So, we'll start off in Hyper-V Manager,…and we'll highlight one of our virtual machines,…and we'll right-click on it, and we'll choose checkpoint.…On the right-hand side you can see that it is creating…a checkpoint, and you can see the percentage of how long…it's going to be before it gets to 100%,…and then it's all done.…At that point we can reboot our virtual machine,…and we don't have to worry as much that it won't come…back up again.…So, one of the questions would be why don't we always…
