Our technique transparently tracks I/O operations of the guest to external storage and maintains a list of memory pages whose contents are duplicated on non-volatile storage. In contrast to existing methods, our technique eliminates redundant data and stores only a subset of the VM's memory pages. In this work we present a technique for fast and space-efficient checkpointing of virtual machines. With guest memory sizes of up to several gigabytes, the size of the checkpoint images becomes more and more of a concern.

Typically, a full image of the VM's memory along with processor and device states are recorded. The real extra capability with live exports comes from leveraging the live export of a checkpoint of a running virtual machine and the fact that we now have production checkpoints.Checkpointing, i.e., recording the volatile state of a virtual machine (VM) running as a guest in a virtual machine monitor (VMM) for later restoration, includes storing the memory available to the VM. The feature to live export a running virtual machine was here before and itвЂ™s still here. If you want an application consistent copy, create a production checkpoint first and export that one.

When you import that youвЂ™ll have a VM in saved state that you need to start up.

Just like you did in Windows Server 2012 R2, no change there.

When you export a running VM in Windows Server 2016 youвЂ™ll have a copy of it in saved state. The reduces the need for me to shut down a VM before I create a checkpoint to export in many cases. Well, not unless you opt to create standard checkpoints. YouвЂ™ll have to boot it up after applying the checkpoint, they do not appear running with the state at the time the snapshot was taken. That means that when we apply such checkpoints we have a consistent state just like when we restore VM from a backup. In Windows Server 2016 we now have production checkpoints. When I then export that checkpoint I donвЂ™t have to worry about the state in the VM at that point in time as it was shut down.ДЇor some workloads this isnвЂ™t a big deal bit for some this is not a great experience, hence the fact that checkpoints are вЂњвЂќnot supported in production but for test and dev. As a standard checkpoint has state in Windows Server 2012 R2 I prefer to shut down the VM, create a checkpoint and start the VM again. So why even have the option of exporting a checkpoint of a running VM? Because this enables you to have exports from various points in time, which is pretty cool and handy during test and development and trouble shooting or lab work.

WeвЂ™ve had this option since Windows 8.1 and Windows Server 2012 R2.

I noticed this because some people figured the latter was a new feature in Windows 2016. More people seem to know about the capability to export a checkpoint of a running virtual machine, not so many of the capability to export a running VM itself. The result is a VM you can import which gives you a copy of the original virtual machine in a saved state, at the point in time that you exported it. This is also possible via PowerShell so you can automate this. You just select right click in the Hyper-V manager and select Export from the context menu and follow the wizard to select an export location. A remarkably little known feature in Windows Sever 2012 R2 (and Windows 8.1) is the ability to export one or multiple running virtual machines.
