HyperV Virtual Machine Files

[discoveranother]

Hello

 

Hyperv virtual machine as attached, accumulate rct and mrt files. I am aware that these are a new addition to Windows Sever 2016 Hyper-V, that allows the tracking of changes between backup operations. I'm concerned that they will be taking up a lot of storage space.

 

If I shutdown the VM and delete snapshots then these files disappear. I want a process whereby too many snapshots are deleted automatically without doing it manually and also to turn off automatic shapshots via powershell, as since the release 1709 a new Hyper-V feature called Automatic Checkpoints made its appearance.

 

I have tried the following in a powershell command to turn off automatice checkpoints, but doesn't seem to work, powershell doesn't recognise the AutomaticCheckpointsEnabled command:-

 

Set-VM -VMName MyVM -AutomaticCheckpointsEnabled $False or

 

Set-VM -Name MyVM -AutomaticCheckpointsEnabled 0

 

Any help appreciated.

 

Thanks all

I noticed that there are no vhdx files being saved as they should be in this screenshot attached, instead rct & mrt files are being created !!!

 

 

Thanks
