Hyper-V checkpoint throttling

Hi,

Is it possible to throttle or limit the number of simultaneous checkpoints that can occur in a Hyper-V cluster, within Hyper-V manager or somewhere else in the Hyper-V cluster/node?

Thanks,
Hampus

    Hi HampusLind,

    Below is the experiment I did in my environment. Hyper-V's checkpoint limit is 50. When I try to create the 51st checkpoint, the following error will appear:

    In best practice, it's not recommended to create too many checkpoints for the VM, checkpoint is different from backup, if you would like to save the state of the VM, it's recommended to use the backup. When you use checkpoint to create new changes for the VM, it's recommended to merge the checkpoint in time when we think the new change is good.

    Best Regards,
    Xu Gu

    Thank you for answer Xu Gu. However, this was not my question. 50 checkpoints it the limit per VM correct? I was asking for, or trying to ask about :) if its possible to limit the number of simultaneous checkpoint operations within a Hyper-V cluster. For instance, if a backup kicks off and create a checkpoint of 200VMs at the same time it more or less slows down the Hyper-V cluster enviroment completly. I do not see a way to throttle or litmit how many checkpoints to create within the backup solution, so I was wondering if there is some cool setting in Hyper-V that can be used for this?
