  • Hi,

    Did you try to remove it with PowerShell by using the Remove-VMSnapshot cmdlet?

    Example:

    Get-VM MyVM | Remove-VMSnapshot -Name "NameOfSnapshot"


    Best regards,

  • HI Leon, 

    Thanks for your suggestions. I tried through PowerShell cmdlet before, it doesn't work. But just now job got completed. Not sure though why it took around 6hr to delete 100GB checkpoint.

    Thanks  for your help.

  • I usually prefer PowerShell in these things, its more reliable as the GUI can get "stuck" :-)

    Glad to hear it got solved, it may indeed take a while to delete a bigger checkpoint.

  • Hi Abhishek,

    Thanks for posting in our forum!

    First, Nice to heat that we can delete the VM Snapshot successful, and the speed of snapshot deletion/consolidation purely depends on the VM type, for example high IO intensive VMs like SQL, Exchange or file servers normally takes more time to consolidate the snapshot then a normal machine, this is because during the merge, it tracks new IOs that occur in the server and must be merged. Snapshots are online without affecting the application, so this process may take longer.

    Now that we can delete the VM snapshot normally, we suggest that we observe it for a while. If next time we delete the VM snapshot and get stuck, you can continue to reply to us. We will continue to help you.

    Hope this information can help you, if you have any question, please feel free to let me know.

    Best Regards,

    Daniel
