Critical Backup Failure: Failed to create VM snapshot at second attempt - aborting



This article explains how to troubleshoot the error message "Critical Backup Failure: Failed to create VM snapshot at second attempt - aborting" in Windows and Linux VMs.

You may receive this error message in one of two circumstances:

  • performing an agentless pairing or
  • backing up an agentless machine

More than likely the error is a result of stopped or disabled services on the virtual machine.

Steps to Resolve

To begin resolving the error, launch the VM and open the system's Services window (Start menu > type "Services"). 

  1. See if the Virtual Disk service is running. If it is running, verify that the Startup Type column reads "Automatic." If it's anything else, right-click it and select "Properties," then set the Startup Type to "Automatic."
  2. Restart  the VM once you have done this. 
  3. See if the VMware Snapshot Provider service is running. If it is and is running, right click it > "Properties" and set the Startup Type to "Disabled" and click OK. Then stop the service by clicking the "Stop" link under VMware tools.
  4. Find the VMware Tools service and restart it by clicking the "Restart" link.  

On a Linux VM

  1. Launch the Linux VM, log in as root and run the following commands to restart VMware tools:
    /etc/init.d/vmware-tools start
    /etc/init.d/vmware-tools stop
    /etc/init.d/vmware-tools restart
    /etc/init.d/vmware-tools status
