VMware Quiescing Error (code 1930)

Situation

A VMware backup plan terminates with the following warning: VMware Quiescing Error. Cannot create application-consistent snapshot(s) for one or more VMs with the list of virtual machines with failed application-consistent backups.

Cause

This warning can occur for several reasons:

  • VMware Tools on guest VM are not installed
  • VMware Tools do not function properly for some reason
  • VMware Tool cannot create a snapshot

Solution

Install or Update VMware Tools

Applies to all supported Windows guest operating systems

Install or update VMware Tools to the latest version.

For Windows 2000 and later, VMware Tools installs a virtual machine upgrade helper tool. This tool restores the network configuration if you upgrade from virtual hardware version 4 to version 7 or later.

Install VMware Tools

Prerequisites:

  • Power on the virtual machine
  • Verify that the guest operating system is running
  • Determine if you have the latest version of VMware Tools by viewing the status of the virtual machine

  • In vSphere Client – Hosts and Clusters view -> right-click the Virtual Machine -> Guest OS > Install VMware Tools
  • In vSphere Web Client – Click All Actions -> Configuration -> Install/Upgrade VMware Tools
  • In vSphere Host Client - Click Actions -> Guest OS from the drop-down menu, and select Install VMware Tools
  1. Depending on Guest OS settings the installer may start automatically:
  • If autorun is enabled for the CD-ROM drive in the guest operating system, the VMware Tools installation wizard appears
  • If autorun is not enabled, launch the wizard manually:
    • Click Start > Run
    • Type D:\setup.exe where D: is your first virtual CD-ROM drive
    • Click OK
