This is a known issue affecting VMware vSphere ESXi 5.x and 6.0 and currently, there is no resolution.

To work around this issue perform one of the following:

  • Disable snapshot quiescing within your backup solution.
  • Do not select Quiesce guest file system when taking a snapshot of a virtual machine from the vSphere Client.
  • Downgrade the VMware Tools to previous version that is not affected.
