Unable to take quiesced snapshot |VMware Communities

Hey i’m having the same problem with Server 2012 R2 backups (Veeam 9 Update 1, using VeeamZIP full method). I think the problem started around ESXi 6 Update 1 or Update 1b, I’m running ESXi 6 Update 2 now.

I have reinstalled VMWare tools (with setup /C), and upgraded to ESXI 6u2 but it didn’t help.


I get this in the vSphere client:

An error occurred while taking a snapshot: msg.snapshot.error-QUIESCINGERROR.

An error occurred while saving the snapshot: msg.snapshot.error-QUIESCINGERROR.


A timeout occurred while communicating with VMware Tools in the virtual machine.


The only error I get on the Windows guest is:

Event ID 7011 Service control manager

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the VMTools service.

No VSS or any other errors.


As of now the only fix I have is to stop the VMWare Snapshot Provider service before I run a backup.  This seems to work 100% for me.

The VMWare Snapshot Provider seems to starts and stops with the VMware tools service, it is set to manual (default setting) start but never seems to stop on it’s own.
