vCenter backup fail

I keep running into the same issue where BE2014 will error out when it reaches vCenter in the VM backup scheme.

I get the following messages whether BE is backing up the whole datacenter or backing up the indivual VM.

vcenter test-Backup -- The job failed with the following error: An attempt to take a snapshot of a virtual machine failed because it was unable to quiesce an application. 

A quiesced snapshot could not be created for the virtual machine (DC)ha-datacenter(DC)\vm\Vcenter.

Is vCenter supported in BE2014?
