Snapshot Schedules - Best Practice?

[cfvonner]

So I'm having issues again, but only with Windows Server 2012R2 VMs.  Apparently there are some issues with Microsoft's VSS when running on vSphere, as documented here: VMware KB: Creating a quiesced snapshot of a Windows virtual machine generates Event IDs 50, 57, 137, 140, or 12289 and here: VMware KB: Cannot take a quiesced snapshot of Windows 2008 R2 virtual machine.  They reference some technotes from Microsoft, but there is no real solution at this time.  I created a test VM with a GPT disk (per Microsoft's Auto-recovery fails on all but the first volume of an MBR disk) and tested doing vCenter Synchronization with it.  I got flooded with errors from the Nimble device that it couldn't create the snapshots.  So, for those VMs, I have disabled the synchronization on all but my daily snapshots.  There is a way to disable quiescing on a VM-by-VM basis: VMware KB: Cannot take a quiesced snapshot of Windows 2008 R2 virtual machine.  I'm going probably going to try that next.
