I received the following message while trying to use vcbmounter to backup a VM:
Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine.
It’s a vSphere 5.1 infrastructure but happens to be on a ESX 4.1 host. This has worked before and still works fine on other VMs. I was able to make a backup on this VM as long as it was powered off, but that’s not ideal.
The final solution for me was to make a change to the VMWare Tools. I ‘re-configured’ them and in the advanced options I set “Volume Shadow Copy Services Support” to “This feature will not be available”.
This probably isn’t the best solution, but it worked…
