Thanks for the reply! I normally don't snapshot unless I'm doing sometime to the vm. When complete, I remove them. My backup device does a snapshot but removes it promptly when completed. So the 440gb I'm showing free probably does not reflect all the provisioned space, but only the space in use at the moment? That's why I was wodering if there is a utility built into vsphere that can give you all the resource usage including provisioned space that's not in use yet.
Thanks
