vmdk space for vmware esx server
I am currently trying to estimate how big of a nas I need for my backups. I need to know lets say a virtual machine on vmware esx is provisioned for 500gb but is only using 100gb, is the vmdk file for that 100gb or 500gb?

The space that will taken up by the b/u will also depend on the b/u solution. If it has de-dup, space can be less. It's really hard to determine the exact space to allocate. You'll hear b/u vendors suggest to just allocate as much space as the VM itself takes up, plus around 20% for growth. The only way to be sure is to do a test b/u with the b/u solution of your choosing. You can then 'guesstimate' appx how much space each b/u will take. You'll also need to consider incrementals.
