I have read that only for Windows VMs, VCB does a VSS level backup. The C: drive letter of VM becomes H: drive letter of the Proxy server. The only difference here is that it does not take full imge level backup of vmdk files and is supported only for Windows based VMs.
My question is: When C: of VM becomes H: of proxy server, do we still need to mount the C: on the proxy? In vmdk level backups, we need to mount the storage LUN on the proxy server i.e. the proxy server should have an equal size LUN available for VCB backup. If VM is 300 GB, we need a 300 GB LUN on proxy to take its backup? Is it the same for the VSS based Windows VM backup?
