As many in the IT industry are getting ready for VMworld, my mind always wanders back to what seems to be the perennial question – “Use a separate backup solution for protecting VMs … or a single solution for physical and virtual servers?”
It used to be that the Virtualization-specific solutions did an inarguably better job than the Unified players did, because they had done the extra effort to make up for insufficient backup APIs in the hypervisor(s). But those days are over. VMware vStorage APIs for data protection (VADP) and Microsoft Hyper-V’s Volume Shadow Copy Services (VSS) mechanisms ensure that every backup solution that wants to do a good job of protecting VMs can. That is NOT to say that all VM backup solutions are equal!! What it does mean is that “can I back up a VM?” is no longer the right question.
