we use VAW for physical endpoints and sometimes you have configuration issues which are due to updates or whatever. So you know that you have a existing configuration within your last backup but if you do a bare metal restore, it will need some time. From B&R I think we all know the feature "quick rollback" which uses CBT and veeam metadata to just restore the changed blocks since the choosen restore point.
I think VAW also has metadata about the blocks (but this time the physical and not the blocks provided by the hypervisor), it would only have to check the whole MFT before it will be able to restore the deltas. I think it would be a great feature - what do others think about it?
