So which volumes will it use when you want to restore from the job? The last
full and all the other incrementals etc. it used as a basis of VirtualFull? So
you actually cannot rewrite them after you've run VirtualFull from them? If it
were so, it wouldn't make any sense, would it?

So actually it IS creating a new backup, doesn't it?
PS. I would love it if you could do VirtualBase :)
