to compare with vcenter, feature in EM is already present for quick backups done via "vcenter only" defined jobs. That works and wasn't the issue I am targeting.
What I am pointing out is, that somehow "vcloud" backup type was forgotten. In case the backup job is setup as vcloud (so expecting working vcloud director), quick backup option is unavailable(greyed). And I really don't know, what could be the constraint for that.
I can trigger the vcloud backup job ad-hoc via powershell, via backup console, so I think EM talking to B&R should have same options enabled, but it currently doesn't.
We are using vcloud director and we are missing such option, as our backup types are all of type "vcloud".
