The 1.1 manual of VDR states "Do not use Data Recovery with vCenter Servers running in linked mode".
If this only means that we need to vSphere Client login to each vCenter server and use the VDR that way, that would not be a big deal. If it means that it will cause failure of vCenter in linked mode, well that's a problem.
Mammer; can you give any more details of your enviornment?
