i have the same problem on my (single) Hyper-V Host. Everytime i got a Error "Backup performance data collection failure".
Backup performance data collection failure
Fired by event: VeeamBpPerfCollectionFailedEvent
Event description: Failed to collect performance data for object IPxxx.xxx.xxx.xxx . Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
Initiated by: Veeam ONE Monitor
I changed the credentials, checked if Remote Registry and WMI is running, but still no luck.
I found a older article, http://www.veeam.com/kb1914
, but i think that is not the correct solution ?
