VDP vCenter change - Failed to initiate a backup - datastore not accessible

Hi,

i needed to deploy my vCenter from scratch. Now i'm not able to get the VDP Backups running with this new vCenter installation.

When i start a backup, it immediately returns with this error message:

"VDP: Failed to initiale a backup or restore for a virutal machine. Probable cause is the datastore for the virutal machine is not accessible."

I already googled throught the net and found some related information, that the VDP proxies are not up to date. And indeed if i do

"echo "select * from proxy_datastore_mapping" | psql mcdb -p 5555 -U admin" i get more entries than expected.

I already rebooted VDP twice, still the same error.

So, how do i get rid of the old remaining entries or is there another way to reset the VDP proxy configuration?

Thanks
