The resource credentials used for backing up the virtual machine are not associated with the resource container (Vcenter).



1. Add the IP address of the resource container (Vcenter) being backed up if the name is used or vice versa and then run the backup of the required resource.

2. If the above step works, the original resource container can be deleted and be readded.


Note: If the resource container is deleted it will also delete the catalogs. The media will have to be cataloged again.
