At a certain deployment, the NetBackup 6.5 was used to back up the VCenter 4.01 virtual machine and its resident Converter plug-in. The backup process was normal. But the later restoration process failed. The error number reported by the NetBackup is 5.
Uninstall the Converter plug-in of the VCenter 4.01. Then install the VMware converter standalone 3.0.2 program.
Use the NetBackup 6.5 to restore the virtual machine again.
The NetBackup 6.5 requires the VMware converter standalone for virtual machine restoration. The resident Converter plug-in of the VCenter 4.01 cannot substitute the VMware converter standalone.
