In a single node Grid Infrastructure install (used for ASM for Single Instance DB), how do you backup the OLR ? Is there a Cluster Registry to backup ? How do you backup the ASM SPFILE (how would it be restored ?) ? Currently, we have root running "ocrconfig -local -manualbackup " to backup the OLR to an OS file.
