How to list OLR backups and take a manual OLR backup in Oracle RAC

OLR is per node, so is its backup. ocrconfig -local -showbackup lists the OLR backups on the current node; -local -manualbackup cuts a fresh one.

The manual backup writes to the OLR backup location. Run as the Grid Infrastructure owner, on the node whose OLR you want backed up.

# List OLR backups on this node
$GRID_HOME/bin/ocrconfig -local -showbackup

# Take a manual OLR backup on demand
$GRID_HOME/bin/ocrconfig -local -manualbackup
