Oracle Database: RAC - OCR and OLR Backup Scripts (18c / 12c / 11g)

In this blog I present to you OCR and OLR backup scripts for RAC.
OCR and OLR backups must be maintained manually as well and if possible on a shared mount. 

There are 2 scripts below one which backs up OCR and other OLR.
The key thing common in the scripts is to define Oracle Home, Backup location and configure retention. 
If you open the script is is pretty straightforward that way. 
You can take these scripts and use it in your environment.

OCR Backup

#!/bin/bash

TIMESTAMP=`date +"%d.%m.%Y_%H:%M:%S"`
BACKUP_LOC=/data/OCR



echo "Activity time "${TIMESTAMP}

if [ -d $BACKUP_LOC ]; then

echo "Backup destination $BACKUP_LOC does exist on this server.........:"

else

mkdir -p $BACKUP_LOC

#chown -R root:root $BACKUP_LOC

#chmod 755 $BACKUP_LOC

BACKUP_LOC=$BACKUP_LOC
