                       chmod +x /tmp/*.sh          
                       echo "Executing restore script"        
                       ls -lh /work-dir/backup         
                       bash /tmp/restore.sh $BACKUP_ARG $BACKUP_FILE     
                       sleep 15m

2. Execute the below command to run the restore job:

   kubectl create -f ocnadd_restore.yaml 

3. Restart the ocnaddconfiguration, ocnaddalarm, and ocnaddhealthmonitoring pods once the restore job gets completed.

Note:

If the backup is not available for the mentioned date, the pod will be in an error state, notifying the Backup is not available for the given date: $DATE, in such case provide the correct backup dates and repeat the procedure.
