How did you backup production ? Through RMAN. We take daily backup to disk. Its full backup daily. is /backup a cluster filesystem or file system on one node ? /backup is mounted on SAN. Its accessible to only one node where backup script runs ( first node ) Did you check a OS log looking for any error related to file system ? Yes. We did check. There were no issues in OS log.
