OS Backup of EXADATA System
Creating a Snapshot-Based Backup of Oracle Linux Database Server with Uncustomized Partitions
http://docs.oracle.com/cd/E80920_01/DBMMN/maintaining-exadata-database-servers.htm#DBMMN21377
We do Exadata patching regularly and one of the best practice is that we should always take successful root and /u01 file system backup before any patching.
In case if the patching fails and we are unable to rollback or recover the node back to its previous position in that case these backups will helps in restoring them back to its original state.
Steps:
mkdir -p /root/tar
mount -t nfs -o rw,intr,soft,proto=tcp,nolock 192.168.1.1:/export/Prod-IB-2/backup2/DB_Server_OSBackup/ /root/tar
