RMAN Backup Script Oracle Recovery Manager (RMAN) is a comprehensive tool designed to efficiently back up and recover Oracle databases. It works closely with the server, providing block-level corruption detection during backup and restore. RMAN backups are created using the 'BACKUP' command. The primary purpose of RMAN backups is to protect your data. In the event of a media failure or disaster, you can restore your backups and recover lost changes. For more detailed information about RMAN backup concepts, you can refer to the Oracle Help Center. Additionally, if you are interested in creating an Oracle database backup using RMAN, you can find step-by-step instructions on how to do so in the Oracle-Patches website. archivelog_not_backed_up.sh cat /home/oracle/.scripts/archivelog_not_backed_up.sh
