This document contains scripts for performing nightly full backups and weekly incremental backups of an Oracle database. The nightly full backup script uses RMAN to configure control file autobackup, allocate disk channels, perform a level 0 incremental backup, backup archive logs, switch log files, and validate restores. The weekly incremental backup script recovers the database to a point in time 7 days ago, performs a level 1 incremental backup, backups archive logs, and deletes obsolete backups.
