What is Obsolete Backup in RMAN? | Oracle DBA Q&A | Learnomate Technologies
In Oracle's Recovery Manager (RMAN), an obsolete backup refers to a datafile backup or archived redo log backup that is no longer needed for recovering your database. RMAN considers a backup obsolete based on factors defined in your RMAN configuration settings, such as retention policies. These policies might specify keeping a certain number of backups or backups from a specific timeframe. You can identify obsolete backups using the RMAN report obsolete command and delete them to free up storage space using the delete obsolete command.
