Oracle Database Administration from Zero to Hero - Performing RMAN Backups - Part II (2 of 3)

The video tutorial explains the use of RMAN commands for backing up archived redo logs. It covers two main commands: 'backup archive log' and 'backup plus archive log'. The tutorial details how to specify ranges for backups using SCN numbers, sequence numbers, and timestamps. It also discusses the use of the DELETE ALL INPUT option and the importance of managing disk space. The 'backup plus archive log' command is recommended for ensuring data file backups are recoverable to a consistent state.
