Oracle Database 12c: Advanced Administration — Question 12

Which two statements are true about RMAN duplexed backups?

Answer options

• A. It is only supported for backups to tape via media management interface.
• B. It is not supported for image copies.
• C. For performing duplexed backups, the parallelism for the device must be set equal to the number of copies.
• D. Duplex backups can be performed on either disk or media, but cannot be performed on media and disk simultaneously.
• E. Duplex backups can contain only data files and control files.

Correct answer: D, E

Explanation

Option D is correct because duplex backups can be executed on either disk or media but cannot be done on both at the same time. Option E is also correct, as duplex backups are limited to containing only data files and control files. The other options are incorrect as they either misstate capabilities or requirements of RMAN duplexed backups.
