Oracle Database 12c: Advanced Administration — Question 116

Which two are true about incremental backups? (Choose two.)

Answer options

• A. A backup set can be used as the baseline for an incremental backup.
• B. Differential backups can be taken at level 0.
• C. An image copy can be used as the baseline for an incremental backup.
• D. A tablespace incremental level 1 backup always backs up all blocks in the backed up tablespace.
• E. Incremental backups are not permitted when using block change tracking.
• F. A database incremental level 0 backup always backs up all database blocks.

Correct answer: D, F

Explanation

Answer D is correct because a tablespace incremental level 1 backup does indeed back up all blocks that have changed since the last backup. Answer F is also correct as a database incremental level 0 backup will back up all database blocks. The other options either misrepresent the nature of incremental backups or present incorrect scenarios.
