Oracle Database Administration from Zero to Hero - Performing Incremental Backups (3 of 3)

The video tutorial explains Oracle's incremental backup process and introduces Block Change Tracking (BCT) to enhance backup efficiency. BCT maintains a file with changed block addresses, allowing RMAN to quickly identify changes without scanning all data blocks. The tutorial covers BCT file management, enabling and configuring BCT, and provides best practices for using incremental backups. It also includes queries to evaluate BCT effectiveness and concludes with a summary of key learning outcomes.

What is the purpose of Block Change Tracking (BCT) in Oracle?

How does RMAN utilize the BCT file during incremental backups?

What is the maximum number of incremental backups that the BCT file can hold?

What should you do after every 7 incremental backups when using BCT?

What is the recommended action if changes to the database exceed 20% of its total size?

What happens to the BCT file if BCT is disabled in a database?

Describe the difference between differential and cumulative incremental backups.
