Oracle Database Administration from Zero to Hero - Practice - Automating RMAN Backup Jobs (Part 1 of 2)

The video tutorial covers implementing a database backup strategy using Cronman. It details the backup schedule, including incremental backups and retention policies. The tutorial discusses estimating RTO and RBO, configuring backup settings, and creating scripts for execution. It emphasizes the importance of testing and verifying backups to ensure successful recovery.

What is the primary goal of implementing a database backup strategy?

• To increase database performance

• To ensure data recovery in case of failure

• To reduce storage costs

• To enhance data security

How often is an incremental backup level one taken on weekdays?

• Once at 1:00 PM

• Twice at 10:00 AM and 4:00 PM

• Twice at 1:00 PM and 8:00 PM

• Once at 10:00 PM

What does the recovery window of eight days imply?

• The system is checked every eight days

• Backups are taken every eight days

• Data can be recovered up to eight days after an issue

• Backups are retained for eight days

Which factor does NOT affect the estimation of RTO?

• Database size

• Backup frequency

• Storage bandwidth

• Recovery scenario

What is the estimated RBO if a failure occurs at 12:50 PM?

• 12 hours

• 24 hours

• 8 hours

• 17 hours

What is the purpose of configuring the retention policy to 8 days?

• To ensure backups are taken every 8 days

• To retain backups for 8 weeks

• To delete backups older than 8 days

• To create backups every 8 hours

What is the significance of the auto backup format being set to percent F?

• It defines the naming convention for backup files

• It determines the storage location

• It sets the backup file size

• It specifies the frequency of backups

Why is it recommended to save the DBID value in the backup destination?

• To enhance security

• For use in recovery scenarios

• To reduce backup time

• For auditing purposes

What should be done if an error is found in the backup log file?

• Ignore it and proceed

• Re-run the backup script

• Delete the log file

• Fix the error and try the script again

What is a recommended practice for managing backup log files?

• Delete them after each backup

• Send them to your email automatically

• Store them in a separate directory

• Ignore them unless an error occurs
