Scenario: A database backup in DB2 failed halfway through the process. How can the DBA ensure data consistency and integrity in this situation?
- Manually check each table for inconsistencies and correct them using SQL queries.
- Perform a full database backup again and continue with regular backup schedules.
- Restore the failed backup and apply the remaining transaction logs to bring the database to a consistent state.
- Revert to the last successful backup and apply incremental backups to reach the current state.
If a database backup fails halfway through the process, the DBA should restore the failed backup and apply the remaining transaction logs to bring the database to a consistent state. This ensures that data consistency and integrity are maintained despite the backup failure.
