Maintaining the infrastructure for a real-time database backup involves ensuring that backups are correctly configured, continuously running, and fail-safe mechanisms are in place to prevent data loss. The most appropriate role for this responsibility is the IT database administrator (DBA) because:
* Primary Role of a DBA:
* The DBA is responsible for managing database performance, availability, backup strategies, and recovery processes.
* Ensures that real-time backups are functioning properly and failure risks are mitigated.
* Database Infrastructure & Backup Strategies:
* DBAs configure, monitor, and troubleshoot real-time backup solutions such as replication, mirroring, and log shipping.
* They work with backup tools like Oracle Data Guard, SQL Server Always On, and MySQL replication.
* Disaster Recovery & Data Integrity:
* The DBA ensures data consistency and integrity, especially during system failures or cyber incidents.
* They set up recovery point objectives (RPO) and recovery time objectives (RTO) for database resilience.
* Option B (IT Data Center Manager):
* Oversees physical and environmental infrastructure (e.g., servers, cooling, and power systems).
Not directly responsible for database backup failure prevention. (Incorrect)
* Option C (IT Help Desk Function):
* Provides user support and troubleshooting but does not manage backup infrastructure. (Incorrect)
* Option D (IT Network Administrator):
* Manages network configurations, security, and connectivity but does not handle database backup infrastructure. (Incorrect)
* IIA GTAG - "Auditing Business Continuity and Disaster Recovery": Emphasizes the role of DBAs in backup infrastructure.
* COBIT 2019 - BAI10.02 (Manage Backup and Restore): Assigns database backup management responsibilities primarily to DBAs.
* IIA's "Auditing IT Operations": Recommends that database administration teams ensure backup mechanisms are tested regularly.
