    Backup configurations represent data protection strategies, recovery procedures,

    business continuity, data loss prevention, and regulatory compliance requirements.

    Backup configurations include:
    - Scheduled backup jobs and frequency settings
    - Data retention policies and archival rules
    - Recovery point objectives (RPO) and recovery time objectives (RTO)
    - Storage location and encryption configurations
    - Disaster recovery procedures and failover strategies
