• Maintain database failover, failback, restoration and recovery procedures for critical database services.
• Participate in planned database switchovers, failover tests and disaster-recovery exercises.
• Validate database availability, integrity, connectivity, scheduled processing and replication following recovery.
• Measure recovery results against approved Recovery Time Objectives and Recovery Point Objectives and recommend improvements where gaps are identified.
• Coordinate database recovery activities and dependencies with Infrastructure, Applications, Network, Backup and Cybersecurity teams.

• Apply approved database-security standards, secure configuration baselines and least-privilege access controls.
• Administer database users, roles, privileged accounts, service accounts and database-level permissions.
• Support periodic access reviews, vulnerability assessments, security patching and audit-evidence requirements.

• Develop and maintain scripts to automate routine database monitoring, maintenance, backup validation and reporting activities.
• Maintain database scripts and configuration files within approved version-control repositories.
• Monitor database platform support lifecycles and plan required patching, upgrades, migrations or retirement activities.
• Identify database technical debt and recommend appropriate upgrade, consolidation, migration or modernisation actions.

• Investigate and resolve database availability, connectivity, performance, corruption, replication and recovery incidents.
• Conduct technical root-cause analysis for significant or recurring database incidents and implement corrective actions within the assigned scope.
• Restore database services in accordance with approved operational priorities and recovery procedures.
• Prepare database health, performance, capacity, backup and recovery-readiness reports.
• Participate in on-call or emergency technical-support arrangements where required.
