Backup and Recovery
Controls to support backup and disaster recovery.

BR-1: Backup |
BR-2: Recovery Testing |
BR-3: Backup Retention |
BR-1: Backup
Control Statement
Regularly backup all important data and systems, and store backups in a secure and separate location.
Control Recommendations
Use default CSP-managed backup services (e.g., AWS Backup, Azure Backup, GCP Backup and DR Service). Consider alternative backup services only when default CSP services cannot be used. Store backups and snapshots separately to primary data storage with data encrypted-at-rest.
Risk Statement
Without regular backups stored in a secure and separate location, there is an increased risk of data loss, system failures, and extended downtime in the event of accidental deletion, hardware failures, or malicious attacks.
BR-2: Recovery Testing
Control Statement
Conduct regular testing of recovery processes to ensure their effectiveness.
Control Recommendations
Ensure each test verifies the system’s ability to fully restore all data and services.
Risk Statement
Failure to regularly test recovery processes may result in ineffective response during actual incidents, increasing the risk of prolonged downtime, data loss, and compromised business continuity in the event of a disaster or system failure.
BR-3: Backup Retention
Control Statement
Prevent backups from being modified or deleted for [br-3_prm_1] day(s) or as stipulated in the agency’s data retention policies.
Control Recommendations
Use S3 Object Lock or immutable storage for Azure Blob Storage to enforce time-based retention policies.
Risk Statement
Lack of prevention measures against the modification or deletion of backups for the specified duration increases the risk of data loss, unauthorised alterations, and potential inability to recover from incidents, compromising the integrity and availability of critical information.
