Overview

Enterprise backup questions span strategy (3-2-1 rule, RPO/RTO), technology selection, ransomware protection (immutable backup, air gap), and operational practices (testing, monitoring).

Key Concepts

3-2-1-1-0 rule: 3 copies, 2 media types, 1 offsite, 1 immutable, 0 errors. RPO: Maximum acceptable data loss. RTO: Maximum acceptable recovery time. Immutable backup: Essential for ransomware protection.

Best Practices

Test backup recovery regularly. Implement immutable backup. Monitor backup job success rates daily. Store at least one backup copy offsite. Document and test recovery procedures.

Key Considerations

Backup is not disaster recovery. Ransomware targets backup systems. Cloud backup provides geographic diversity but has longer recovery times. Untested backups are unreliable.
