Chapter: Security And Disaster Recovery
Backups are the foundation of business continuity and disaster recovery (BC/DR). They protect against data loss due to hardware failure, human error, malware (e.g., ransomware), software corruption, and natural disasters. However, backups alone are not sufficient—the ability to restore data accurately, quickly, and reliably is equally critical.
Without a comprehensive backup and restore strategy, organizations face high risk of data unavailability, financial loss, reputational damage, and legal noncompliance.
1. Backup Methods
Effective backup strategies involve selecting the right method based on several factors:
- Data criticality: How important is the data to operations?
- Recovery Point Objective (RPO): How much data loss is tolerable?
- Backup window: How much time is available to complete the backup?
- Storage constraints: How much space is available for backups?
- Network bandwidth: Can the network support full or incremental backups?
