Beyond the 3-2-1 Rule- Architecting Next-Gen Backup and Disaster Recovery
In an era defined by microservices architectures, distributed edge computing, and persistent ransomware threats, the traditional "nightly backup" approach is functionally obsolete. For enterprise IT professionals, the conversation has shifted from simple data retention to resilience engineering. When milliseconds of latency impact revenue and downtime is measured in reputation rather than just dollars, legacy backup and disaster recovery (BDR) strategies fail to meet the rigorous Service Level Agreements (SLAs) required by modern infrastructure. True resilience requires a paradigm shift. It demands moving away from passive insurance policies toward active, integrated data management strategies that ensure business continuity even during catastrophic infrastructure failures. The Evolution: From Backup to Cyber Resilience For decades, the 3-2-1 rule (three copies of data, two different media, one offsite) was the gold standard. While the core principle remains valid, th...
