Disaster Recovery

Plans and procedures for restoring IT infrastructure, systems, and data after a catastrophic event -- whether a cyberattack, natural disaster, hardware failure, or human error.

Understanding Disaster Recovery

Disaster Recovery (DR) focuses on the technical restoration of IT systems and data after a disruptive event. A DR plan defines Recovery Time Objectives (RTO -- how quickly systems must be restored) and Recovery Point Objectives (RPO -- how much data loss is acceptable), documents the procedures for restoring each critical system, identifies required resources and personnel, and establishes testing schedules to validate the plan works.

Modern DR strategies leverage cloud-based replication, automated failover, and immutable backup architectures. The 3-2-1 backup rule (three copies of data, on two different media types, with one copy off-site) remains the foundation, but ransomware has driven adoption of immutable backups that cannot be modified or deleted, even with administrator credentials.

DR and Ransomware

Ransomware has become the primary driver of DR planning. Modern ransomware specifically targets backup systems, attempting to encrypt or delete them before encrypting production data. Effective DR for ransomware requires immutable backups, air-gapped or isolated backup copies, regular backup testing and restoration drills, and backup monitoring to detect encryption or deletion attempts. Without verified, protected backups, organizations face the choice of paying the ransom or rebuilding from scratch.

DR for San Diego Businesses

San Diego organizations face DR requirements from multiple compliance frameworks. HIPAA requires contingency planning and data backup procedures. SOC 2 evaluates backup and recovery as part of availability criteria. PCI-DSS requires tested recovery procedures for cardholder data systems. Beyond compliance, San Diego’s risk profile -- including earthquake, wildfire, and the growing cyber threat landscape -- makes robust DR planning essential for business survival.
