Backup, disaster recovery, and business continuity solve related but different problems. A business needs to understand all three to prepare for disruption.
Backup creates recoverable copies
Backup protects data by creating separate copies that can be restored after deletion, corruption, ransomware, hardware failure, or other events. A backup plan defines coverage, frequency, retention, storage, isolation, access, encryption, monitoring, and testing.
Disaster recovery restores technology
Disaster recovery is the technical plan for returning servers, applications, networks, cloud systems, and data to operation. It defines architecture, restoration order, dependencies, access, alternate infrastructure, vendor contacts, and testing.
Business continuity keeps the company operating
Business continuity includes people, facilities, communications, decision-making, suppliers, customer obligations, temporary workarounds, remote operations, and manual processes. Technology recovery supports continuity, but it is not the whole plan.
RTO and RPO guide design
Recovery time objective is the target time to restore a process or system. Recovery point objective is the maximum acceptable amount of recent data loss. Leadership should define both based on operational and financial impact. Faster targets usually require more investment and testing.
Dependencies determine restoration order
An application may depend on identity, DNS, networking, storage, databases, licensing, internet, vendor services, and employee access. A recovery plan that lists only application names can miss the infrastructure required to make them function.
Testing turns assumptions into evidence
Useful tests include file restores, application restores, full system recovery, cloud data restoration, alternate connectivity, failover, tabletop exercises, and communication drills. Record results, gaps, time, decisions, and corrective actions.
People and access matter
Recovery may fail if the only administrator is unavailable, credentials are stored inside the failed environment, vendors cannot be reached, or leadership does not know who can authorize major actions. Keep secure, accessible documentation and multiple trained contacts.
Build the plan from business impact
Start with critical services and the consequences of downtime. Then define technology, people, process, and vendor requirements needed to keep those services operating or restore them in priority order.
