Downtime Means Real Costs
When a critical IT system goes down, the company loses money — literally, minute by minute. E-commerce system downtime means lost sales. An ERP outage halts production and logistics. Email unavailability paralyzes communication. According to industry research, the average cost of one hour of downtime for a mid-sized company is tens of thousands of dollars. For large enterprises — millions.
Business Continuity Planning (BCP) and Disaster Recovery (DR) are not "nice to have" — they are a business necessity. And with the NIS2 Directive in effect, for many companies they are also a legal obligation.
Business Impact Analysis (BIA)
The first step is understanding what is truly critical. Business Impact Analysis identifies key business processes and estimates financial, operational, and reputational losses in the event of their unavailability. It defines two key parameters:
- RTO (Recovery Time Objective) — the maximum acceptable system downtime. How long can you afford to be down?
- RPO (Recovery Point Objective) — the maximum acceptable data loss. How much data can you afford to lose? The last hour? The last day?
Based on the BIA, we prioritize systems — not everything needs to be recovered in minutes. The HR system can wait a day. The transaction system cannot.
Business Continuity Plans
A BCP is a comprehensive document describing emergency procedures for every identified scenario — from a single server failure to a natural disaster destroying the data center. For each scenario, we define: who is responsible, what steps to take, in what order, how to communicate with stakeholders, and how to return to normal operations.
A plan that is not tested is worthless. Regular tabletop exercises simulate emergency scenarios and verify that procedures work in practice. DR tests verify that backups actually work and how long it takes to restore a system from backup.
AI in Disaster Recovery
Artificial intelligence brings new value to DR on three levels. Prevention — AI monitors infrastructure in real time, detects anomalies (rising disk temperatures, unusual I/O patterns, performance degradation), and alerts before a failure occurs. Automated response — upon detecting a failure, AI automatically initiates failover procedures, redirects traffic to backup systems, and notifies the appropriate personnel. Post-mortem analysis — after an incident, AI analyzes logs and events, identifies the root cause, and recommends preventive actions.
Cloud Migration as a DR Component
Cloud computing naturally supports business continuity — geo-redundancy, automatic failover, backup to another region. But the cloud is not automatic disaster recovery. It requires deliberate design: database replication, multi-region deployment, compliance monitoring, and tested failover procedures. A hybrid cloud architecture allows keeping sensitive data on-premise while leveraging cloud flexibility for less critical workloads.
