Disaster Recovery
What is disaster recovery?
Disaster recovery is a comprehensive strategy aimed at restoring IT systems, data, and operations following a disruptive event. It involves planning, processes, and technologies to recover critical business functions swiftly and minimise downtime. Key components include backup solutions, recovery point objectives (RPOs), recovery time objectives (RTOs), and failover mechanisms to ensure business continuity in the face of adversity.
What are the 5 steps of disaster recovery?
- Assessment and planning: Identifying potential risks, assessing their impact, and developing a comprehensive disaster recovery plan.
- Backup and Data protection: Regularly backing up critical data and systems to ensure data integrity and enable swift recovery.
- Testing and validation: Conducting regular tests and drills to validate the effectiveness of the disaster recovery plan and identify any weaknesses.
- Recovery and restoration: Implementing the disaster recovery plan to restore systems, data, and operations following a disruptive event.
- Review and Continuous improvement: Evaluating the response to the disaster, documenting lessons learned, and updating the disaster recovery plan to improve resilience for future incidents.
How does disaster recovery work?
Disaster recovery works by implementing a set of processes, technologies, and plans to ensure the rapid restoration of IT systems, data, and operations following a disruptive event. This involves risk assessment, regular backups, data replication, testing, and rapid response procedures. By minimising downtime and restoring critical functions quickly, disaster recovery safeguards organisations against the impact of disasters, ensuring resilience and continuity of operations.
