Organizations tailor disaster recovery plan structure and content based on their size, technology footprint and risk environment.
What types of disasters or disruptions should be addressed in the plan?
A disaster recovery plan should take into account hazards that pose the greatest risk based on an organization’s unique circumstances and vulnerabilities. Some potential disruptions that are typically considered include:
- Natural disasters (floods, fires, storms)
- IT outages and systems failures
- Cyber attacks like malware, hacking or denial of service
- Human errors and accidents
- Equipment damage or faults
- Building issues and utility outages
- Workplace violence or civil disturbances
- Supply chain disruptions
- Public health emergencies or pandemics
The plan aims to establish procedures to address all plausible emergency scenarios an organization could encounter given its location, industry and business model.
What information should be backed up and secured as part of disaster recovery preparations?
Vital information that should be regularly backed up and protected includes:
- Databases and digital archives
- Network configurations and system settings
- Software, applications and security tools
- Contracts, legal documents and licenses
- Business data and analytics
- Email communications
- Product designs and intellectual property
- Human resources records
