A-to-Zerto Glossary of Terms
Organizations depend on IT infrastructure, applications, and data being constantly available. When a disaster causes extensive IT downtime and data loss, the combined costs can put a organization out of business, make critical public services unavailable, and even threaten national security. Disaster Recovery —from strategy, planning to testing and execution— aims to mitigate and manage downtime and data loss.
What Is Disaster Recovery (DR) ?
Disasters that cause IT downtime and data loss range in size and event type, but they all threaten your organization’s ability to do business.
In IT, disaster recovery (DR) is a combination of plans, procedures, and data protection and recovery solutions that can bring your IT services and data back online as quickly as possible with minimal data loss from a disruptive event. DR for many organizations is a requirement for service-level agreements (SLAs) or industry regulations.
Without a DR solution and plan in place, organizations can face downtime and data loss measured in days. With an effective plan and solution in place, a prepared organization can recover within minutes with near-zero data loss.
DR can not only help you react to unplanned events (natural disasters, infrastructure failures, power outages, user errors, corruptions, etc.), but also help you protect your data during planned disruptive events (migrations, cloud adoption, datacenter consolidations, etc.).
Key Considerations of Disaster Recovery
When creating your DR strategy, you should consider several key points to help your organization be prepared when disaster strikes.
- Recovery time objectives (RTOs) and recovery point objectives (RPOs). The two most important factors in DR are getting operations back online as quickly as possible (RTO) and preventing data lost (RPO).
- Ransomware resilience. One of the most prominent human-made disasters causing disruptions is ransomware. Your DR strategy should make protection from ransomware a priority.
- Workload prioritization. Analyze your data to identify which systems, applications, and data need the highest levels of data protection and availability and which might require less.
- Total cost of ownership. Look beyond the purchasing cost or licensing cost. The total cost of ownership will include implementation costs, management costs, training costs, and the costs of recovery.
- Replication technologies. Your strategy’s replication technologies should be virtualized and cloud compatible.
- Disaster recovery as a service (DRaaS). If your organization doesn’t have a suitable site or expertise for DR, consider DRaaS as a solution.
