On-Premises Disaster Recovery
On-Premises Disaster Recovery (DR) is a strategy for protecting and restoring IT infrastructure and data that is hosted locally within an organization's own physical facilities, rather than in the cloud. It involves implementing backup systems, redundant hardware, and recovery procedures to ensure business continuity in the event of disasters like hardware failures, natural disasters, or cyberattacks. This approach gives organizations direct control over their recovery assets and data sovereignty.
Developers should learn and use On-Premises Disaster Recovery when working in environments with strict data privacy regulations (e.g., healthcare, finance), legacy systems that cannot be migrated to the cloud, or where low-latency recovery is critical. It is essential for ensuring high availability and minimizing downtime in scenarios where cloud-based DR might not be feasible due to compliance, cost, or technical constraints.
