<p style={{ fontSize: '1.25rem', fontWeight: 700, marginBottom: '0.75rem' }}>Overview</p>

The nxtDR Administration Guide covers the full administrative lifecycle of NxtSight Disaster
Recovery — from initial site registration and replication topology setup through ongoing
operational management, compliance reporting, and security hardening.
