What is the difference between high availability and disaster recovery in SQL Server?
SQL Server high availability (HA) is about providing service availability and 100% uptime through redundant and fault-tolerant components at the same location. Disaster Recovery (DR) is about providing service continuity and minimizing downtime through redundant & independent site in a distinct location.
What is DR drill in SQL Server?
