01_The_Problem
Single-node databases created downtime risk and no path to recovery under failure.
02_Architecture_Solution
Primary / replica topology with synchronous replication for durability and automated failover. Backup schedules covered point-in-time recovery, retention policies, and offsite copies. Regular DR drills validated recovery time objectives under simulated failure.
