Database: Replication vs Backup!

Replication is not a backup. Real-time replicas ensure high availability by taking over instantly when a primary database crashes.
However, replication also mirrors mistakes. An accidental DELETE command propagates to every replica instantly. True data protection requires isolated, offline backups stored separately from live systems to restore lost data.
Replication protects uptime; backups protect data integrity.
