What is Data Replication? Meaning, Benefits, and Use Cases

**Data replication is the process of copying data from one or more primary sources to another location, like a central database or data warehouse. This replica helps ensure that important data is always available and can be recovered in case of emergencies. Data replication comes in various forms, including synchronous, asynchronous, transactional, snapshot, merge, key-based, peer-to-peer, change data capture, multi-master, bidirectional, and others, each designed to meet specific requirements and challenges. The benefits of data replication include a single source of truth, data availability, performance and load balancing, security and regulatory compliance, analysis and reporting, and disaster recovery. Data replication is used in various scenarios such as real-time analytics, improved performance, accessibility and availability, data warehousing, disaster recovery, and reliable data replication with tools like CData Sync.
