Which of the following most correctly describes simple replication?

Simple replication refers to the process where data is duplicated from one location to another, ensuring that there is a copy of the data available in multiple places. Choosing the option that describes this concept most accurately aligns with the definition of simple replication being a straightforward method for creating a backup of data. In the context of AVEVA Historian, having a duplicate storage of a tag on a second Historian means that you have an exact copy of valuable historical data that you can rely on for redundancy, disaster recovery, or load balancing.

Real-time data synchronization captures a broader process that often involves maintaining data consistency across multiple systems in real-time, which may or may not involve duplication of the same data. Data compression activities and filtered data transfer focus on manipulating data for storage efficiency or optimizing bandwidth, which do not inherently describe the concept of simply replicating data. Thus, the option that emphasizes duplicate storage specifically addresses the core idea of simple replication, making it the most accurate answer.
