Which is not a benefit of summarization or replication?

The correct answer identifies an option that does not typically represent a benefit of summarization or replication. While summarization and replication can indeed improve data accessibility, provide redundancy for recovery, and potentially reduce storage costs, the specific assertion that simple replication data also serves as a backup method is not entirely accurate in the context of these processes.

Replication is primarily aimed at creating copies of data for availability and performance enhancements rather than serving as a backup solution. Effective backup strategies often require more comprehensive methods that safeguard data integrity and allow for restoration in varied scenarios. Simple replication does not account for data versioning or retention that a dedicated backup system would typically provide. Therefore, while it might offer some level of availability, it does not fulfill the distinctive role and assurance that a proper backup method guarantees.

Thus, understanding the nuances between replication and backup systems clarifies why the assertion regarding replication serving as a backup method does not align with its intended benefits.
