Final answer:
Replication, where data is identically maintained across servers, corresponds to a mirrored configuration. This supports data redundancy and ensures high availability in case of server failures.
Step-by-step explanation:
The question pertains to the method of data backup known as replication where identical data is maintained across multiple servers. The correct answer to this question is c) Mirrored.
In a mirrored configuration, the data written to one server is simultaneously copied ('mirrored') to another server or multiple servers. This ensures that in the event of a server failure, the data remains available from another server without any loss or significant downtime. Mirroring is a common practice in ensuring data redundancy and high availability in server environments and is a cornerstone concept in disaster recovery and business continuity planning.
