(also redundant server, server replication)
Server redundancy is a technique employing numerous servers to hold identical data and execute the same tasks, guaranteeing uninterrupted service operations in the event of a server malfunction. Server redundancy minimizes downtime risks, boosts fault tolerance, and elevates system performance through the distribution of workloads among several servers.

Server redundancy and backups serve different purposes. Redundancy aims to maintain service availability and minimize downtime, whereas backups are a means of data recovery in case of data loss or corruption. Redundant servers help prevent service disruptions, while backups restore data after a disruption has occurred.
