        Replication technology can provide high availability for Microsoft® Exchange Server data. This topic is intended to help you better understand replication storage technology, and how it is used in an Exchange Server environment.
        Replication supports high availability by having redundant data at multiple sites, but it does not prevent data corruption from occurring. If any bad data is written to the primary storage device that causes database corruption, the same bad data will be replicated to the remote sites and corrupt the remote sites' databases. Therefore, data replication does not substitute for database maintenance processes such as database backup that validates the database integrity periodically.
        In this topic, the type of data that is discussed is the data accessed by running Exchange services, for example, any write I/O request made by an Exchange process. System/OS data replication is not discussed here.
