Server mirroring is a technique used for business continuity, disaster recovery and backup. Duplicating the entire contents of a server on another remote or in-house server allows data to be restored if the primary server fails.

Techopedia Explains Server Mirroring

Server mirroring is primarily implemented to create a fault tolerant and redundant server computing infrastructure. This process works through specialized backup software that is installed on the backup server and the server to be mirrored. The software routinely synchronizes and backs up data from the primary server over a secure Internet connection or VPN to the backup server. Generally, this process requires the backup server to have hardware and software configuration that’s identical to that found in the primary server.

Besides backup and disaster recovery, server mirroring is also used in load balancing by providing identical data for fast downloading to remotely connected users.
