A system for remote mirroring of digital data from a primary network server to a remote network server includes a primary data transfer unit and a remote data transfer unit which are connectable with one another by a conventional communication link. The primary data transfer unit sends mirrored data from the primary network server over the link to the remote data transfer unit which is located a safe distance away. Each data transfer unit includes a server interface and a link interface. The server interface is viewed by the network operating system as another disk drive controller. The link interface includes four interconnected parallel processors which perform read and write processes in parallel. The link interface also includes a channel service unit which may be tailored to commercial communications links such as T1, E1, or analog telephone lines connected by modems.
