RTMirror

Description

RTMirror lets you specify one or more folders on your local hard disk. As soon as you modify files in those folders, RTMirror will silently copy them to a different folder (either on another hard disk or on another networked computer).
RTMirror works in real time: as soon as a file is created or modified, it is automatically copied within a minute. In case of a failure of your primary hard disk, you will be able to restore your important files.
