FolderWatch for Windows

Unlike many other backup program that will run only on demand or at defined schedule, Folder Watch guards your files all the time, without you having to lift a finger. The app does this by monitoring a given number of folders on your hard drive then polling these as long as the computer is on.

Any time a change is detected, no matter how minute, FolderWatch will automatically make a backup copy and place it in a designated folder. All of this is done seamlessly in the background while you work.
