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.
