Short description of 12Ghosts Backup 9.70: Keeps every change of your documents, while you are working on them, at a save place or on a different disk. Automatically stores changed versions in an archive folder and applies a smart filter to keep versions of all ages. This stores more document versions in a more intelligent way than any other backup program. Simple to use interface: just add items to a list of files or folders (supports wildcards and subfolders, e.g. C:My Documents*.doc)
