This is a simple product that works as designed. It produces fast, reliable backups, and is easy to use. Comes with a free DOS version, which is also terrific. The tech support for all TerabyteUnlimited products is the best I have experienced in my 30 years working with computers. Friendly, helpful, efficient, no attitude; and free updates for years. Highly recommended.
