We do use Chronosync 4 with ChronoAgent for server backuptasks. This is a thing no other utility manages at this time. We do run two Mac Servers and ChronoSync does manage to sync the two devices. If the main server fails, we can switch to our Chronosync machine very easy. This is possible with ChronoAgent. Before ChronoSync we used Dantz (now Insignia) Retrospect. Customer support for Retrospect was too bad. So we switched with no regret to ChronoSync 4: More than fair price and upgrade policy. Customer Support for ChronoSync was great so far. For the user interface, the design, and functionality I rate this product with 5 stars.
