Well, lets face it, there's been pretty much nothing in terms of decent backup solutions for Mac without having to dig in your pockets. Even Apple (at the time this is written) only offer the "Backup" application if you sign up to their .mac account.
Now we love Apple, and the Mac, but we feel that in today's climate of mass media and reducing paper systems, a backup application should be almost standard with every OS. It's true, Apple's OS X does have some very good file manipulation software 'under the hood', but still, its very difficult to access for non-UNIX savy users.
So that is more...
