Easy-to-use & straightforward interface, also creates a backup of the 1Gb hidden boot partition which it dynamically resizes. It's rather good, to be honest. I use it for an independant backup to Time Machine & excellent for disk upgrades to produce exact replica of what's installed.
A nice backup tool. Its interface is easy to work with. So you do not need a lot of time to get to know the app. I consider this to be a good advantage.
