While this is a nice idea, after looking at the specifications and screenshots, based on its description, it simply does not seem to cut the mustard. The reason I say that is that it does not seem to address any of the folders and files that will end up in a system library folders that support various applications for all users. For me it is this particular area that makes a backup and reinstall so difficult. I have the space to completely back up my user folder and all user folders, as well as my application folder what takes the time is finding all the support files and folders in the root library folder and preserving them. To the best of my knowledge there currently is no application available that will do this. This means that after the new system is in place, if a user does not search through the root Library folder (the library folder is on the hard drive on opening it) for support files and applications, and back them up manually, they may have to do a complete reinstall of some of their applications after reinstalling the system, in order for those applications to work properly again. What complicates this issue more is that some of the files are invisible. So what this means to the average user, is that formatting the drive and installing a new system can be a very daunting task. Based on this description with the software should be doing, is backing up all the visible and support files for applications that are not in the user folder but scattered in the various other libraries of Mac OS. Based on the specifications and screenshots, this program does not do that. It would be nice to see a future version that did this. Then it wouldn't be worth the money. For now, for me, it's just as easy in my Mac Pro, the backup my user folders and application folders to an auxiliary drive. Then I can restore those folders after installing a new system.
