I agree with those who say that this is primarily useful for backing up small things like system settings regularly. The biggest problem that I can see is that it won't replace an existing backup, it always makes a new folder--you either have to have a backup drive large enough to store several copies of your files and/or delete them manually. If you're backing up bookmarks, history, address book, etc. that's no problem and it probably would be a big help to have those kinds of archives someday. As it is, if I were to use this, I'd probably have to use another backup program for most of my files.

Also, the interface is confusing, in that, for example, if you choose to backup the desktop folder in the "home folder" category, but then choose specific items from the desktop to backup in the Desktop category, you get two copies of the files backed up. It would be better to see a minus sign(-) on the Desktop folder in the Home category to show you had chosen a partial backup of that folder.

The other thing I'd like to see is a "check all" button for the lists, because you're more likely to want to pick just a few large, unimportant things (like Adobe application support) in a folder to omit from the backup than to want to include just a handful of items.

All in all, a potentially valuable app, but not for me.
