I liked this app and found it useful, but after one upgrade (last year) I lost several years worth very important files. Fortunately, I had made backups. The MacPaw staff was very helpful and enabled me to restore the lost files; however, the memory of that experience lingers. Right now I am not using this app because I do not want to risk losing files again. I am sorry for that, because the idea is an excellent one, and I felt very secure during the initial period that the app was working well.
