When I first began researching modules I looked at this one but decided to use the default backup tool... which, by the way, constantly timed out once my site filled out a bit. Since I'm using virtual shared hosting, I really didn't have much recourse but to use phpAdmin to backup my database. But with the extra steps, I didn't backup as much as I should have. Finally I decided backups are too important to "forget" so I got this modules and I've never regretted it. Now I do my backups see more quickly with a click of the mouse-button. And recently I used it to roll back after my site got messed up with too many code changes... the process was easy and stress-free.
