Works Great!
This app works great! I have three My Passport external drives and I have this app set on every 6 hours. The first drive backs up when I turn on the computer, the second 6 hours after that and the third 6 hours after the second, so each drive backs up once a day. Since my computer is on 12+ hours a day, that is great backup coverage over the whole day. Get it!!!!
