I wanted to put this in a new thread, because it's more of an apology to ShirtPocket than it is a continuation of an old thread. I've been under the assumption that SD's latest update had rendered my scheduled backups inoperative. Then I noticed that sometimes they did work. Why? Reason is, MacOS has a problem when waking from sleep via Schedule (in Energy Saver), IF it went to sleep automatically. If you put it to sleep manually, all is well. Rather than duplicate the details, go to this post on Apple's forums to see more if you like.

Sorry I ragged on you a little S.P. You're OK again.
