Just several quick thoughts. 1) Is there any difference, and if so what, in the state of the source Mac at the times of the two backups? I.e., is it awake when you initiate the "manual" B/U (probably) and sleeping at the time of the scheduled one? Yes, SD can cope with a sleeping machine, but you might try trying to have the states identical, if you can and if they aren't now, and see what happens.

2) I suppose you have already tried erasing your schedule and redoing? If not, maybe do so. Try a scheduled B/U ten minutes after you run your manual one, have the state of the machine as it has been at night, and see what happens.

3) Do a complete erase, maybe going so far as to write zeroes, of the backup drive and then try -- as the first B/U on it afterwards -- the scheduled B/U.

These are unscientific, although I hope logical, shots in the dark. Good luck.
