Sorry for my poor explanation, but unfortunately what Bob and you, svollrat said
have not met the content I want to know. Thus, I'll summarize my mention again.
Have you looked at Screenshot on DP 9.00 GUI.jpg I've attached at the beginning of this week?
If your answer is "yes", can you recognize the fact that the media usage shows evidently
0% graphically on it, although it had been really taken after the individual backup task finished?
In other words, is this situation good not any software bug on DP 9.00?
Regards,
Ta-chang
