No, that is not possible today. Can you explain me how you would see this because on the reasons we think this is not a good option is that we would need to keep the "shutdown" process alive for a longer period. If you are at the end of the day, and you want to go home with your laptop... Would you want to wait for x minutes until that backup finishes before you actually can?
To give you an example what I do... I backup my machine at 23.00. Which is in normal circumstances the time I am not working anymore. After that I finished the backup, I let it shut down the PC automatically. Is that an option for you? (or similar of course....)
Let us know
