The one file which regularly has this message is my Outlook.pst file, holding my email messages. I assume that while Outlook is open this file will not back up so I close Outlook and down every evening and restart it every morning, so Outlook is closed for over 10 hours each night.
Sometimes the file will back up in a couple of hours, but usually it does not back up, even after 10 hours. This is very frustrating.
Does anyone else have this problem, and how do I ensure that the file backs up?
I am running Windows 7 Pro, 64 bit.
