You'll need to look at the PostgreSQL logs to see what they say.
But I'm curious about the 7za step. It gives no errors or warnings?
IIRC, you need to use VSS on Windows to avoid sharing violations when
opening the files unless a specific open mode is used. It could be that
7za uses that by default, but it's also possible tha tit's not actually
backing up all files...
