This commit contains three changes in the three files: 1. A bug in the backup process meant that anything logged after a certain point did not appear in the on-screen display of the backup log, because the logger was serialised and deserialised but display code referred to the old version. Changed so that code retrieves new object. 2. Add more information to backup log when there is a missing file. 3. Add more information to restore log when there is a missing file (and remove existing code duplication of the current message). The 'missing file' situation is one that generally shouldn't occur in normal usage, but when it does happen, it is useful to have full information about the file.
