Test the backups.  Backup one file. Restore.  Backup N files.  
restore.  Backup N directories, restore.  Find a simple and 
reproducible situation which demonstrates the problem.

There is a section in the manual regarding database tables.  I 
suspect you want the File Job table, but I cannot recall from memory.

I don't know.

Someone sugested you verify your filesystem (e.g. fsck).  Have you 
done that?

I suggest avoiding trying to answer your above questions.  
Concentrate on the following.

My suggestion, as was made by others, is to find something which can 
be reproduced.  Developers cannot solve the problem if they cannot 
reproduce it.
