That's the theory. But why trust a higher risk strategy, when there is a 
perfectly good tool for doing full and incremental backup that produces a 
compact and timestamped backup files as a coherent set of files in a 
backup repository? Not using it is just laziness. What happens, for 
instance, if by coincidence the database is being packed by some 
automated script at the same time as your automated backup occurs?
