Jon — Are flushed DLEs flushed alphabetically? What if some OTHER DLE’s happen to be left on the holding disk too? In my case, my backup server *might* happen to alphabetically trump all my other nodes, but that’s only a help if things ARE done alphabetically.
Are re yesterday’s vs today’s: I’m worried about catastrophe. One day won’t worry me then.
