  We have seen something similar happen in a couple instances with 3.4. What we 
have found is that if _anyone_ who has administrative authority starts up the 
Java GUI the first time, it comes up in "Configure NetBackup" mode. If, by 
mistake, you don't exit fairly quickly, and happen to start in on the 
configuration of your already configured system, it can wipe out major portions 
of your configuration.

  We have not had the desire to test this extensively with our operational 
systems. So we don't know exactly at which point in the sequence things start 
getting over-written. Someone else can do so if they desire. ;)
