These depend on init state 4 being [ rather a good algorithm for backups deleted] Forgive my ignorance, but I have looked through TFM, and it says that you should not do a dump on an active file system. That's OK, but WHY??? I can't see any documentation as to what would happen if you did do a dump on an live file system. My reasoning for this is that we currently do our back ups at midnight each night WITHOUT shutting down the system. Is this likely to cause problems with restoring files??
