Some of the administration information that is entered using the Network Computer Administration forms is not automatically saved as part of the Netra j Save and Restore feature. The relevant system files must be saved manually if you intend to restore these settings after a system crash. The entire directory /var/dhcp should be saved to an off-line storage medium such as magnetic tape or diskette. It is recommended that the contents of this directory be backed up at regular intervals, particularly when new NC's have been added, deleted or modified using the Netra j user interface. These files must be restored separately in addition to the default restore procedures required during a crash recovery of a Netra j server.
