Database Management
The following procedure shows the commands used to back up the contents of the system configuration data-
base (located on flash) to a secure TFTP server.

1.9.1.3 Specifying Source for a Database Backup
In normal system operation, all persistent data attributes are stored in RAM memory on the CFC and dynami-
cally written to the system database in the onboard FLASH. However, in abnormal failure cases the data integ-
rity of the database in the onboard flash can become suspect, due to alarm conditions including flash memory
failure or software audit failure. In these failure cases, any attempt to backup the database would fail since the
onboard flash is not reliable as a backup source.
When the onboard FLASH database integrity is suspect due to flash memory failure, the user has the option to
create a binary database file based on the RAM memory contents, since in this case the RAM data is usually
still reliable as a backup source.
If the SOURCE parameter is not specified, the default behavior is the same as in previous releases, with the
source for the database backup being the onboard flash database.
The backup operation will still fail if a database audit alarm is present, since in this case the reliability of both the
RAM and flash memory is questionable. However, in the case where flash failure is detected and an alarm is
raised, the database audit is suspended to prevent it from raising an additional alarm.
1.9.1.4 Database Purge
The PURGE DATABASE command erases the current configuration database. This command would be used if
the user wanted to reconfigure the system back to factory defaults. When the command is entered, the system
reboots and recovers with the factory defaults.
