Backup 3
Use this procedure to make a copy of your customized system data. You should
create a backup at least three times during system installation (so that
programmed information is not lost) and once after each system upgrade, service
technician visit, or major system reconfiguration.
The Inspect feature (Inspct or
) is available to view the attributes of the
backup files on the memory card prior to initiating the backup procedure. The
attributes included on the Inspect screen are the filename, the time and date of
the file creation/update, the location of the system programming port, and
information about the system software release from which the backup was made.
The list of backup files contains three manual backup filenames and two
automatic backup filenames. The factory set names of the manual backup files
are
%$&., %$&., and %$&.. When you select one of the
backup filenames, the system automatically replaces the stars in the filename with
the current month and day (
mmdd
). For example, %$&. would appear if you
selected
%$&. and performed the backup procedure on January 16. You
can rename any of the three files during the backup procedure. The automatic
backup filenames are
$872%$&. and $872%$&.You cannot change the
names of these files.
If you enter a filename that currently exists, the message
)LOHDOUHDG\H[LVWV
appears. You must enter another filename.
While the backup is in progress, you cannot access system programming
functions, your Personal Directory, or alarm clock functions (any programmed
alarms are temporarily deactivated). You may terminate the backup procedure at
any point prior to receiving confirmation of a successful backup.
If any type of programming is taking place at another extension when you begin
the backup procedure, the backup is canceled and the number of the first busy
extension appears on the screen. Attempt the backup procedure again when the
busy extension becomes idle.
If the system is turned off during a backup procedure, the backup is terminated.
The system performs a System Reset (cold start), after which you may repeat the
backup procedure.
If Home or Menu is pressed during a backup procedure, the backup is
terminated. This may result in the deletion of an old backup file. See Chapter 1,
“Programming Basics,” for details about these keys.
NOTE:NOTE:NOTE:
If the system performs a System Erase (frigid start), all programming is set
to the factory set values. If a previous backup file is available, perform a
restore. If not, the system must be reprogrammed. See “Restore” on page
3–639 for information about the system restore procedure. Also see
“Backup Messages” on page 3–637
for information about errors that may
occur during the backup procedure.
