A. Introduction
Introduction
Backup is a procedure where a copy of the
system programming data is stored on an
external storage medium, such as a floppy disk.
If it becomes necessary to re-initialize the system
programming data, it will be faster to reload from
disk than re-programming.
This section describes a backup procedure of
system programming data at on-site.
Backup Types
There are following two backup types.
1. Save (Main Unit
• Saving system programming data from the
system to the backup device at on-site can
be done during on-line mode as well as
off-line mode.
• When an attendant console is used as the
system administration device, saving the
system programming data can be done
using a personal computer with external
storage medium.
2. Load (Backup Device
• Loading system programming data from the
backup device to the system can be done
during off-line mode only.
• When an attendant console is used as the
system administration device, loading the
system programming data can be done
using a personal computer with external
storage medium.
