The following describes the procedure for restoring backup data from the maintenance PC connected to the unit.
(a) Preparation
• The maintenance PC shall have the capability of executing the scp command. (Tera Term has the scp capability.)
• Stop the unit, and then connect it to the maintenance PC by using an Ethernet cable.
If necessary, disconnect other devices from the unit.
• Change the OS operation mode of the unit from normal mode to maintenance mode.
• Use terminal emulation software for remote connection to the unit from the maintenance PC, and then log in to the
unit by using SSH.
You must log in as a user who can run the sudo command.
• The time required to restore data from a backed up file is approximately 30 seconds per GB. If files are to be
verified, additional time (approximately 30 seconds) is required. More time might be required depending on the
transfer rate of the external media. In addition, the time for transferring backup files to the unit is required.
(b) Operation procedure
Use the remote operation terminal to remotely log in to the unit in which the backup data is to be restored, and then
run the restoration command. Then, send backup data from the maintenance PC to the unit by using the scp operation
terminal.
