(2) Restoring data in configuration No. 1
The following describes the procedure for restoring backup data from the external media connected to the unit.
(a) Preparation
• Stop the unit, and then connect it with 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 device.
(b) Operation procedure
Use the maintenance PC to remotely log in to the unit in which the backup data is to be restored, and then run the
restoration command.
