If the command terminates displaying a message other than Successfully completed, the backup
processing was interrupted due to an error. Take corrective action against the error, and then rerun the backup
command.
7. Unmount and then remove the external media from the unit.
Run the following command to unmount the external media from the unit.
$ sudo umount /mnt/ecbackup_data
8. Log out from the unit.
$ exit
To change the OS operation mode to normal mode, see 5.14.4 Changing maintenance mode to normal mode.
(3) Backing up data in configuration No. 2
The following describes the procedure for backing up data in the maintenance PC connected to the unit.
(a) Preparation
• Format the backup data save area of the maintenance PC with ext4.
• On the maintenance PC, allocate free space greater than the capacity that is actually used in the directory partitions
to be backed up.
There is no need to consider the space for unused areas in partitions because the backup file is compressed before
it is saved.
• The time required to back up data is approximately 30 seconds per GB. If files are to be verified, additional time
(approximately 30 seconds) is required. In addition, the time for transferring backup files to the maintenance PC is
required.
• 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 maintenance PC shall have the capability of executing the scp command. (Tera Term has the scp capability.)
