(4) Backing up data in configuration No. 3
The following describes the procedure for backing up data in the external media connected to the unit.
(a) Preparation
• Create partitions in the external media, and format them with EXT4.
The backup data save area in the external media must be formatted with EXT4.
• Prepare external media that has 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. More time might be required depending on the transfer rate of the external
media.
• Change the OS operation mode of the unit from normal mode to maintenance mode.
(b) Operation procedure
Log in to the unit in which the information to be backed up is stored, and then run the backup command.
