Backup and Restore from a USB key
Use a USB key to either backup a configuration file or restore a configuration file.
You should always make sure a USB key is properly install before proceeding
since the FortiGate unit must recognize that the key is installed in its USB port.

1Go to System > Maintenance > Backup and Restore.
2Select USB Disk from the backup configuration to list.
3Enter a file name for the configuration file.

Using the USB Auto-Install
The USB Auto-Install feature automatically updates the FortiGate configuration
file and image file on a system reboot. Also, this feature provides you with an
additional backup if you are unable to save your system settings before shutting
down or rebooting your FortiGate unit.
Note: To use this procedure, you must log in using the admin administrator account, or an
administrator account that has system configuration read and write privileges.
Note: You can only save VPN certificates if you encrypt the file. Make sure the
configuration encryption is enabled so you can save the VPN certificates with the
configuration file. An encrypted file is ineffective if selected for the USB Auto-Install feature.
