Backup and Restore Data via USB Stick

The symmedia Plug&Work Box smart is equipped with a USB backup and update mechanism for network setup without a graphical interface. This requires a FAT32 formatted USB stick and a computer with (text) editor and file manager on which the settings are made. After inserting a USB stick, the symmedia Plug&Work Box smart checks whether there is a symmedia.txt file in the root directory and then executes the commands contained therein.

	NOTE!
An interruption of the power supply during a write operation can damage the device and render it unusable. - Ensure that there is a permanent power supply during backup operations.

The command structure is as follows; each string is separated by a semicolon ";":

trigger-string;sub-string1 ;sub-string2

Below are all possible commands and their functions:

trigger-string	sub-string 1	sub-string 2	Action
backup	all		Backup of the complete device.
restore	all		Restore all subsequent entries.
	network	red	Restores only the settings of the RED interface.
	network	green	Restores only the settings of the GREEN interface.

	firewall		Restores only the firewall settings.
report			Creates a complete diagnostic report.
image_update	sym-image-update.sh		Starts the script from the USB stick that is used to update the image of the box encrypted with the gpg pubkey.
