Backup and Restore Data

The symmedia Edge Devices are 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 Edge Device checks whether there is a symmedia.txt file in the root directory and then executes the commands contained therein.

An interruption of the power supply during a write operation can damage the device and render it unusable.

Please 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
