OpenWRT full backup and restore

This tutorial walks you through how to fully backup your openwrt router setup to an image file that can be restored from openwrt's CLI interface, backup configs, and uploading to ftp and external storage. You will need to install lftp for this script to work.

Openwrt reset defaults via CLI
-------------------------------------
mtd -r erase rootfs_data


OpenWRT - Show your router's mtd RAM blocks
------------------------------------------
cat /proc/mtd

Restore Image (via CLI)
--------------------------------
mtd -r write /tmp/router_backup.bin firmware


#!/bin/sh
cd /tmp

rm *.bin
dd if=/dev/mtd0 of=/tmp/uboot.bin
dd if=/dev/mtd1 of=/tmp/kernel.bin
dd if=/dev/mtd2 of=/tmp/rootfs.bin
dd if=/dev/mtd3 of=/tmp/rootfs_data.bin
dd if=/dev/mtd4 of=/tmp/art.bin
dd if=/dev/mtd5 of=/tmp/firmware.bin

#Upload
lftp -e "put -O /router/images/ /tmp/uboot.bin; bye" -u username,password ftp://my.ftpaccount.net
lftp -e "put -O /router/images/ /tmp/kernel.bin; bye" -u username,password ftp://my.ftpaccount.net
