Raspbian Tools

Scripts to manage a RaspberryPi device which is running Raspbian (http://www.raspbian.org). These scripts have only been tested on openSUSE 12.3 distribution.

raspbian-backup

This is a script to backup your RaspberryPi sd card from a block device. The block device is usually mounted via an SD card reader. After inserting the SD card into a reader, you can backup the entire RaspberryPi operating system by executing:

./raspbian-backup /dev/sdd .

The above command is reading the /dev/sdd block device and making a backup of it into the current directory. The script will create the backup image with a date timestamp. e.g. 2013-06-02_22h04m-raspberrypi.img

In order to know which block device was used for your card reader, you can verify by executing the command:

dmesg

Usually you would see some messages from the kernel:

raspbian-chroot

This script helps in creating a chroot environment for your RaspberryPi backup image which has Raspbian installed as the Operating System.

It requires package qemu-linux-user and kpartx (or the equivalent for your distro of choice) to be installed. To start the chrooted environment, execute it with the path to an exported Raspbian image:

./raspbian-chroot 2013-06-02_22h04m-raspberrypi.img
