Raspbian Tools

Scripts to manage a RaspberryPi device which is running Raspbian ( These scripts have only been tested on openSUSE 12.3 distribution.


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:


Usually you would see some messages from the kernel:

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


Script that does the same things that the raspbian-chroot does but with the qemu emulation stripped out since this one is intended to run on arm systems.

Lets say you want to compile for the raspberry pi but you have a more powerful arm machine like the Odroid U3. This script will mount the raspbian image copy its contents to a separate directory and chroot to it. Copying the raspbian image content is itended to not run out of space (which happens if working directly on the rapsbian image) when compiling big projects.
