This is wizard-driven. Very simple. You’ll need to be able to burn a CD, nothing more taxing than that.

In my last Raspberry Pi tutorial (the first in this series), I mentioned that we can take a snapshot of the Raspberry Pi’s SD card at any time. This will give us a “restore point”, so we can skip a few installation steps if we want to wipe the Pi and start again. Quite a few Raspberry Pi projects will require that we start with a working installation of Raspbian so that’s the snapshot I’m going to take. You can of course take a snapshot whenever you like. If you’ve honed and polished your Rasbmc box, it would make sense to take a snapshot in case it becomes horribly corrupted at some point or melts.

There are many different ways of skinning this cat (or squashing this ‘berry), but my preferred method is the tried and tested customised Linux distribution, Clonezilla. I’ve been using CloneZilla personally and professionally for years and persuaded many colleagues of its merits (besides the obvious, that it’s free). It can be a bit intimidating with all the options it presents. If this is your first experience of CloneZilla, following this tutorial will also give you a gentle introduction to this powerful toolkit.

What you’ll need

• A copy of Clonezilla, burned to disc.
• A computer (desktop or laptop) configured to boot from CD.
• An external hard driveImage may be NSFW.
  Clik here to view., with enough space to store the image (you’ll only need a few gigabytes spare).
• A USB reader for your SD card. You can buy one hereImage may be NSFW.

Take a snapshot

1. Power down your Pi, with the command halt, shutdown or poweroff.
2. Boot your PC from the Clonezilla disc. You will arrive at a simple menu/boot screen. It will boot automatically within 30 seconds – you can hit enter at any time, to proceed.

22. I’d recommend checking the saved image though. It doesn’t take long and gives you peace of mind that you should be able to restore from this image.

23. Clonezilla will helpfully point out that you can do all this from the command line (yeah, right).

27. Enter 0 to power off (or whatever you prefer) followed by enter.

You should now have an image (consisting of several files) on your external hard drive, which you can later use for restoration. Job done.
