Install Crashplan on a Raspberry Pi

Update:

Crashplan is quite difficult to install on the RPi and is not supported officially to be installed on ARM architectures. Thus, a possible workaround to backup your data on your RPi is to setup an NFS server and to backup on it. However, the set up of an NFS mounted disk as backup destination for Crashplan is not possible. The workaround is to:

• create an empty directory as the backup destination on the local disk

• create the same directory on the nfs

• setup the local directory as the backup destination on Crashplan

• remove the local directory while the Crashplan app is still opened

• soft link (ln -s) the nfs directory to the location of the previous local directory

and voilà!

Install the required packages

sudo apt-get install oracle-java8-jdk
sudo apt-get install libjna-java

Install Crashplan

Download Crashplan.

Untar the tgz file.

And run the installation script, to install Crashplan as root:

./install.sh

Crashplan will not work out of the box.

Patch Crashplan to work on the Pi

Force Crashplan to use the RPi (Raspbian) JRE:

sudo rm -r /usr/local/crashplan/jre
sudo ln -s /usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt /usr/local/crashplan/jre

And change these two files:

cd /usr/local/crashplan
sudo rm libjtux.so
sudo wget http://bougui505.github.io/assets/libjtux.so

sudo rm libmd5.so
sudo wget http://bougui505.github.io/assets/libmd5.so

Start Crashplan

$ sudo /usr/local/crashplan/bin/CrashPlanEngine start
$ sudo /usr/local/crashplan/bin/CrashPlanEngine status
CrashPlan Engine (pid 1891) is running.

Configure Crashplan remotely using the local Crashplan user interface (UI)

Definitions:

• The local computer is defined as your desktop computer
• The remote computer is the RPi

See the Crashplan support for full explanations.

Copy the token from the Rpi:

The token is located in /var/lib/crashplan/.ui_info if Crashplan is installed as root or in ~/.crashplan/.ui_info if installed as user.

The format of the .ui_info file is:

PORT,Authentication_Token,IP_Address

Copy the Authentication Token from the RPi and paste it to replace the Authentication Token in the local .ui_info file, after having backup the local .ui_info file.

Change the port in the local conf file

Just change the port from 4243 to 4200 in the local .ui_info file.

Start port forwarding on the local computer

ssh -L 4200:localhost:4243 pi@raspberrypi

And start CrashPlanDesktop on local computer…

NB: This doesn’t work anymore…
