Running crashplan (headless) on a Raspberry pi 2
In my grand scheme of “abuse all the low-power computing things!”, I’ve moved my crashplan backups over to the Raspberry Pi 2 (rpi2 for short). Installation is relatively painless: download the installer from the crashplan site, and unpack and execute. I installed mine under /opt/crashplan.
Afterwards, there are some things to fix, though, as by default Crashplan is only supported on the Intel architecture:
Install a working JRE (& dependencies for the GUI app should you want to launch it through X forwarding):
apt-get install oracle-java8-jdk libswt-gtk-3-jni libswt-cairo-gtk-3-jni
rm /opt/crashplan/jre; ln -s /usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt/jre/ /opt/crashplan/jre
rm /opt/crashplan/lib/swt.jar; ln -s /usr/share/java/swt.jar /opt/crashplan/lib/swt.jar
Replace some libraries by their recompiled variants - you can compile them yourself (thanks to Jon Rogers for the instructions) or download them straight from his site if you’re lazy.
wget http://www.jonrogers.co.uk/wp-content/uploads/2012/05/libmd5.so -O /opt/crashplan/libmd5.so
wget http://www.jonrogers.co.uk/wp-content/uploads/2012/05/libjtux.so -O /opt/crashplan/libjtux.so
Add a library to the CrashplanEngine startup classpath:
sed -i 's|FULL_CP="|FULL_CP="/usr/share/java/jna.jar:|' /opt/crashplan/bin/CrashPlanEngine
And now you should be able to start your engine(s)!
/opt/crashplan/bin/CrashPlanEngine start
And the desktop app (which you can forward to your local Linux pc via ssh -X user@rpi2)
/opt/crashplan/bin/CrashPlanDesktop`
this does take forever to start. But it works. Or you can use these instructions (from Crashplan Support) to administer it remotely.
