CrashPlan with JDK 8

[dhead666]

As part of my (slow) move to Linux I installed today CrashPlan on my RPi so my laptop could be free of it.
After a bit of googling I decided to go with Oracle’s Java 8 preview which supposed to be much faster than OpenJDK.
The following mainly based on Bion & Jon Rogers great posts.

I'm not a developer nor system admin so any suggestion is welcome.
I only tested it briefly and backed up about 100mb, but it seems very fast and stable.

Everything was compiled on the RPi against Oracle’s Java 8.


Install some dependencies
$this->bbcode_second_pass_code('', '# pacman -S cpio nss nspr ca-certificates-java libffi')

Create a temporary working folder
$this->bbcode_second_pass_code('', '# mkdir /tmp/cpins
# cd /tmp/cpins')


Install Java
Get & install java, use the latest from http://jdk8.java.net/fxarmpreview/
$this->bbcode_second_pass_code('', '# wget http://www.java.net/download/JavaFXarm/jdk-8-ea-b36e-linux-arm-hflt-29_nov_2012.tar.gz
# tar -xvf jdk-8-*.tar.gz
# mv jdk1.8.0/ /opt/jdk1.8.0/')

Temporarily add the Java binaries location for path.
$this->bbcode_second_pass_code('', '# export PATH=$PATH:/opt/jdk1.8.0/bin')
The above won't be kept during reboots, but this doesn't matter for CrashPlan as the installation script store this path in Crashplan's configs.
If you want to permanently store Java location in your path read about Environment Variables on the ArchWiki.

A fix for the missing libffi.so.5

Option 1: Just link
$this->bbcode_second_pass_code('', '# ln -s /usr/lib/libffi.so.6.0.0 /usr/lib/libffi.so.5')

Option 2: Install precompiled libffi5 package
$this->bbcode_second_pass_code('', '# wget http://dl.dropbox.com/u/6902100/archlinux/rpi-crashplan/arch_compiled/libffi5-3.0.10-1-armv6h.pkg.tar.xz
# pacman -U libffi5-*-armv6h.pkg.tar.xz')

Option 3: Build & install libffi5 package
$this->bbcode_second_pass_code('', '# wget https://aur.archlinux.org/packages/li/libffi5/libffi5.tar.gz
# tar -xzvf libffi5.tar.gz
# cd libffi5
# makepkg -A
# pacman -U libffi5-*-armv6h.pkg.tar.xz
# cd ..')

libmd5

Option 1: Download precompiled binary (by me)
$this->bbcode_second_pass_code('', '# wget http://dl.dropbox.com/u/6902100/archlinux/rpi-crashplan/arch_compiled/libmd5.so')

Option 2: Compile the binary
$this->bbcode_second_pass_code('', '# wget http://www.twmacinta.com/myjava/fast-md5-2.7.1.zip
# unzip fast-md5-2.7.1.zip
# cd fast-md5
# gcc -O3 -shared -fPIC -I. -I/opt/jdk1.8.0/include -I/opt/jdk1.8.0/include/linux \
src/lib/arch/linux_x86/MD5.c -o libmd5.so
# cp libmd5.so ../
# cd ..
')

jtux

Option 1: Download precompiled binary (by me)
$this->bbcode_second_pass_code('', '# wget http://dl.dropbox.com/u/6902100/archlinux/rpi-crashplan/arch_compiled/libjtux.so')

Option 2: Compile the binary
$this->bbcode_second_pass_code('', '# wget http://forum.excito.net/download/file.php?id=145 -O jtux.PS3-YDL6.1.patch.txt.gz
# gunzip jtux.PS3-YDL6.1.patch.txt.gz
# wget http://basepath.com/aup/jtux/jtux.tar.gz
# tar xzvf jtux.tar.gz
# cd jtux
# patch < ../jtux.PS3-YDL6.1.patch.txt')
Edit the first line in the make file so it would point to the right place.
$this->bbcode_second_pass_code('', '# nano Makefile')
$this->bbcode_second_pass_quote('', 'J')AVA_INCLUDE = /opt/jdk1.8.0/include

libjna

Option 1: Download precompiled binary (by me)
$this->bbcode_second_pass_code('', '# wget http://dl.dropbox.com/u/6902100/archlinux/rpi-crashplan/arch_compiled/jna.jar
# mkdir -p /usr/share/java
# cp jna.jar /usr/share/java/
# wget http://dl.dropbox.com/u/6902100/archlinux/rpi-crashplan/arch_compiled/libjnidispatch.so
# mkdir /usr/lib/jni
# cp libjnidispatch.so /usr/lib/jni/')

Option 2: Compile binary
Install ant which is necessary for compiling. ant got a large number of dependencies,
I highly recommend copying the list of the dependencies for later removal.
$this->bbcode_second_pass_code('', '# pacman -S apache-ant
# wget http://ftp.de.debian.org/debian/pool/main/libj/libjna-java/libjna-java_3.2.7.orig.tar.gz
# tar -xzvf libjna-java_3.2.7.orig.tar.gz
# cd libjna-java-3.2.7
# cd native
# wget https://github.com/atgreen/libffi/archive/master.zip
# unzip master.zip
# mv libffi-master libffi')

Edit the makefile
$this->bbcode_second_pass_code('', '# nano Makefile')
$this->bbcode_second_pass_quote('', 'J')AVA_INCLUDES=-I"/opt/jdk1.8.0/include" \
-I"/opt/jdk1.8.0/include/linux"

Install CrashPlan

Download & Install CrashPlan, get the latest version from CrashPlan Linux client download page.
$this->bbcode_second_pass_code('', '# wget http://download.crashplan.com/installs/linux/install/CrashPlan/CrashPlan_3.5.2_Linux.tgz
# tar -xvf CrashPlan_3.*_Linux.tgz
# cd CrashPlan-install/')

Add java 1.8 support
$this->bbcode_second_pass_code('', '# nano install.sh')
$this->bbcode_second_pass_quote('', 'O')KJAVA="1.5 1.6 1.7 1.8"

More configs

Allow remote desktop (thanks to Bryan Ross) Edit: You may need to run CrashPlan once if the file doesn't exist
$this->bbcode_second_pass_code('', '# nano /opt/crashplan/conf/my.service.xml')
$this->bbcode_second_pass_quote('', '&')lt;serviceHost>0.0.0.0</serviceHost>

Remote Desktop

Connect to a Headless CrashPlan Desktop

On Windows:
Install windows client, close CrashPlan, edit ui.properties at C:\Program Files\CrashPlan
find
$this->bbcode_second_pass_quote('', '#')serviceHost=

I've found the error with libjtux, seems that it was missing sys/resource.h.
Compiled against Java 8 and tested it, it seems to be running with no issues.
I updated the the guide and added a link to my precompiled binary.


This guide can be used to install CrashPlan on different Arm devices than the Raspberry Pi.
Anyone who wants to do so will probably need to use openjdk6,
and of course to manually compile the different libs,
don't forget to point the location of openjdk6 @ /usr/lib/jvm/java-6-openjdk/ when editing the configs and Makefiles.

p.s.
When attempting to run CrashPlan on Arm device memory is the key factor,
128MB will not suffice, 256MB is the bare minimum and won't be enough for 100GB+ backup, 512MB probably will do.

Hi dhead666, thanks for the updated tutorial. my crashplan was running very slowly so i decided to take the plunge and try your settings.

i followed everything twice, including the java portion but i still have trouble running the install script. even though i edit the file to include 1.8, added 1.8 to the path, and followed very closely your instructions on download/installing the 1.8 jdk, it still does not want to install.

This is one I get

$this->bbcode_second_pass_code('', 'Welcome to the CrashPlan Installer.

Press enter to continue with installation.

Validating environment...
detected root permissions
47745 blocks
./install.sh: line 154: /opt/jdk1.8.0/bin/java: No such file or directory
The current version of Java () is incompatible with CrashPlan.
Please install one of the following version of the Sun JRE or OpenJDK: 1.5 1.6 1.7 1.8')

i assure you that when i browse over to /opt/jdk1.8.0/bin/java the file is there. i just cannot figure out why it will not continue.

thoughts/ideas?

You're not in the CrashPlan installation folder
do:
$this->bbcode_second_pass_code('', 'cd CrashPlan-install/')

[dhead666]

I've change a dropbox link from https to http to remove wget's no certificate error.
Also I added a remark about the export command on the Java installation section.

@jeanlouiejam,
I've followed my guide today with the latest CrashPlan installation script and had no problems at all.

p.s.
I'm officially out off the testing phase, currently synching my 200GB+ backup back to CrashPlan servers.
The data stored on an usb 3.0 drive connected directly to a PogoPlug 4 shared via nfs to the Raspberry Pi.
