I’m attempting to run CrashPlan on my new My Cloud 2T drive. I’m using the OpenJDK java java version “1.6.0_27” OpenJDK Runtime Environment (IcedTea6 1.12.5) (6b27-1.12.5-1) OpenJDK Zero VM (build 20.0-b12, mixed mode) And am using the jtux.so from a Raspberry Pi install. I’ve stopped most of the processes (apache2, wd* ) and adjusted the -Xms down to 96m, 128m, 148m, 196m but still get crashes with what looks to be out of memory. I see that some people have CrashPlan running on My Book Live and am curious how stable it is and what version of java you are running. thx, bob
Responding to my own post: I changed the OpenJDK to a Oracle implementation: java version “1.7.0_51” Java™ SE Embedded Runtime Environment (build 1.7.0_51-b13) Java HotSpot™ Embedded Client VM (build 24.51-b03, mixed mode) using the following package: ejre-7u51-fcs-b13-linux-arm-vfp-hflt-client_headful-18_dec_2013.tar.gz I set the -Xms back to 256m and this thing is amazing I’ve run 2 different computers syncing to the My Cloud box, one hardwired (gigabit switch) and one wireless. The CrashPlan app has been up for a day and 1/2 before I did a ‘unplug while backing up’. I’m happy to say that the My Cloud and CrashPlan restarted without a hitch and I’m backing up again. All of the WD apps are running and I’m very happy with this as my remote backup solution. The next test is to take it to the remote site and see how it works there. For the price (150 bucks for 2T) this is a very viable 3rd tier backup solution.
Could you provide some more detail on the steps you took to get CrashPlan installed? I’d like to do the same and have the My Cloud backup directly to CrashPlan. Thanks.
I would be interested to know how you got this working as well. I have the 4TB version of My Cloud, and followed these instructions for MBL in vain: http://community.wd.com/t5/My-Book-Live/GUIDE-Installing-CrashPlan-for-MBL-Cloud-backup/m-p/561614/highlight/true#M21307 .
Obviously that guide wasn’t written for Mycloud, but everything worked up to the point of starting crashplan, where I got the java.lang.UnsatisfiedLinkError because of libjtux.so. Can you tell me where you got your version of libjtux.so?
For anyone who is stuck on this, I finally got it working by following these instructions as stated earlier:
http://community.wd.com/t5/My-Book-Live/GUIDE-Installing-CrashPlan-for-MBL-Cloud-backup/m-p/561614/highlight/true#M21307 . Then I found an armv7l (armhf) compiled version of libjtux.so here: https://github.com/downloads/swenson/jtux/libjtux.so which I stumbled upon from the comments section of this raspberry pi / crashplan tutorial:
http://www.jonrogers.co.uk/2012/05/crashplan-on-the-raspberry-pi/ . That Jon Rogers link also has some info on changing out Java to increase the performance of crashplan (apparently significantly).
So I have it working. If anyone has questions on what I did, please reply.
Thanks mtvann for the info and congrats on getting it working. I’m going to give it a try, but a few questions before starting.
- Did you install the latest version of Crashplan? There is a note in the Jon rogers link saying to use a previous version that introduced some doubt.
- Did you make any changes to Java per the other posts, or just follow the instructions exactly as in the MBL post?
- Does Crashplan start automatically or does that need to be configured somewhere?
- Did you backup any of the My Cloud configuration files before you started the installation?
Thanks for your help!
Just chiming in on this topic also. I found this guide for installing Crashplan on My Cloud Drive which has been working pretty great. I have had a few issues where the Crashplan service on My Cloud would stop working and I would have to issue: /usr/local/crashplan/bin/CrashPlanEngine start - via ssh to get it going again. This was during the initial backup of files which was around 100GB in size.
Now to figure out why my backups from the My Cloud Drive to Crashplan servers are not working…
@Rustybones - Thanks for the pointer to the guide. With it I was able to get Crashplan installed and running. My Cloud has been uploading direct to Crashplan’s servers for several days now without any hiccups.
My only complaint is that the upload speed is rather slow. Usually it is running at less than 1Mbps. At one point I saw over 20Mbps but that didn’t last more than a few minutes and has not repeated. My network connection is plenty fast so the bottleneck is either in the My Cloud or at Crashplan’s servers. A link in the guide you referenced suggests that the version of Java makes a difference. I’ve tried 1.6, 1.7, and even 1.8 all with very similar results so at least for me the version of Java does not make any difference in the speed.
What kind of upload speed are you or others seeing?
@buchant - Which folder location do you set to backup up to CrashPlan Central. I ask because I have all my home computers backing up to a shared folder on My Cloud called Backups. I can navigate to this folder and see that there is about 100GB worth of data. But when I select the ‘Backups’ folder through the CrashPlan GUI to backup to CrashPlan central, CrashPlan tells me it’s on 1KB…
I’ve tried: nfs > Backups, shares > Backups, DataVolume > shares > Backups … all of them result in the same thing… 1KB 
Any ideas?
@Rustybones At the moment I’m backing up two shares. /shares/Public and /shares/MediaLibrary which is a share I created. There are around 50K files in MediaLibrary all seen by Crashplan (~400GB). Are you using a backup program to backup your computers to the My Cloud. It’s possible that Crashplan is filtering out your backup files. This linkmay help.
Hmmm interesting, thanks for the link.
I’m using Crashplan on my home computers to backup to Crashplan running on the My Cloud, which stores that data in a folders called Backups. I then set CrashPlan running on the My Cloud to backup the “Backup” folder to CrashPlan central…
Maybe instead I need to make CrashPlan on the home computers backup to a network share stored on the My Cloud then make CrashPlan running on the My Cloud backup that network share.
Just curious how everyone is doing backing up their MyCloud network drive to crashplan. I see that there is a link in the first thread, but it may not be full-proof. Has anyone had success using any of these?

I ask so that I don’t waste time trying them 
Thanks!
@NYTerabyte - Follow the link in message #7 on the first page of this thread. It worked for me. I’m backing up directly from the My Cloud to CrashPlan. The only complaint is the speed of backup is slow, around 800Kbps to 1Mbps. I think the speed is limited by CrashPlan and not by My Cloud. Don’t bother with the suggestions to use a different version of Java. It made no difference in the speed of my backup.

Sweet! Great tip! Thanks! Already installing! Very very important for me since it’s well over 1tb of pictures and videos and they were scattered all over USB drives and I totally misunderstood the MyCloud drive capability.
I’ll feel so much safer once the data is back backup up again… Back to installing! I’ll post my results! Thanks again!
I’ve been trying for 2 days to get this installed. The slow performance makes it nearly impossible. Is the drive’s system performance slow for all drives?
At what installation step is performance a problem? There is no individual step that should take more than a minute.
It may help to turn the scanning processes off. http://community.wd.com/t5/WD-My-Cloud/Hidden-wdmc-directories-created-by-mcserver-and-photodbmerger/td-p/682091
from the very first step. It literally takes up to a half an hour to run. Seems to serve up movies just fine without any issues, but working in the cli is painful. Load averages are always relatively at the numbers below
load average: 14.44, 15.85, 15.42
Stopping these services made no difference
/etc/init.d/wdmcserverd stop
/etc/init.d/wdphotodbmergerd stop

Any ideas?
That looks very different from mine where nothing is over a few percent cpu except Java (CrashPlan running). Sorry but this is beyond my ability to help. Maybe someone else can offer some suggestions.
Thanks I’ll give that a shot!
So CPU loads are down and I’m attempting the install, but seems to be failing due to dpkg or some other issue. I’ve searched the net a bit, but cant seem to narrow down the problem. Any ideas?
