Or I see this:

It seems like it's still running off of the JDK 1.7, no? Try to uninstall the EJRE installer and do the java -version thing after that and see what you get.
Had the same problem in Ubuntu 13.04. Installed latest OpenJDK (1.7.0_25), but installer returned the message
Error: Could not find or load main class com.code42.utils.JavaEnvironment 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
I inspected the install.sh and found a variable JAVA_SPECIFICATION_VERSION that didn't seem to contain any value, probably because the com.code42.utils.JavaEnvironment class fails to load.
If you are absolutely sure that your Java-installation is OK, then you can read on.
The script compares the version list "1.5 1.6 1.7" against the previously mentioned variable, but since it doesn't contain anything (hence the empty parentheses in the error message) the script fails.
What I simply did to try to get CrashPlan installed was to add JAVA_SPECIFICATION_VERSION="1.7" below OKJAVA="1.5 1.6 1.7" in the script (line 21). Hadn't too much hope to get it installed properly after running install.sh, but the installation finished with no errors.
The client loads fine, and I can log in to my account and add files with no problems.
Here is something for anyone who has experienced problems with a full OS partition (i.e. when things are no longer working as they should and NASMON* displays "Disk Usage: / 100% (4.0G)" in the top righthand corner) or who would like to avoid it: :arrow: do not accept the default install directory for the crashplan cache:
What directory do you wish to install CrashPlan to? [/usr/local/crashplan]
When my OS partition was full a couple of days ago and I had to let Netgear support fix it via remote access, the technician told me that the reason for the full OS partition was that a process called "crashplan" was writing cache files (a total of 2.7 GB) into /usr/local/crashplan, causing the root partition to fill up.
Unfortunately, I'm not an expert with servers (I don't even know exactly which directories are located in the root partition), so before I start fiddling around with things, I'd like to ask here:
:?: What other directory would be appropriate? Does the install directory affect the functioning of crashplan at all? :?: What can I do now that I already installed crashplan according to the instructions given in this thread? Can I somehow move the installation or do I need to uninstall and re-install completely?
Cheers, Christoph

(a) stop crashplan (you can stop the service if you double-click on the house in the crashplan client - that will give you some extra commands). (b) rename \usr\local\crashplan\cache to something else (\usr\local\crashplan\ocache for instance). (c) create a cache folder on \c\ (perhaps use frontview) (d) create a soft link (http://www.cyberciti.biz/faq/creating-s ... olic-link/) ln -s \c\cache \usr\local\crashplan\cache (e) restart the NAS to restart the crashplan service.
I'm not certain this will work, but I would try it before doing a full reinstall.
Another option is to create \c\cache, and edit myservice.xml to point to it (replacing the reference to \usr\local\crashplan\cache).
The crashplan logs can also be moved, though they are less problematic than the the cache.
This got me interested. Found this on their site for those who would like to clear the cache. It doesn't solve your problem, but it might be useful information for those watching this thread. 🙂
Oops, scratch that. I think I misread it. It's 3.5 MB, isn't it. :oops: :lol: Seems my installation hasn't run amok after all. It's Friday and I'm tired hehe.
Hi. Great guide and I'm almost there (I think) but I'm having a bit of a problem connecting to CrashPlan when trying to configure the NAS. When I fire up the desktop client without any modifications to ui.properties on the desktop PC, it will log into CrashPlan fine. However, whenever I change the service port to 4200 and do the tunnel through Putty, the desktop client will fail when trying to log into CrashPlan (tells me that the credential are wrong or that I need to check my network). When trying to login, this is what appears in the logs on the NAS:

Please disregard my last post. Seems that I had the Pro version of CP installed on my desktop, and the 'consumer' version installed on the NAS. Uninstalled CP on the NAS, then installed the Pro version and all connected fine. Great guide!
I just setup my 316 and would like to get CrashPlan running on it.
What would the process be for getting the right version of the JRE on it? I am not sure the EJRE approach here would work, the other thread mentioned adding a new target and using apt-get.
So, went ahead and did that, but java -version still shows old version.
Right now dpkg is showing: openjdk-6-jre-headless:amd64 install openjdk-6-jre-lib install openjdk-7-jre-headless:amd64 install openjdk-7-jre-lib install
upload speeds vary quite a bit on my Pro. Over the weekend it uploaded about 16 GB @ 35 mbits, but a day later uploaded 2 GB @ 5.2 mbits. I'm not sure if the variation is in their servers, or simply the fluctuations of the internet.
Though 5.2 mbits is not typical, it is far more usual for it to be in the high teens at least. (My internet service is 75 down/35 up, so 35 mbits is about the max I'd see on the upload).
I did upgrade the memory to 2GB, which seemed to make a difference.
I changed depue to minimal, and compression off. There were no bandwidth limitations in the crashplan. Currently getting about 400-500KB/sec. A little better but not great.
Load on the nas if around 1, and there is really no disk thrashing (memory used is about 50%, and swap is not being used)
If it doesn't seem to pick up over time, then you could try restarting the service. Double-click on the house on the upper right corner, and it will give you some command lines.
Also, I've found it useful to "tail -100 \usr\local\crashplan\log\backup_files.log.0" from ssh (putty window maximized first). It gives a better picture of what's happening than the client.
I think it took about 3 months to upload 6 TB of data initially. Though my pro-6 definitely has a faster CPU than the ultra.
I added one share at a time to the backup list (doing more critical data first).
It's been a while now, but I think I made two other changes:
(a) I increased the virtual memory in /usr/local/crashplan/bin/run.conf to -Xmx1024M (b) I added a few more containers to the <noCompressionPatterns> xml in \usr\local\crashplan\conf\my.service.xml. This include .mkv, .m2ts, .ts, .iso,, .evo, and .tib. At the time, that seemed to make a difference in the upload speed for those file types.
I'm in the crash plan trial right now. Very nice and I can't believe this is only going to be ~$5/month. Two things I've noticed: 1) large files are transferred more slowly, and 2) My rates vary over time of day. I've got 75/10+ and I've seen transfers in the 12-13Mb/s that I had to throttle or my kids were complaining, but most of the time I'm seeing 2-5. With large file (videos) transferring in the 2 range. When I add a directory of photos they go much faster. Both of these could be somehow due to Comcast though. I know that comcast does a boost for the first 25MB of every connection. If it creates a new socket for each transfer it could be a big win for small files. It's difficult to tell where the throttling is. But hey, I'm not complaining this seems a little too good to be true. Hopefully I'll never have to do a big restore.
I have been running CrashPlan on my ReadyNAS pro4 for a little over a year without any issues. It is located in my office and serves as an offsite backup for family. I would like to add my own home computer (OS X 10.9) to it. Being that the backup is ~400GB I would like to pre-seed the backup using an external USB HDD.
I am following this: https://support.code42.com/CrashPlan/Latest/Backup/Backing_Up_Very_Large_File_Selections_To_Another_Computer
I am unable to copy the crashplan archive folder to "/c/crashplan" on the NAS. It says I do not have permission. I am unable to write anything to the /c/crashplan directory. Before I start editing share permissions through Frontview has anybody else run into this? Did you find a solution?
Frontview shows default permission for Crashplan as Read/Write and allow Guest access is checked.
What is currently in /c/crashplan? Maybe that is where you installed crashplan? I never created that directory in my pro6 setup. If it is your install directory I wouldn't open permissions on that. The easiest thing to do is:
1. create a new share called backups and a subdirectory inside that for each computer you are backing up 2. add permissions for the share 3. copy your seed to that computer's subdirectory. 4. add that directory to your crashplan list of directories to back up.
