CrashPlan packages for Synology NAS

UPDATE – CrashPlan For Home (green branding) was retired by Code 42 Software on 22/08/2017. See migration notes below to find out how to transfer to CrashPlan for Small Business on Synology at the special discounted rate.

CrashPlan is a popular online backup solution which supports continuous syncing. With this your NAS can become even more resilient, particularly against the threat of ransomware.

There are now only two product versions:

  • Small Business: CrashPlan PRO (blue branding). Unlimited cloud backup subscription, $10 per device per month. Reporting via Admin Console. No peer-to-peer backups
  • Enterprise: CrashPlan PROe (black branding). Cloud backup subscription typically billed by storage usage, also available from third parties.

The instructions and notes on this page apply to both versions of the Synology package.

CrashPlanPRO-Windows

CrashPlan is a Java application which can be difficult to install on a NAS. Way back in January 2012 I decided to simplify it into a Synology package, since I had already created several others. It has been through many versions since that time, as the changelog below shows. Although it used to work on Synology products with ARM and PowerPC CPUs, it unfortunately became Intel-only in October 2016 due to Code 42 Software adding a reliance on some proprietary libraries.

Licence compliance is another challenge – Code 42’s EULA prohibits redistribution. I had to make the Synology package use the regular CrashPlan for Linux download (after the end user agrees to the Code 42 EULA). I then had to write my own script to extract this archive and mimic the Code 42 installer behaviour, but without the interactive prompts of the original.

 

Synology Package Installation

  • In Synology DSM’s Package Center, click Settings and add my package repository:
    Add Package Repository
  • The repository will push its certificate automatically to the NAS, which is used to validate package integrity. Set the Trust Level to Synology Inc. and trusted publishers:
    Trust Level
  • Now browse the Community section in Package Center to install CrashPlan:
    Community-packages
    The repository only displays packages which are compatible with your specific model of NAS. If you don’t see CrashPlan in the list, then either your NAS model or your DSM version are not supported at this time. DSM 5.0 is the minimum supported version for this package, and an Intel CPU is required.
  • Since CrashPlan is a Java application, it needs a Java Runtime Environment (JRE) to function. It is recommended that you select to have the package install a dedicated Java 8 runtime. For licensing reasons I cannot include Java with this package, so you will need to agree to the licence terms and download it yourself from Oracle’s website. The package expects to find this .tar.gz file in a shared folder called ‘public’. If you go ahead and try to install the package without it, the error message will indicate precisely which Java file you need for your system type, and it will provide a TinyURL link to the appropriate Oracle download page.
  • To install CrashPlan PRO you will first need to log into the Admin Console and download the Linux App from the App Download section and also place this in the ‘public’ shared folder on your NAS.
  • If you have a multi-bay NAS, use the Shared Folder control panel to create the shared folder called public (it must be all lower case). On single bay models this is created by default. Assign it with Read/Write privileges for everyone.
  • If you have trouble getting the Java or CrashPlan PRO app files recognised by this package, try downloading them with Firefox. It seems to be the only web browser that doesn’t try to uncompress the files, or rename them without warning. I also suggest that you leave the Java file and the public folder present once you have installed the package, so that you won’t need to fetch this again to install future updates to the CrashPlan package.
  • CrashPlan is installed in headless mode – backup engine only. This will configured by a desktop client, but operates independently of it.
  • The first time you start the CrashPlan package you will need to stop it and restart it before you can connect the client. This is because a config file that is only created on first run needs to be edited by one of my scripts. The engine is then configured to listen on all interfaces on the default port 4243.
 

CrashPlan Client Installation

  • Once the CrashPlan engine is running on the NAS, you can manage it by installing CrashPlan on another computer, and by configuring it to connect to the NAS instance of the CrashPlan Engine.
  • Make sure that you install the version of the CrashPlan client that matches the version running on the NAS. If the NAS version gets upgraded later, you will need to update your client computer too.
  • The Linux CrashPlan PRO client must be downloaded from the Admin Console and placed in the ‘public’ folder on your NAS in order to successfully install the Synology package.
  • By default the client is configured to connect to the CrashPlan engine running on the local computer. Run this command on your NAS from an SSH session:
    echo `cat /var/lib/crashplan/.ui_info`
    Note those are backticks not quotes. This will give you a port number (4243), followed by an authentication token, followed by the IP binding (0.0.0.0 means the server is listening for connections on all interfaces) e.g.:
    4243,9ac9b642-ba26-4578-b705-124c6efc920b,0.0.0.0
    port,--------------token-----------------,binding

    Copy this token value and use this value to replace the token in the equivalent config file on the computer that you would like to run the CrashPlan client on – located here:
    C:\ProgramData\CrashPlan\.ui_info (Windows)
    “/Library/Application Support/CrashPlan/.ui_info” (Mac OS X installed for all users)
    “~/Library/Application Support/CrashPlan/.ui_info” (Mac OS X installed for single user)
    /var/lib/crashplan/.ui_info (Linux)
    You will not be able to connect the client unless the client token matches on the NAS token. On the client you also need to amend the IP address value after the token to match the Synology NAS IP address.
    so using the example above, your computer’s CrashPlan client config file would be edited to:
    4243,9ac9b642-ba26-4578-b705-124c6efc920b,192.168.1.100
    assuming that the Synology NAS has the IP 192.168.1.100
    If it still won’t connect, check that the ServicePort value is set to 4243 in the following files:
    C:\ProgramData\CrashPlan\conf\ui_(username).properties (Windows)
    “/Library/Application Support/CrashPlan/ui.properties” (Mac OS X installed for all users)
    “~/Library/Application Support/CrashPlan/ui.properties” (Mac OS X installed for single user)
    /usr/local/crashplan/conf (Linux)
    /var/lib/crashplan/.ui_info (Synology) – this value does change spontaneously if there’s a port conflict e.g. you started two versions of the package concurrently (CrashPlan and CrashPlan PRO)
  • As a result of the nightmarish complexity of recent product changes Code42 has now published a support article with more detail on running headless systems including config file locations on all supported operating systems, and for ‘all users’ versus single user installs etc.
  • You should disable the CrashPlan service on your computer if you intend only to use the client. In Windows, open the Services section in Computer Management and stop the CrashPlan Backup Service. In the service Properties set the Startup Type to Manual. You can also disable the CrashPlan System Tray notification application by removing it from Task Manager > More Details > Start-up Tab (Windows 8/Windows 10) or the All Users Startup Start Menu folder (Windows 7).
    To accomplish the same on Mac OS X, run the following commands one by one:

    sudo launchctl unload /Library/LaunchDaemons/com.crashplan.engine.plist
    sudo mv /Library/LaunchDaemons/com.crashplan.engine.plist /Library/LaunchDaemons/com.crashplan.engine.plist.bak

    The CrashPlan menu bar application can be disabled in System Preferences > Users & Groups > Current User > Login Items

 

Migration from CrashPlan For Home to CrashPlan For Small Business (CrashPlan PRO)

  • Leave the regular green branded CrashPlan 4.8.3 Synology package installed.
  • Go through the online migration using the link in the email notification you received from Code 42 on 22/08/2017. This seems to trigger the CrashPlan client to begin an update to 4.9 which will fail. It will also migrate your account onto a CrashPlan PRO server. The web page is likely to stall on the Migrating step, but no matter. The process is meant to take you to the store but it seems to be quite flakey. If you see the store page with a $0.00 amount in the basket, this has correctly referred you for the introductory offer. Apparently the $9.99 price thereafter shown on that screen is a mistake and the correct price of $2.50 is shown on a later screen in the process I think. Enter your credit card details and check out if you can. If not, continue.
  • Log into the CrashPlan PRO Admin Console as per these instructions, and download the CrashPlan PRO 4.9 client for Linux, and the 4.9 client for your remote console computer. Ignore the red message in the bottom left of the Admin Console about registering, and do not sign up for the free trial. Preferably use Firefox for the Linux version download – most of the other web browsers will try to unpack the .tgz archive, which you do not want to happen.
  • Configure the CrashPlan PRO 4.9 client on your computer to connect to your Syno as per the usual instructions on this blog post.
  • Put the downloaded Linux CrashPlan PRO 4.9 client .tgz file in the ‘public’ shared folder on your NAS. The package will no longer download this automatically as it did in previous versions.
  • From the Community section of DSM Package Center, install the CrashPlan PRO 4.9 package concurrently with your existing CrashPlan 4.8.3 Syno package.
  • This will stop the CrashPlan package and automatically import its configuration. Notice that it will also backup your old CrashPlan .identity file and leave it in the ‘public’ shared folder, just in case something goes wrong.
  • Start the CrashPlan PRO Synology package, and connect your CrashPlan PRO console from your computer.
  • You should see your protected folders as usual. At first mine reported something like “insufficient device licences”, but the next time I started up it changed to “subscription expired”.
  • Uninstall the CrashPlan 4.8.3 Synology package, this is no longer required.
  • At this point if the store referral didn’t work in the second step, you need to sign into the Admin Console. While signed in, navigate to this link which I was given by Code 42 support. If it works, you should see a store page with some blue font text and a $0.00 basket value. If it didn’t work you will get bounced to the Consumer Next Steps webpage: “Important Changes to CrashPlan for Home” – the one with the video of the CEO explaining the situation. I had to do this a few times before it worked. Once the store referral link worked and I had confirmed my payment details my CrashPlan PRO client immediately started working. Enjoy!
 

Notes

  • The package uses the intact CrashPlan installer directly from Code 42 Software, following acceptance of its EULA. I am complying with the directive that no one redistributes it.
  • The engine daemon script checks the amount of system RAM and scales the Java heap size appropriately (up to the default maximum of 512MB). This can be overridden in a persistent way if you are backing up large backup sets by editing /var/packages/CrashPlan/target/syno_package.vars. If you are considering buying a NAS purely to use CrashPlan and intend to back up more than a few hundred GB then I strongly advise buying one of the models with upgradeable RAM. Memory is very limited on the cheaper models. I have found that a 512MB heap was insufficient to back up more than 2TB of files on a Windows server and that was the situation many years ago. It kept restarting the backup engine every few minutes until I increased the heap to 1024MB. Many users of the package have found that they have to increase the heap size or CrashPlan will halt its activity. This can be mitigated by dividing your backup into several smaller backup sets which are scheduled to be protected at different times. Note that from package version 0041, using the dedicated JRE on a 64bit Intel NAS will allow a heap size greater than 4GB since the JRE is 64bit (requires DSM 6.0 in most cases).
  • If you need to manage CrashPlan from a remote location, I suggest you do so using SSH tunnelling as per this support document.
  • The package supports upgrading to future versions while preserving the machine identity, logs, login details, and cache. Upgrades can now take place without requiring a login from the client afterwards.
  • If you remove the package completely and re-install it later, you can re-attach to previous backups. When you log in to the Desktop Client with your existing account after a re-install, you can select “adopt computer” to merge the records, and preserve your existing backups. I haven’t tested whether this also re-attaches links to friends’ CrashPlan computers and backup sets, though the latter does seem possible in the Friends section of the GUI. It’s probably a good idea to test that this survives a package reinstall before you start relying on it. Sometimes, particularly with CrashPlan PRO I think, the adopt option is not offered. In this case you can log into CrashPlan Central and retrieve your computer’s GUID. On the CrashPlan client, double-click on the logo in the top right and you’ll enter a command line mode. You can use the GUID command to change the system’s GUID to the one you just retrieved from your account.
  • The log which is displayed in the package’s Log tab is actually the activity history. If you are trying to troubleshoot an issue you will need to use an SSH session to inspect these log files:
    /var/packages/CrashPlan/target/log/engine_output.log
    /var/packages/CrashPlan/target/log/engine_error.log
    /var/packages/CrashPlan/target/log/app.log
  • When CrashPlan downloads and attempts to run an automatic update, the script will most likely fail and stop the package. This is typically caused by syntax differences with the Synology versions of certain Linux shell commands (like rm, mv, or ps). The startup script will attempt to apply the published upgrade the next time the package is started.
  • Although CrashPlan’s activity can be scheduled within the application, in order to save RAM some users may wish to restrict running the CrashPlan engine to specific times of day using the Task Scheduler in DSM Control Panel:
    Schedule service start
    Note that regardless of real-time backup, by default CrashPlan will scan the whole backup selection for changes at 3:00am. Include this time within your Task Scheduler time window or else CrashPlan will not capture file changes which occurred while it was inactive:
    Schedule Service Start

  • If you decide to sign up for one of CrashPlan’s paid backup services as a result of my work on this, please consider donating using the PayPal button on the right of this page.

    Anyone else having issues with the client randomly disconnecting? I’m running 3.64-0028 on a DS415+ with the Patters embedded Java 7 (7u71). I have 2GB allocated in syno_package.vars (I’ve upgraded my DS415+ to 8GB memory). I can remote connect the client and it runs for a random period of time and then just quits. There are zero entries in the engine_error log. I have multiple backup sets due to the size of my backup.

      I’m having this issue as well. The service restarts regularly, and the client closes itself whenever the service restart occurs.

      Mike, I’d like to know what memory module you bought. If possible a link to the item in the online store where you bought it. I’m going to buy a DS1815+ and would like to upgrade the memory to at least 8GB. Thanks!

      Looks like this is a memory issue. I’ve upped the memory allocation in sync_package to 3072M and the client has been running successfully for over 1hr with no disconnects.

        Mike, I’d love to try this on our unit. Could you please direct me to where you changed that setting? I was unable to find any file with that name on the Synology device after poking around on the file system, but perhaps my Linux-fu is weak today.

    4. Mike

      Hi Eric

      You need to ssh or telnet into your box, and the file is /volume1/@appstore/Crashplan/syno_package.vars

      You’ll see an entry for USR_MAX_HEAP which you can modify. (Just make sure the line isn’t commented out, i.e. has a # at the beginning).

      You’ll need to restart the CrashPlan package on your box for it to read the new config.

        Mike, thanks so much! I’ve found the file (I guess my Linux-fu was indeed weak), and I’ll experiment with this. Might have to make a trip to get another RAM module, too.

      2. Eric Henson

        Mike, thanks very much for the tip. I wish I could report success, but uncommenting and bumping it from 512 to 1024 (our device presently only has 2GB RAM) produced no change in the resetting behavior.

    5. Mike

      If you’ve not already, I’d also try breaking your back up into sets. One strategy I also used when I was tight on memory was to bump up the memory allocation in increments until the disconnections happened. Then I’d set the backup sets to run at specific times overnight when the box wasn’t in use, and use the scheduling options in DSM to stop & start the CrashPlan package. That way I could allocate most of the boxes memory without affecting daily activities.

        Having the same issue here. My DS 412+ has 2 GB of RAM. Before updating to DSM 5.1 everything was working perfectly, heap size for 1024MB was enough for almost 1.000.000 files. Now it’s crashing constantly. I tried to set the heap size to 2048MB, then the backup is running fine again, but the RAM usage on my DS is 80-90% all the time affecting the overall performance, so this is not a choice. I’m removing some directories from the backup now, hopefully reaching a stable state with 1024MB heap size again.
        I’m really wondering, why this happened after the update to DSM 5.1, as before that everything was smooth and easy…

  2. Jeff Mason

    I’ve read the thread pretty closely, but couldn’t find any updates on the “High iSCSI Utilization” with in my case DS412+, CrashPlan (headless on DS412+). I definitely have high, 100% iSCSI utilization when CrashPlan is running. As soon as I shit it down utilization goes back to 1-2%.

    Any updates that I missed?

    Well, I followed the process and was able to get CrashPlan installed and running on my Synology DS413 on 11/08/2014, nd configured it from my Windows client fine, and had it backing up a modest test folder of some pictures. It ran for several days, but the last log entry is from 11/11/2014 saying “scanning for files completed”. I noticed today that it’s status was “stopped” so I tried starting it. It flips to running for a second or two, then goes back to stopped. No entries in its log file. Any thoughts, I didn’t make any changes to the NAS during that time.

    Update to my previous post: The problem with the restarting client has to some kind of generic problem. I drastically reduced my backup directories to 5 with about 400.000 files, and still with 1024MB heap size the client is crashing all the time. Again, before the DSM 5.1 update I was backing up almost 1.000.000 files with 1024MB heap size!
    Another test: Heap size 1500MB. Now it’s working again, but my RAM usage is at 84% constantly. I don’t think this is an acceptable condition on the long term…

    Anyone has any suggestions why this is happening and how I can reduce the RAM usage of the client? Does the Java version (6-7-8) affect the RAM usage? I’m currently using version 1.8.0_06.

    Hi: I have used CrashPlan on my PC and Macbook for a couple of years. I wanted to use it for my Synology as well. It is successfully installed and running on the NAS – but when I change the ui.properties on my PC client to add the Synology IP address, it seems that I can no longer back up my PC? Isn’t it possible to have both? Any assistance appreciated.

    I got a problem with crashplan. All is working on 4 NAS. But on a DS413, crahplan never worked. I never found the package in repo and i needed to install it manually.

    Then i can access crash, configure it, all is running well but when it finish to scan the files to save the backup never start. it s waiting for connection ( i test on crashplan server or another computer).

    Do i need to check a port is open or something like that ?

    patters,

    First, Thanks all your work on this.

    I installed crashplan using your instructions about 17 months ago. the version on my server is 3.6.3. Now the java packages are showing up but not the crashplans ones. I tried deleting the link to your packages, rebooting and re entering it. Still only your java packages. i’m running the most recent version of dsm, DSM 5.1-5004,and have a ds213+

    any suggestions?

    I was running Crashplan on a DS414, and it worked perfectly and I loved it. After upgrading to DSM 5.1 and Crashplan 3.6.4 it stopped working properly, it’s starting and stopping after a few minutes. When I try to go back to Crashplan 3.6.3 by installing crashplan3.6.3-merged-0027.spk I get the error: “There was a problem downloading crashplan-native-armv7l.tgz from the official download link, which was “http://packages.pcloadletter.co.uk/downloads/crashplan-native-armv7l.tgz” Alternatively, you may download this file manually and place it in the ‘public’ shared folder.”

    Unfortunately, that file is removed so I am not able to restore the old working version of Crashplan, is there a way to resolve one of these issues to get back to a working version of Crashplan? Thanks in advance and I love your work.

    I downloaded version 3.6.3-0027 (crashplan3.6.3-merged-0027.spk) and I can not install.
    Also, at the moment I do not have CrashPlan on Synology :( Any idea?


    Could not update “CrashPlan”.
    There was a problem downloading crashplan-native-armv7l.tgz from the official download link, which was “http://packages.pcloadletter.co.uk/downloads/crashplan-native-armv7l.tgz”

      Congrats! Hopeful after hearing of your success, I tried reinstalling as well. It didn’t seem to solve the problem, but I then also doubled the NAS’s installed RAM from 2GB to 4GB and increased Java’s heapsize from 512MB to 2GB, which has allowed us to resume our backup with no more crashing!

      I don’t know about the long-term viability of this fix, but I’m just happy to be backing up again.

    Upgrading tonight to Synology DSM 5.1, Intel architecture DS1512+

    Using either the package center, or trying to use the spk from your package area, I get a ‘This package does not contain a digital signature’ error, and the update fails.

    Reply
    1. ed

      That was quick resolution.

      There’s a new, or new to me anyway, Trust Level option in package center, General tab. Setting that to allow anyone allows the update to take. However, the update didn’t run. Not sure why. After 3 failed attempts I tried the combined package from your package center and manually installed. That ran, and backup complete. Go figure. Will Synology ever quit playing games on this package and just finally support it already. Without it, I’d just as soon toss this NAS in the trash.

        Interesting, come to notice it won’t run any longer, hasn’t since 4 days back when it ran successful the first time, backed files up, and now no longer runs. Trying to downgrade to prior version.

  14. Sid Mautte

    Anyone have any experience getting this to work with a pair of DS412+ configured in an HA cluster? Will the install via the primary interface cover both? Does the Crashplan need to be for 1 system or multiple to cover this scenario?

    I installed your package on a 1812+ with 2Gb of RAM and it has been running great for about a week but since I just rebooted my NAS, the package won’t stay running, it says it started but then stops again almost immediately. I’ve tried reinstalling Java and rebooted again but it still won’t run – any ideas for what else to check next?

      You could Instead just update the bin/run.conf file to point to a real existing @tmp folder,
      e.g. change “-Djava.io.tmpdir=/var/@tmp” to “-Djava.io.tmpdir=/volume1/@tmp”

      The real temporary folders are emptied on restart.

        A heads-up if anyone uses Richard’s solution.

        Looks like on re-boot, the @tmp directory you add at /var gets nuked at re-boot.(John B.’s comment now makes alot more sense)

        Have not tried updating the bin/run.conf file per John B.

    Apologies if this has been discussed elsewhere, but I can’t find it if it has been.

    In troubleshooting an issue I was having, I uninstalled/reinstalled the Crashplan Pro package and am now getting the message:

    destination unavailable — you have an older version

    This is a freshly installed 3.6.4 package and the GUI install on my machine is also running 3.6.4. DSM is 5.1-5004. Anyone else seeing this?

    Thanks,

    As an addendum to this…. I attempted to revert to 3.6.3 without success, so I uninstalled 3.6.3 (I couldn’t get it to run). I then reinstalled 3.6.4 and it prompted me for a username and password as if the configuration has been removed (which I had tried to do manually earlier by renaming CrashPlan in /volume1/@appstore/). After re-entering that, all seemed to be well in the world again–no more “older version” message. Fab!

    Hi,

    I have looked a bit a this topic because since the latest updates i have a constant crashplan restarting, making it unable to complete a backup.

    It’s running on a DS1010+ with 1gb ram. Crashplan was running fine but one day we noticed it had crashed. i couldn’t see the crasplan package on the package center ( old dsm version ) so i made all the DSM updates and reinstalled the latest crashplan package.

    I have a large set of files ( > 1.000.000 and more than 1Tb of data ). If i disallow the backup, it succeed the scanning and wait. But when it try to backup, the service restart after ~3 minutes…

    Any idea on how to fix this ?

    Reply
    1. John B.

      Break your backup into small backup sets.
      Start with a single small set and keep reducing it until it works. Only then add a single extra set and repeat as before.
      I’m not sure what a sweet-spot is for you, but I have 6 sets. One of them contains 25k files at 81GB (i.e. large number of files) and another one with only 363 files but at 1.2TB (i.e. few but large files).

      Reply
      1. Eric Henson

        I pushed off my similar issue by adding more RAM to the NAS, but I’m sure I’ll be dealing with this again one day as the backup size grows.

        John, I’d like to try out your backup sets solution, but I have a question about it. I presently have one very large set (~700,000 files at 1.8TB), and it’s backed up 70%. If I enable sets and then break this one up into multiple sets, am I going to have to restart the upload, or is CrashPlanPro smart enough to recognize it as duplicate data?

      2. John B.

        @Eric – there is a “Data de-duplication” setting in the Advanced backup settings.
        Personally, I’m using all types in my backup sets (Minimal, Full or Automatic), depending on what my needs are and what I am willing to wait for.
        I’m not sure what happens when you move a folder from one set to another, but you could test it with a smaller number of files.

      3. Eric Henson

        @John – Thanks for the encouragement to try! I broke my massive backup set into several smaller ones, and after a quick resync, it picked up right where it left off, with no progress lost! Disabling de-duplication (this is lots of archival data that doesn’t change) sped the process up from 2.5 Mbps to 15.0 Mbps. Hooray!

      1. Nicolas

        Hi,

        Thanks for the advice, i will test that right now.
        About dataset. If i remove a folder from one dataset and add it in an other data set, will i loose the versionning files infos of old backups ? the popup when un-selecting a folder is kinda scary about that.

    I have a DS213j which was working sweetly with crashplan on 5.0. I have tried lots of the suggestions above to no avail (tried to install an older package, uninstalling, installing, upgrading the crashplan PC client). I am now running the latest version of the headless client, JAVA 7 package and PC client. The engine basically stops a few minutes after starting and the log file is empty of any information. The front end client cannot connect I have only 512 mb of RAM and its not easy I believe to increase that. Is this the end of the road. 16 months left on a 2 year subscription. Ah well. if there any updates on this situation I would love to hear it.

    I’m Testing this out on a rackststion with the latest dsm and 16Gb ram. When I assign more than 3.5gm ram to the java heap setting then Crashplan will not start. I’m thinking there might be a 64bit java needed. Anyone have any experience with this? I have about 12TB to backup.

    I see only the ProE version on the Repo, am I doing something wrong? Thanks for taking the time to make these work!

    Hi there … are there any news regarding the PPC-problem? … I own a DS213+ and Crashplan is still not running … :-(

    Thanks for your work!

    Best regards

    I own also a DS213+ which runs on a PowerPC with DSM 5.1. So the newest version of your package (3.6.4 0028) does not run. It always stays in the mode “waiting for backup”.

    So I tried to downgrade to 3.6.3 0027 which installs without any errors. But after starting – stopping – restarting it does not download and install the upgrade to 3.6.4 from the crashplan server. Any idea why this does not happen? Last time I tried this (some weeks ago) it worked perfectly … :-(

    Okay, I’m past my wit’s end, and lapsing into despair. Adding RAM, increasing the heapsize, and breaking up the data sets worked for a while, but we threw some more data onto the NAS, and it’s back to crash loops.

    I further divided the backup sets such that no set is over 1TB (problems seemed to previously begin around 1.9TB or so), but now there’s no change. The client crashes out and restarts during the initial scan, and never makes it to backing up files.

    I’m out of ideas, and I’m ready to throw this box out a window. Does anybody have any ideas for a desperate man?

      Further research suggests that CrashPlan requires about 1GB of available memory for every 1TB to be backed up, regardless of backup set breakdown. The amount of archival data we have to backup therefore makes a Synology/CrashPlanPro solution unsuitable. Heck, the whole CrashPlan system is pretty unscalable if that’s the case. “Unlimited storage” indeed.

      Thanks to everyone for their help, but I give up. Time to explore other backup solutions.

        This is not correct. I have 11 TB. And this worked perfectly well with my DS412+ which used 2 GB for Crashplan. It is only the number of files per backup set which matters.

      2. Eloi

        14tb with 300k files over 6 backup sets on 2gb of ram so I believe this solution does work. Although it did crash sometime but oh well no cheaper option than crash plan to date that work with nas or should I say nothing work with nas except for crashplan unless you count Amazon glacier.

        Hi Eric, this “rule” isn’t true. It depends on the amount of files, the settings (deduplication/compression) and the file size. Really huge files need more RAM for compression and deduplication. A big number of files in one job needs more RAM for the selection/analyzing process. I save about 11TB on a DS1513+ with only 4GB of RAM. The jobs are quite different. A “office”-job (office documents) and some “graphics-jobs” (JPEG, TIFF, PSD, PSB files) with sizes up to 3GB per file.

    So, I have a DS413, and have had reasonable success with CrashPlan installed for the last month or so. But this weekend an update to DSM 5.1 was installed, and the machine rebooted, and now when I try to start the CrashPlan package it won’t stay running for more than a few seconds. No entries in it’s log file. Is this common, is there a fix?

    I have a Synology 214se and had everything working on DSM 5.1 until the 5004 update. Since DSM has updated, the crashplan app won’t run. Is there any simple way of getting it back to life? I tried re-installing Java SE 7, but it didn’t help. Installation according to PCload. Thank you!

    I just updated Crashplan on my Snynology 214+ running 5.1-5004 update 2. I also updated Java 7. Java 7 is running but Crashplan won’t start. When I try to run it manually I get the following message. “Failed to run the package service. Check package log……” Any ideas on getting Crashplan running again?

    On my stock DS412+, I’m currently running:
    DSM 5.1 Update 1
    Patters Java 1.7.0_71-0029
    CrashPlan 3.6.3-0027

    I’m being prompted to upgrade to:
    DSM 5.1 Update 2
    CrashPlan 3.6.4

    I’m thinking about staying where I am rather than risking breaking the whole thing. Constructive advice would be greatly appreciated!

    Hello i bought the new 215j and added the repo, but only 3 packets show ( open remote, minecraft, craftbukkit ). Does this mean the packages aren’t available for my processor (Marvell Armada 370 Dual Core)?
    Thanks for your work.

        I’ve just published an amended Java package for Armada 375. Can you check it works by ensuring you get the JVM and Hotspot versions displayed in the log section of the package? Once that’s confirmed working ok I can get support added to the other packages.

      Ok i tried installing Java 7 but it failed. I created the public folder and put ejre-7u71-fcs-b14-linux-arm-vfp-hflt-server_headless-26_sep_2014 in it before, compressed or decompressed same result.

    hi, all good,
    but after a reboot, the backup folders appear as “missing” on the crashplan desktop.
    but when I click them, it opens the NAS filesystem and the folders appear as selected.

    any advise?

    Thanks

    I tried the CrashPlanPRO package and it seemed to be working, but upon rebooting the synology server the application does not restart. I tried restarting it manually using the start-stop-status script, but it reported directory errors. I uninstalled PRO then installed basic CrashPlan and it does restart when the server reboot.

    I think the PRO startup script has a bug.

    Hi All!

    I successfully added the repository and was able to install Java (I took Version 7) and checked it is running. When I navigate to Community I see “Bliss, CraftBukkit, Java 6/7/8, Minecraft, Openremote and Servilo”, but Crashplan is missing! :-(
    I updated the package list, restarted my DS (it’s a DS413 with DSM 5.0-4528 Update 2) with no luck – the Crashplan Client is still not visible! :-(

    Can anyone PLEASE help??!?

    Cheers,
    Jens.

    Has anyone updated to DSM 5.1-5021? Any problems with Crashplan following the update? Crashplan been very stable for me on 5.1-5004, so just trying to avoid problems on DS1512+.

    I updated my DS214play to DSM 5.1-5021 and after that CrashPlan did not start, it also switched to stopped state as soon as I tried to start it manually. So I tried to re-install it but I only got an error message that said something like “Failed to install CrashPlan” following very soon after having accepted the CrashPlan Disclaimer.

    What I found out was that I needed to set the Trust Level to Any Publisher while doing the install. (I must have switched it back to “Synology Inc.” after I did the original install.).

    It now works perfectly again.

    Thanks for providing this excellent package!

    OK, looking for more information on whether I should update CrashPlan to 3.6.4 on my DS412+ or leave well enough alone at 3.6.3. What does the update give me that I’m not getting now?

    Reply
    1. WiFied

      3.4.6 working great on DSM 5.1 for me. There are release notes on the Crashplan website that outline the changes in 3.4.6 – security updates alone are reason enough to update.

    Hi,

    I’ve always had problems with crashplan not starting after rebooting. I’ve got a DS415+, and it looks like /tmp/@tmp is missing after a reboot.

    I edited /var/packages/CrashPlan/scripts/start-stop-status.sh and added a line near the top before the definition of TEMP_FOLDER that reads:

    test ! -d “/tmp/@tmp” && mkdir /tmp/@tmp

    which seems to be much better.

    FYI, in case others are having the same problem.

    Hello,
    I’ve just updated my DS1513+ (intel) to DSM5.1-5021 and then I’ve uninstalled/installed Java 6 package (I didn’t download the java file from Oracle again, I assume it hasn’t changed and I get no error to install Java 6). But now CrashPlan is stopped and choosing run has no effect. I’ve seen other people with the same problem in previous comments that are on different architectures and Java version. Any clue where to look for ?

    The package breaks on the Crashplan Proe 3.7.0 update from Code42. The update is downloaded, then the logs says “Synology repairing upgrade in /var/packages/CrashPlanPROe/target/upgrade/1388728800370.1419325211508” – and it never restarts
