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.

    I’m one of the unfortunates with a non-Intel Synology. I installed the older version on my DS213 and all seems fine at first however Crashplan automatically updates to V4.8 after a short while. Anybody know how to Block Crashplan upgrading from 4.7 on Synology and Windows client that I use to view activity?

    Thanks!

      Can’t find the thread with my phone but search here and you will find it.

      In general what you need to do is rename the existing update folder to say update.tmp. Create a new one called update. Then do chmod 444 update so CP won’t be able to use that hence update will be blocked.

        Eamon, Dimi,

        I took this approach (I own a 212j, non-intel) with no luck. Every time CrashPlan starts, it will try to download the latest version, which is expected.
        However, and since it won’t be able to do so, CP will wait 1 hour to try and download the update again but without starting the backup engine.

        If either one of you manage to make it work, can you post your steps here?
        Thanks,

        Nicolas

        What I did was the following (I have an Intel one so might be different)
        I installed the package from patters but did not start it after installation.
        Then I renamed the upgrade folder in /var/packages/CrashPlan/target/upgrade to /var/packages/CrashPlan/target/upgrade.tmp
        Then I created a file called update using sudo touch update
        Then I did
        sudo chmod 444 update
        Then I started the package. This has prevented CP from upgrading.
        Waiting for Patters to update the package.

      3. tam

        I have a 212j (non-intel) as well. I tried these steps and I’m having the same problem as you, with hourly failed attempts to upgrade and no backup running as far as I can tell. Were you ever able to get this to work?

        Even if it were to work, how do you manage your backups if it is on 4.7? My desktop client has already upgraded to 4.8 for my personal computer’s cloud backups.

      4. George

        Nicolas,
        I am backing up from clients to the NAS (not using Crashplan Central) and backup engine starts. Yes, I see the upgrade attempts, but when I start CP, backups execute on my clients. I shutdown CP (using cron) when backups are complete so CP does not continue to try an upgrade for the rest of the day. Awkward, but works for me.

    2. sadler

      I’m sorry but I don’t know how to start a new question so I hit reply.
      I use Crashplan on all my windows PC’s. I have just successfully set it up on this PC to backup my Synology 1515+ and I can see that the crashplan icon is check the selected NAS directories to back up to the cloud. However how can I be sure that my PC is still being backed up to Crashplan as the Crashplan tray icon is now referring to the NAS. Do I need to change the config file back? Which ones?
      Thanks for your help

        Hello Suzanne,
        So you had crashplan configured on your NAS and now you have CP installed on your Windows PC with mapped shared and you CP installation on your PC is supposed to backup these shares?
        I would suggest to uninstall CP from your NAS, uninstall CP from your PC and start again from the beginning.
        Hope this helps.

      2. sadler

        Hi Dimi,
        Thanks for your help. Somehow magic happened, I rebooted my PC and now I see that CP is running on both the PC and the NAS. So the instructions from PCLoadletter have been fantastic.

    I sure hope Patters is OK! I don’t know if he’s ever gone so long after a new CP version without a single word, even if just to say he’s too busy to work on this now. Maybe after the holidays he’ll let us know at least he’s OK. He’s been fantastic to work on this for so many years.

    Merry Christmas to all and to all a good night!

        Mine broke with the last CrashPlan update (early Nov, maybe?), but I followed some advice here and got it working again. I was just concerned about Patters’ silence and I hope everything is OK with him.

        Thanks, though, for your offer to help! Happy holidays!

    Just for info, I’ve been unable to connect to headless engine, which was running fine on the syno, checking listening service was also ok, I could connect from my PC but impossible to connect with the Crashplan client, I created the .ui_info in C:\Program Files\CrashPlan, nothing worked.
    Then I’ve seen that there was also a C:\ProgramData\CrashPlan with an existing .ui_info, and same files in ./conf. Editing those files allowed me to connect to the distant engine… just for info ;)
    This being said thanks for the nice package :D

    Hi, i have been using this for long of time,but recently the package did not want to update at all, so i uninstalled it (as i did many time before) – now i can’t find it in the community package list?

    I can fine find your JAVA and other packages but the packages for CrashPlan is gone? IS DS413 not supported anymore ?

    I was playing yesterday again with crashplan on the synology.

    and it started to upgrade, so I applied the fix again.

    However, I am now unable to connect, I am using linux 4.7.0 client, but after chosing existing account, I get a message upgrading crashplan?

    does anybody know, how to prevent this? So I can configure it again?
    I can see from the crashplan logs on the synology, I am connecting, but how to prevent this upgrade attempt.
    I tried to google etc. and have been working on it for hours, but I am now kind of stuck….

      I have the same situation on Ubuntu. The headless client connects to the Synology, prompts me for credentials, and then gets stuck with the “Upgrading CrashPlan” message.

      The ui_user.log.0 file indicates that the Synology-side service isn’t accepting connections while it tries to upgrade (CPErrors.Global.UPGRADING).

    I’ve upgraded my crashplan on my synology NAS and it seemed to worked as usual. I’ve also updated the files in the conf folder on my client but after this, the this did not go as expected. After starting the client, crashplan client also installed an update.
    After the updated, I checked the UI.properties files and .ui_info in programdata and set them to the correct values. After restarting the client, things went wrong. It did not recognize the exiting backup and I inherited the previous backup. This also did not work correctly. My configuration looked correct, 4 backups referring to the correct folders but the first backup was renamed and when checking the underlying folders, they referred to my laptop and not to my NAS. This resulted in the status ‘missing’ when resynchronising the backup.
    I’ve created a ticket with Code42 but did not get a reaction yet.

    I finally decided to upgrade CP and it all went well without any issues. I also applied the upgrade block fix in case CP decide to screw it up again.
    mv upgrade upgrade.tmp
    touch upgrade
    sudo chmod 444 upgrade
    But I am looking at other ways to backup as this CP saga is taking so much of my time and money as well… with the GBP slump CP is costing more.

    ARM user here. I have uninstalled and reinstalled CrashPlan to 4.7.0-0041 on the NAS. The two local computers that backup to it are running 4.8 and are synced with CrashPlan Central. After the reinstall of 4.7 on the NAS, the upgrade prevention via permissions, the token update, etc., I now have two “Diskstation” destination entries available – one is the original that states “No connection for 65.7 days” (The date of the 4.8 ARM snub). The second is the newly reinstalled Diskstation. It states “Destination unavailable – backup location is not accessible,” but I am definitely connected to it and the DiskStation also reports it is running (I stopped and restarted it at one point as well).

    Changing the ui.properties and .ui_info to the NAS IP and accessing the NAS setup via the CrashPlan UI, I have an adopt setting available at the top – but it times out trying to get a list of computers to adopt (I assume I can use this method to tell it that the current Diskstation is the same as the old Diskstation provided it doesn’t timeout).

    Can I either:
    1: Fix the destination unavailable issue, remove the original Diskstation computer entry and backup again
    2: Get the entries back down to one by doing an “adopt” (or something similar) and then backup the differences over the last 65+ days?

    I can go for either – I would just like it to work. I hope for the moment having two desktops running 4.8 and backing up to a NAS running 4.7 will work. Appreciate any suggestions.

    After overcoming all the upgrade issues, I think CrashPlan has finally beaten me. My DS1812+ now no longer has enough ram for CrashPlan to run, despite having 4GB ram. Crashplan suggests 1GB ram for each 1TB/1 million files. I have at least 10TB of data and I guess I’m lucky to have gotten 95% of my data uploaded. I don’t think I can set my java heap high enough to avoid the outofmemory errors. What would the highest possible heap setting be for a 4GB unit?

    I thought breaking up my backup into backup sets or staggering the backup schedules would help but CrashPlan support says that no matter what, the entire file manifest still need to be loaded into ram. I’ve turned off all services on my NAS and even tried disabling deduplication, compression, and encryption to try to reduce ram usage.

    So the amount of RAM a NAS supports is the limit of how much data you can have on the NAS (for CrashPlan’s purposes)? Anyone give up and install CrashPlan on a windows box, map a drive to the NAS, and adopt the backup? Would that even work given the differences between paths in each backup set?

      Hi, yes I did exactly that – I installed a Linux (Intel) box and called it the same name as my NAS – recreated the file structure with NFS mounts to the NAS shared folders. I did manage to adopt a backup OK and never had any issues with CP after that. I think the functionality is reduced in terms of realtime access to the file system. I’ve since changed to a QNAP NAS box with CP running fine. My backups are much smaller than yours about 1.5TB.

      1. Robert

        Thanks for the tip! Using linux would be much easier to adopt the old backup than trying to do the same with Windows. I pieced together a linux system from spare parts and now it’s basically running in a cardboard box. Installed Ubuntu desktop, crashplan, connected to nas with nfs, and adopted the old backup. Currently using my TV as a monitor until everything is ok and I can make it headless.

        I hope 8GB ram is enough (double from nas, but I’m sure ubuntu is more bloated than the synology os) but at least I have the option to add more if needed. According to crashplan guidelines, I would need 12GB for my 12TB backup. We’ll see. I think many people will have the same issue once they start to max out the storage capacity of their NAS.

        Only unknown is how much storage crashplan will need for caching, so I went with a 40GB drive instead of trying to run ubuntu off a sdcard.

    Today my Syno tell me that there’s an update available to the CrashPlan package. I’m already running the 4.8 package that Patters released last week, and I haven’t seen anything here about a newer version, and since it’s currently working just fine, I’m in no rush to update it!

    Thanks for the continuing package work on CrashPlan for Synology — it rocks.

    I am trying to understand the tradeoffs in installing the latest upgrade, 044, which says that it bumps java from v111 to v121. If the upgrade is a single button press, then I would go for it. If it’s like the last upgrade, which requires jumping through hoops, copying files and keys around, etc., then I would probably opt to wait for one where CrashPlan has to be updated to talk to CrashPlan Central. Any advice appreciated!

      It will require you to fetch the java file (if you want a dedicated Java 8 install just for CrashPlan) – e.g. if you need to also install Java 7 for some other package requirement.
      If you don’t need this, then don’t bother upgrading. There is no other change.

    I’m another ARM user, my 4.7 Crashplan was backing up happily until a week or so ago, then it upgraded itself and stopped. I blocked the upgrade, but backups failed to run. And the client updated itself automatically as well. So I bit the bullet and migrated from an ARM DS214 to an Intel DS 216+II. Migration from the old DS to the new DS went without a hitch, installing the new Java package and the Crashplan package went perfectly as well. Thanks, Patters!
    I’m stuck on the client configuration. The client began local backups from my Windows system without my asking it to, and when I log in and try to adopt the DS, the client doesn’t list it the DS for adoption,just local ones. I reset the .ui_info and ui.properties files to the new DS IP address and token, but that doesn’t fix it.
    I assume there is cached information I need to delete to clear the bogus local backup locations and find my DS backup information. Anybody know where to look?

    1. tomwhelan

      After resetting the client configuration and restarting, the adoption list has changed.
      The first item is:
      Name Last backup
      Desktop 8 days ago 1.2TB @ Crashplan Central
      That’s the right size, but the name should be my Diskstation, but it doesn’t – it has my Windows system name. Any suggestions? Is there more client data to fix?

    Having trouble with this package after not having used it for about a year. Updated via DSM package manager, using dedicated java binary in /volume1/public.

    Package manager says that CrashPlan is running, but netstat -pat | grep 4243 shows nothing, ps | grep java shows nothing, and /var/lib/crashplan doesn’t exist. /var/log/messages says:
    entry.cgi_SYNO.Core.Package.Installation[1].install[8620]: pkginstall.cpp:405 Failed to run preinst script for CrashPlan, [1]

    Any ideas?

      Or is there a way to ensure that the package is completely uninstalled and there are no remnants that would be causing issues?

        Just an update – I solved my problem by uninstalling the CrashPlan package and deleting the crashplah shared folders (I had two), then reinstalling the CrashPlan package.

      I can verify this does not happen to me, and I also use the i586 version. I receive the file with the proper filename ejdk-8u121-linux-i586.tar.gz when I download using Firefox.

    DSM 6.1 is available. Just upgraded my 1513 and no issues so far. Crashplan started up ok, clients connect, etc.

    Not actually made the GUI connect to the backup engine, but that’s just laziness on my part.

      CrashPlan is working fine on my DS916+ after upgrading to DSM 6.1 – including connecting to the backup engine with the GUI.

      Seeing the same issue here. I’ve been using Crasphplan as a backup destination without any issues but now want to backup some files on my Synology 1815+ to Crashplan. The crashplan client just sits there saying “connecting to backup destination” and never actually starts a backup.

    I upgraded my DS415play to DSM 6.1 today, which broke the Crashplan 4.8.0-0044 client – just wouldn’t start.
    I uninstalled and reinstalled, but the CP client told me that the wrong version of Java was installed – I had both the Synology Java 7 and Java 8 packages. I removed 7.
    CP now told me that JAVA_HOME was undefined, so uninstalled and reinstalled Java 8.
    Voila, all working again.

    Something odd has been happening for me over the past few weeks after upgrading the DSM (713+) and CrashPlan app. Each time the windows app runs, it crashes while or shortly after scanning for files. Then it won’t reconnect next time I start the app. When I ‘echo cat’, I get a different port number (4269, 4271, etc) and token value. I’ve uninstalled both the package and the app multiple times and reinstalled following these instructions. Thoughts?

      I’m having the same problem. This is realy annoying especially the different port. I have friends backupping to my NAS and I have to adjust my firewall everytime (4242 external into new 4245 port internal).

      Someone any idea?

    Does anyone know how to get the “Watch file system in real-time” setting working? I am currently running the “Verify selection” on a daily basis to get everything backed up, but with close to 7TB of data it takes half the day to finish.

    I just thought I’d add my latest story to the mix… After persevering with Crashplan on Synology/Xpenology for about 5 years now, I’ve finally given up. I moved to Synology Hyper Backup To Amazon Cloud. Same yearly price for unlimited backups ($59 or so) and so far, it has saturated my upstream continuously at 20Mbit doing the initial backup. Thats something that Crashplan only very rarely managed.

    Thanks for all your hard work in getting this working over the years.

    I’m trying to revive my DS212+ and CrashPlan, but the package isn’t showing up the community section of packages. I’ve got DSM 6.1-15047, with a MARVELL Kirkwood 88F6282 CPU.

    Am I just out of luck? Any chance this set up will work in the future?

    Reply
      1. David Shutt

        Is Crashplan & hence patters no longer supporting any marvell cpus?
        Just bought a DS216j to replace a long time broken DS212j & the package no longer appears to be available :-)

      2. patters Post author

        Unfortunately that is indeed the case. They introduced some proprietary binaries a while back which has limited CrashPlan to Intel CPUs only.

    Just want to know CP whether it can support multiple client to be backup at the same time, or just one client at a time?!

    First, thanks for creating this. Long time user of Crashplan who moved to NAS after media server PC died.

    I have the ds216play with Monaco CPU. It doesn’t appear you have a version for that architecture. Any chance of adding support for it?

    Upgrade was downloaded 24th April. Several start attempts have all failed to get it running, but I haven’t the time at the moment to investigate further.

        Just disable Crashplan updates. Search in here for steps and wait for patters to update the package. Or look for another solution. Which is what I’m doing. Once my Crashplan subscription expires I’m moving to HyperBackup locally and then sync to OneDrive. I happen to have unlimited OneDeive.
        Hope this helps.

      Seems to have been a lack of cpio again.

      1. copied cpio to /usr/bin
      2. Uninstalled
      3. Reinstalled
      4. Restarted
      4. Connected client and logged in

      Now running 4.8.2, synchronising to CP Central and my laptop is backing up to the NAS.

      1. Olivero

        That worked for me – Thanks a lot. Thought I have to give up as well.
        1. copied cpio to /usr/bin (sudo cp /volume1/@appstore/CrashPlan/bin/cpio /usr/bin)
        2. Uninstalled
        3. Reinstalled – with using Java 8 from system (not dedicated)
        4. Restarted CrashPlan app , got error ..package manager…
        5. Rebooted Synology
        6. Restarted CrashPlan App – this time it kept running
        7. Connected client and logged in (scanning now)

      2. shivasprogeny

        That worked for me. For anyone else, I ran sudo cp /var/packages/CrashPlan/target/bin/cpio /usr/bin/cpio

        Martin…you are a genius! I’ve been banging my head against the wall for hours! Copying cpio into /usr/bin did the trick. THANK YOU!

      Me too. Have tried reinstalling, but then crash plan tries to upgrade and then it gets stuck and won’t run. I noticed too that the client software on my mac is running 4.8.2, is this part of the problem?

    1. Hal Sandick

      okay i tried this a few times and it did not work.

      – I then uninstalled crashplan and installed java 8 (instead of using the dedicated java).-
      – I installed crashplan and used default system java. it ran and then stopped — same issue as above:
      I 04/26/17 06:44AM CrashPlan stopped, version 4.8.0, GUID [removed]
      I 04/26/17 06:45AM Synology extracting upgrade from
      /var/packages/CrashPlan/target/upgrade/1436674800482 4.jar
      – i got the authentication token,
      – I restarted NAS
      – manually started crashplan and it is working (scanning for synchronization)

      Go figure

    Had the same issue as people above, failed upgrade to latest version. The usual workarounds (cpio, java update, etc) did not work on their own….
    -Uninstall crashplan
    -Reboot nas
    -upgrade java 7 and 8
    -Reboot nas
    -Reinstall crashplan, with system java
    -Copy new token token to GUI on pc
    -Stop/start service, wait 10m
    -updated succeeded
    -login with gui, enter crashplan credentials
    -import previous backup
    ->Done.

    Ofcourse no guarantee on success…

    Had same problem (1436674800482).
    Got it fixed with cpio post from @Martin. Adding /bin/cpio fixed mine.

    Details of what I did:

    1) cp /volume1/@appstore/CrashPlan/bin/cpio /bin/cpio
    (though could do that after install if not starting service right after install)
    2) DSM CrashPlan Uninstall
    3) DSM CrashPlan Install (Default dedicated Java 8. Do not run after install)
    (/bin/cpio is in place right?)
    4) DSM CrashPlan Action->Run
    5) tail -f /var/packages/CrashPlan/target/log/service.log.0
    (Leave that tail running)
    6) Wait ~1min for: Waiting 60 seconds for upgrade script to shutdown service…
    7) Wait ~1min for: Service stopped normally
    8) DSM CrashPlan Action->Run, receive: “Failed to run the package service”
    9) Wait ~1min for: Enough time to do a good luck dance.
    10) DSM CrashPlan Action->Run
    11) Watch tail produce lots of output (including various warnings)
    12) Fix CrashPlan UI token
    echo `cat /var/lib/crashplan/.ui_info`
    (on client) vi /cygdrive/c/ProgramData/Crashplan/.ui_info
    13) Reconnect CrashPlan
    Start CrashPlan UI
    client: Existing Account
    Provide archive key, save
    Let scan for long time.

      That all looks very promising, and thank you, but I can’t get past the first line…. the response is: cp /volume1/@appstore/CrashPlan/bin/cpio /bin/cpio

        As I thought… being daft. I needed to put ‘sudo’ in front of the instruction. All working fine now. Thank you very much indeed!

        sudo cp /volume1/@appstore/CrashPlan/bin/cpio /bin/cpio

    2. SJL

      aadhoc78 and Martin: Thank you. I was able to upgrade and restart with aadhoc78’s detailed instructions. Somewhere during this process (before I found your instructions), I apparently caused the GUID to be changed, and I was not offered the “adopt” option. So, at the end, I needed to reconnect to my existing backup by issuing the “GUID xxxxxxxxxxxxxx” command from the console specifying the old GUID (found on CrashPlan Central).

      Uhmm try several time you steps, but I guess, I’m not dancing correctly, I can’t get it to passed 9… I get no log no matter how many time I try to run the package and/or repeat the steps.

      Followed these instructions and version 4.8.3 is now working.

      NOTE: “ls /bin/cpio” showed me immediately that cpio was missing. Also remember to be root through the instructions.

    Hi – I am about 81% backed up but my Crashplan has stopped. I have a DS416play so I think its still supported as it has an intel architecture. I have updated my DSM but Crashplan is still stopped and not showing an update button either. Can someone assist?

    So I just upgraded to 4.8.0-0044 and now the app refuses to save my encryption key. It says “Preferences saved by the user.” and promptly reverts back to the way it was. Has anyone else seen this problem? Any suggestions? Thanks!

    addhoc78, can you explain just little more for us novices steps 1, 5, and 12. I don’t quite understand those steps and what we are supposed to do there. My crashplan has been offline for almost a week now. Come October when my subscription runs out I too am switching over to HyperBackup and the unlimited plan that Amazon Drive has for the same price as CP’s unlimited. These constant band-aides over and over again are really a pain and there’s no sign Synology will ever support CP on their devices.

    I’m not a script wiz, but it seems that maybe someone should write one for the updates using the steps that aadhoc78 did. That way, the future updates could easily be taken care of instead of loading patters install for each version that comes out. Thinking wrong here?

    Reply
    1. aadhoc78

      I’m not sure how @patters expects cpio, or where it comes from. The script did seem to look a few places for it before giving up. I suspect @patters will merely ensure that cpio is right and his script will be good again. His script deserves a lot of credit. I don’t know where most of his details & files come from.

      You skipped the good luck dance, didn’t you.

      My issue seemed to be that cpio missing. I don’t know if there are other issues. BTW, I did the uninstall/reinstall several times before I got that combination to work (I didn’t see any harm in doing it a few times). If you do what I did (verifying that /bin/cpio is there before the install), then there’s a good chance it will work, but maybe you’ve got a different issue?!?

      Reply
      1. BriGuy1

        I’m missing the CPIO also. How did you get it in there? I tried to uninstall/reinstall a few times without success.

        Otherwise I was able to follow your steps without issue. Just can’t copy CPIO, seems to be my issue

      2. Bryan W

        This may be a dumb question, bur how do you verify that the directory is there? I am having the same issue where the service does not start back up at Step 10.

    2. ilkevinli

      I had the same problem. The issue was I had to set the file properties for the cpio file in /usr/bin to be 0777 (rwrwrwrw). Once I did that, it worked.
