CrashPlan packages for Synology NAS

UPDATE – The instructions and notes on this page apply to all three versions of the package hosted on my repo: CrashPlan, CrashPlan PRO, and CrashPlan PROe.

CrashPlan is a popular online backup solution which supports continuous syncing. With this your NAS can become even more resilient – it could even get stolen or destroyed and you would still have your data. Whilst you can pay a small monthly charge for a storage allocation in the Cloud, one neat feature CrashPlan offers is for individuals to collaboratively backup their important data to each other – for free! You could install CrashPlan on your laptop and have it continuously protecting your documents to your NAS, even whilst away from home.

CrashPlan-Windows

CrashPlan is a Java application, and 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 a few others. As I started I used information from Kenneth Larsen’s blog post, the Vincesoft blog article for installing on ARM processor Iomega NAS units, and this handy PDF document which is a digest of all of them. I used the PowerPC binaries Christophe had compiled on his chreggy.fr blog, so thanks go to him. I wanted make sure the package didn’t require the NAS to be bootstrapped, so I bundled any dependent binaries. Back in 2012 I didn’t know how to cross compile properly so I had to use versions I had found, but over the years I have had to compile my own versions of many of these binaries, especially as I added support for Synology’s huge proliferation of different CPU architectures.

UPDATE – For version 3.2 I also had to identify and then figure out how to compile Tim Macinta’s fast MD5 library, to fix the supplied libmd5.so on ARM systems (CrashPlan only distributes libraries for x86). I’m documenting that process here in case more libs are required in future versions. I identified it from the error message in log/engine_error.log and by running objdump -x libmd5.so. I could see that the same Java_com_twmacinta_util_MD5_Transform_1native function mentioned in the error was present in the x86 lib but not in my compiled libmd5.so from W3C Libwww. I took the headers from an install of OpenJDK on a regular Ubuntu desktop. I then used the Linux x86 source from the download bundle on Tim’s website – the closest match – and compiled it directly on the syno using the command line from a comment in another version of that source:
gcc -O3 -shared -I/tmp/jdk_headers/include /tmp/fast-md5/src/lib/arch/linux_x86/MD5.c -o libmd5.so

Licence compliance is another challenge – Code 42 Software’s EULA prohibits redistribution of their work. I had to make the syno package download CrashPlan for Linux (after the end user agrees their EULA), then I had to write my own script to extract this archive and mimic their installer, since their installer is interactive

 

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
  • Since CrashPlan is a Java application, you will need to install one of my Java SE Embedded packages first (Java 7 or 8) if you have not already done so. Read the instructions on that page carefully too.
  • Now browse the Community section in Package Center to install CrashPlan. 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.
  • CrashPlan is installed in headless mode – backup engine only. This is 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.
  • If you previously installed CrashPlan manually using the Synology Wiki, you can find uninstall instructions here.
 

CrashPlan Client Installation

  • Once the engine is running, you can manage it by installing CrashPlan on another computer, and by configuring it to connect to the NAS instance of the CrashPlan Engine.
  • To do this you need to edit the file conf/ui.properties in the CrashPlan folder on that computer so that this line:
    #serviceHost=127.0.0.1
    is uncommented (by removing the hash symbol) and set to the IP address of your NAS, e.g.:
    serviceHost=192.168.1.210
    Mac OS X users can edit this file from the Terminal using:
    sudo nano /Applications/CrashPlan.app/Contents/Resources/Java/conf/ui.properties
    (use Ctrl-X to save changes and exit)
  • Starting with CrashPlan version 4.3.0 you will also need to 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 followed by a GUID:
    4243,9ac9b642-ba26-4578-b705-124c6efc920b
    Copy this GUID and use this value to replace the GUID in the equivalent file on the computer you want to run the CrashPlan client on:
    C:\ProgramData\CrashPlan\.ui_info (Windows)
    /Library/Application Support/CrashPlan/.ui_info (Mac OS X)
    /var/lib/crashplan/.ui_info (Linux)
    You will not be able to connect the client unless these GUIDs match on the NAS and the client. If it still won’t connect, check that the ServicePort value is set to 4243 in the following file:
    C:\ProgramData\CrashPlan\conf\ui_(username).properties
  • 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) 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 cp /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

 

Notes

  • The package downloads the CrashPlan installer directly from Code 42 Software, following acceptance of their EULA. I am complying with their wish that no one redistributes it.
  • Real-time backup does not work on PowerPC systems for some unknown reason, despite many attempts to cross compile libjna, and attempts to use binaries taken from various Debian distros (methods that work for the other supported CPU architectures).
  • 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. 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 sets which are scheduled to be protected at different times
  • The default location for saving friends’ backups is set to /volume1/crashplan/backupArchives (where /volume1 is you primary storage volume) to eliminate the chance of them being destroyed accidentally by uninstalling the package.
  • 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
    This is particularly useful on ARM systems because CrashPlan currently prevents hibernation while it is running (unresolved issue, reported to Code 42). 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

  • 0031 Updated to CrashPlan 4.2, cross compiled a newer cpio binary for some architectures which were segfaulting while unpacking main CrashPlan archive, added port 4242 to the firewall definition (friend backups), package is now signed with repository private key
  • 0030 Fixed show-stopping issue with version 0029 for systems with more than one volume
  • 0029 Updated to CrashPlan version 3.7.0, improved detection of temp folder (prevent use of /var/@tmp), added support for Annapurna Alpine AL514 CPU (armhf) in DS2015xs, added support for Marvell Armada 375 CPU (armhf) in DS215j, abandoned practical efforts to try to support Code42’s upgrade scripts, abandoned inotify support (realtime backup) on PowerPC after many failed attempts with self-built and pre-built jtux and jna libraries, back-merged older libffi support for old PowerPC binaries after it was removed in 0028 re-write
  • 0028 Substantial re-write:
    Updated to CrashPlan version 3.6.4
    DSM 5.0 or newer is now required
    libjnidispatch.so taken from Debian JNA 3.2.7 package with dependency on newer libffi.so.6 (included in DSM 5.0)
    jna-3.2.5.jar emptied of irrelevant CPU architecture libs to reduce size
    Increased default max heap size from 512MB to 1GB on systems with more than 1GB RAM
    Intel CPUs no longer need the awkward glibc version-faking shim to enable inotify support (for real-time backup)
    Switched to using root account – no more adding account permissions for backup, package upgrades will no longer break this
    DSM Firewall application definition added
    Tested with DSM Task Scheduler to allow backups between certain times of day only, saving RAM when not in use
    Daemon init script now uses a proper PID file instead of Code42’s unreliable method of using grep on the output of ps
    Daemon init script can be run from the command line
    Removal of bash binary dependency now Code42’s CrashPlanEngine script is no longer used
    Removal of nice binary dependency, using BusyBox equivalent renice

  • 0027 Fixed open file handle limit for very large backup sets (ulimit fix)
  • 0026 Updated all CrashPlan clients to version 3.6.3, improved handling of Java temp files
  • 0025 glibc version shim no longer used on Intel Synology models running DSM 5.0
  • 0024 Updated to CrashPlan PROe 3.6.1.4 and added support for PowerPC 2010 Synology models running DSM 5.0
  • 0023 Added support for Intel Atom Evansport and Armada XP CPUs in new DSx14 products
  • 0022 Updated all CrashPlan client versions to 3.5.3, compiled native binary dependencies to add support for Armada 370 CPU (DS213j), start-stop-status.sh now updates the new javaMemoryHeapMax value in my.service.xml to the value defined in syno_package.vars
  • 0021 Updated CrashPlan to version 3.5.2
  • 0020 Fixes for DSM 4.2
  • 018 Updated CrashPlan PRO to version 3.4.1
  • 017 Updated CrashPlan and CrashPlan PROe to version 3.4.1, and improved in-app update handling
  • 016 Added support for Freescale QorIQ CPUs in some x13 series Synology models, and installer script now downloads native binaries separately to reduce repo hosting bandwidth, PowerQUICC PowerPC processors in previous Synology generations with older glibc versions are not supported
  • 015 Added support for easy scheduling via cron – see updated Notes section
  • 014 DSM 4.1 user profile permissions fix
  • 013 implemented update handling for future automatic updates from Code 42, and incremented CrashPlanPRO client to release version 3.2.1
  • 012 incremented CrashPlanPROe client to release version 3.3
  • 011 minor fix to allow a wildcard on the cpio archive name inside the main installer package (to fix CP PROe client since Code 42 Software had amended the cpio file version to 3.2.1.2)
  • 010 minor bug fix relating to daemon home directory path
  • 009 rewrote the scripts to be even easier to maintain and unified as much as possible with my imminent CrashPlan PROe server package, fixed a timezone bug (tightened regex matching), moved the script-amending logic from installer.sh to start-stop-status.sh with it now applying to all .sh scripts each startup so perhaps updates from Code42 might work in future, if wget fails to fetch the installer from Code42 the installer will look for the file in the public shared folder
  • 008 merged the 14 package scripts each (7 for ARM, 7 for Intel) for CP, CP PRO, & CP PROe – 42 scripts in total – down to just two! ARM & Intel are now supported by the same package, Intel synos now have working inotify support (Real-Time Backup) thanks to rwojo’s shim to pass the glibc version check, upgrade process now retains login, cache and log data (no more re-scanning), users can specify a persistent larger max heap size for very large backup sets
  • 007 fixed a bug that broke CrashPlan if the Java folder moved (if you changed version)
  • 006 installation now fails without User Home service enabled, fixed Daylight Saving Time support, automated replacing the ARM libffi.so symlink which is destroyed by DSM upgrades, stopped assuming the primary storage volume is /volume1, reset ownership on /var/lib/crashplan and the Friends backup location after installs and upgrades
  • 005 added warning to restart daemon after 1st run, and improved upgrade process again
  • 004 updated to CrashPlan 3.2.1 and improved package upgrade process, forced binding to 0.0.0.0 each startup
  • 003 fixed ownership of /volume1/crashplan folder
  • 002 updated to CrashPlan 3.2
  • 001 intial public release

    I seem to have the backup up working again, but the crash plan tray icon is greyed out and states “waiting for login”. When I click on the icon it opens correctly and everything seems to be working correctly. Does anybody know if this is a problem? Thanks

      The tray icon is probably reporting on the status of the CrashPlan engine instance that’s running on your computer. You can disable that completely if you want. See the main post Client Installation section for details how.

    Thanks, I have just noticed (your very small) paypal button so I have made a small donation for all your hard work & support.

      copy it from the nas /var/lib/Crashplan/.ui_info to c:\Documents and Settings\All User\Application Data\Crashplan

        Hi,

        The .ui_info should copy to “C:\Documents and Settings\All User\Application Data\Crashplan” or ” “C:\ProgramData\CrashPlan”?

    Hi,

    recently got hands on a friends DS215+ and noticed due to the new CPU the architecture naming got extended to “alpine4k” for this model, so you’re packages won’t be listed in the package center.

    Any plans to make ’em compatible to this new(upgraded) arch? Very happy to serve as a guinea pig ;-)

        First step – can you try to install the Java 8 package? I just updated it to support alpine4k. Once it’s installed can you look in the Java package log in Package Center and check that it reports the HotSpot version like this:
        java version “1.8.0_51”
        Java(TM) SE Embedded Runtime Environment (build 1.8.0_51-b07, headless)
        Java HotSpot(TM) Embedded Client VM (build 25.51-b07, mixed mode)

      2. patters Post author

        Sorry – although I added support to the package, I forgot to update the supported architectures on the repo. It’s fixed now. Let me know if it works and whether you can run:
        java -version

        Can you also run:
        uname -a

      3. Loïc (@loakus)

        Thanks.

        output:

        Great! Can you also run:
        cat /proc/cpuinfo

        Then after that please can you try the following:
        cd /volume1/@tmp
        mkdir ffmpeg
        cd ffmpeg
        wget http://packages.pcloadletter.co.uk/downloads/serviio1.5-native-armhfneon.tar.xz
        tar xvJf serviio1.5-native-armhfneon.tar.xz
        ./ffmpeg
        ldd ./ffmpeg

        This will tell me whether code built with the alpine toolchain is also ok for alpine4k (since there is not yet a Synology distributed toolchain).

    I had posted an issue with CrashPlan on synology failing to start recently. I just applied the 4.3.0-0033 update that popped up on my friends Synology and the unit now connects to my file server and is backing up! Thanks to the devs for this awesome app (and automatic fix)!

        I do not see my Synology files from the CrashPlan client anymore and therefore I can’t configure backup to the Cloud. It seems that CrashPlan guys changed something in the recent release in the way that some of the technical files are missing or misplaced. As a result no internet instructions “How to” are useful anymore…

      2. Jake

        I’m in the same boat here as well. Even booted up another Windows instance to make sure it wasn’t something wrong there. I can’t see my NAS unit anymore even though the ssh tunnel is active and the .ui_conf file is adjusted.

  5. Eric

    My crashplan instance is stuck at “Waiting for backup”. I tried contacting support but they didn’t have any suggestions since this isn’t an an offically supported configuration. Any tips to debug and resolve? I tried to SSH but I don’t know what where all the logs are and what’s important.

    Hello All…

    I’m about to setup my new NAS to run Crashplan. Would someone please be so kind as to let me know whether it is best to run Java 7 or 8..?

    My older NAS is running Java 7 with no issues.

    Thank you all.

    Hi Patters, i have recently apply the Mac os X El Capitan and in the same time, the DSM 5.2 Update 2 was applied too. the chrisnelson.ca method seems to be not working, but that’s not the truth, the chrisnelson.ca method corrects well and fix the DSM Update damage but in my case my client doesn’t work on my Mac os x client and works fine on my Synology server. This morning a new update for El Capitan has arrived and like a sharm my Crashplan client opens again !. So wait a lot and apply the fix from Mac os X El capitan or … don’t apply this bêta.
    Thank’s a lot for your work Crashplan for Synology is a really good tool.

    Hi Patters,

    just a quick question. Been using your app for a few months and it’s working great. I have 11 different backup sets, each about 300-500 GB.

    Is it a good idea to leave the default scheduling settings for each backup set or could this be optimized? Every backup set has the following options:
    Backup will run: Always
    Verify selection every: 1 days at 03:00

    Is this a good idea? My NAS is online 24/7

    And where are the settings for my backup sets stored? On my client machine or/and on my NAS? Would be a good idea to backup Crashplan as well in case of a disaster!?

    On the DSM 5.2 the crashplan headless client is running. I followed the steps to install the client on windows including copying the guid from the nas to the.ui_info file. The client still hangs when we start it.

    It appears that Code42 have made some more changes over the weekend. On the Windows PC that runs my admin client, I found that ui.properties had been replaced by a new ui_[username].properties, and both it and .ui_info had been reset to defaults. After copying .ui_info from the NAS, and adding serviceHost=ip.address.of.nas back into ui_[username].properties, the local client was able to resume connection to the headless client on the NAS.

    Oh, and while I’m here, I noticed that the NAS client is timestamping everything one hour in the past – it appears that whatever DST bug was previously fixed, has regressed.

    Hi,

    I successfully migrated a Crashplan setup from an old DS213+ to a new DS715 with all backup sets intact. Crashplan, Java package and the headless setup (on a Windows 10 PC) worked without any issues. It was just to follow all the instructions.

    Thx Patters for your work making this easy. A small donation is coming your way too.

    Good day,

    I have instaled Crashplan on a Synology DS 1815+. Everything worked fine until the update. Now ich cannot connect the headless client from my computer. I’ve copied the ui-properties but this doesn’t work either.

    What can I do to connect again?

    I’m finding lately that my .ui_info file occasionally updates itself to some random GUID and I can no longer get the UI to open. Then I have to “fight” with CrashPlan to get it to accept the GUID that I put in. I have no idea why it keeps changing itself.

      Could it be that the CrashPlan service is running on your PC, which isn’t needed if you only use the client to access your NAS instance. Perhaps the service occasionally installs an update which pushes the PC’s GUID back into that config file.

      Reply
      1. B. Goodman

        Well, I do use the client on the PC as well, so I’d prefer not to disable the service. As for the service, occasionally installing an update, I cannot say, but I do know that I changed it 3 times in a 5 minute span this morning trying to get it to connect to the Synology. Finally, I changed it and set the “read-only” file attribute in the hope that it wouldn’t get replaced. So far, it’s stayed correct for almost 3 hours now, but I don’t know if that change might cause problems later.

    Does anybody know what the maximum usable USR_MAX_HEAP setting is? I’ve tried setting mine to 8192M (of 16GB of RAM on my 1815+), but CrashPlan won’t even start. 4096M seems to have the same problem.

        From the instructions at the top of this thread.

        Starting with CrashPlan version 4.3.0 you will also need to run this command on your NAS from an SSH session:
        echo `cat /var/lib/crashplan/.ui_info`

    Hi Patters,
    I succesfully installed the 4.3.0 and I can connect to the nas but I cannot login in to the cloud.
    When I open the client and I insert username and password I receive the message “Unable to connect, check your network”.
    The firewall rules on NAS are ok, the firewall rules on router are ok…the nas can succesfully connect to internet (in fact I installed your new vesion).
    Please help me because are 7 months that I cannot make a backup on cloud.
    What can I check? What log can I read to undestand why it doesn’t connect?

    Thank you

    Hi Patters,
    I have a Ds412+ and have been running Crashplan for a couple years. I have uploaded almost 6 TB with another TB to go. After uninstalling CrashPlan and Java, I rebooted and then reinstalled the apps following the instructions above. About every hour of the day, it says CrashPlan started, version 4.3.0, GUID 54____________, Then it says Starting backup to Crashplan Central 1,085 files (673.12GB) to back up, Then an hour later it says Stopping Crashplan. It does this every day. I updated syno_package.vars to have a max of 2056. That is the maximum of my NAS. Can I increase the memory to an amount larger than what I have installed? Should I resort to different Backup Sets?

    1. Sam

      Hi Michael, I have the same problem, but haven’t even got as far as you, yet. How do I increase the heap to 2056 or greater. I am using a Mac to run ‘headlessly’ my NAS. Is that the same for you? Do I use Terminal? What do I type in? Any help appreciated.

      Reply
      1. Michael

        Hi Sam, I am running CrashPlan headlesslly on my Synology drive. To change the heap size, open a Mac Terminal and type in SSH root@192.168.X.X where the ip address is the ip address of your NAS drive and the password for root is the same as the password for your admin account on the drive. That will put you at the terminal on the NAS. Type in VI /volume1/@appstore/CrashPlan/syno_package.vars and remove the # in front of #USR_MAX_HEAP=XXXX and making XXXX=1536
        If you aren’t familiar with the VI editor, open a web browser and google VI COMMANDS to help. Once done, you restart the application in package manager on DSM.

    Hi Patters
    My crashplan stopped working a while back.
    I have upgraded the Java package and clicked the crashplan install (there is no upgrade option).
    the app goes through the process correctly downloads the latest package and then runs literally for 30 minutes or longer. Eventually it comes back with “failed to instal” message. On the action back it has the status “installing”. I have to reboot the DS414j to get rid of “installing”.
    What am i doing wrong?

      Seems like the port changes to 14243 after restart and there after I am not able to connect.

      Have tried editing the port in my.service.xml but it gets changed back after restart as well.

      Backups seem to be running fine according to the log. But as of now the only way I can gain connection to the headless install is:

      – Uninstall
      – Install clean
      – Copy the ui_info files
      – Update the ui.properties to connect to the NAS

      Make changes restores etc.

      But as soon as the NAS has been rebooted or the service restarted ui_info and my.service.xml changes port to 14243 and connection is not possible.

      Anyone else with similar problem?

    I have been running Crashplan on a Synology Diskstation DS415+ for a few months.
    After the latest upgrade it stopped working. I have uninstalled crashplan, uninstalled Java and reinstalled everything according to the instructions above.

    The client can connect to the service, but nothing is being backed up. The history.log.0 contains pages and pages of restart information, see below.

    What can I do to try to remedy the problem?

      It’s running out of memory. Increase the JAVA heap size as described earlier in the support thread.

        It works now. 1GB was not enough (it kept crashing) but 1.5GB works. My backup set i 2.6TB.

        I took the plunge and upgraded the RAM in the DS415+ from 2 to 8GB and now I have allocated 3GB to Java. This should work for some time.

        Thanks again.

    I recently upgraded the RAM in my DS415+ and am trying to figure out the maximum java heap size. 2GB is too small for my backup sets, 4GB doesn’t work at all, 3GB seems to work well. Is there a way to determine the maximum heap size that can be allocated? Anyone know why 4GB doesn’t work?

    Thanks in advance.

      No idea, I tried 4096M too but it just doesn’t want to accept it (maybe something to do with 32bit max memory? I don’t know). But I’ve found that 2048M works well even for a 10TB+ backup (although I settled for 3072M because I can spare it).

    Great work :-) … I got a bit inspired, and am trying to compile some packages for some NAS boxes in friends locations, and speculate whether you can tell me if there is any working SPK repository server code somewhere? I have been looking at sspks at github, but it is not working with the most current DSM builds (even though I have tried to patch the JSON returned to the DSM box). Will you be able to give me some input ? Send me an email if you can spend a bit of time helping…

      I used Wireshark to sniff the HTTP GET request that the syno makes and used curl to reproduce that on the command line. Then you can see precisely how the official repo responds. With each DSM it gets slightly more complicated. Not near a PC right now.

        As far as I can see, the package list comes out of a POST request – which returns some JSON data. Even though I managed to reconstruct the JSON data structure, it apparently isn’t enough…

      2. bipsen

        It now seems to work – almost… Except for the displayed icon for my package in package manager, under “Community” .. I have a thumbnails section in the json output, and also package_icon variable in the INFO file… Any inpu on why the right icon not is displayed? It seems like the NAS never requests the image from the web server…
