CrashPlan PROe Server package for Synology NAS

CrashPlan is a popular online backup solution, with most people using it to protect their data in the Cloud. However, by licensing CrashPlan PROe server you can be that Cloud and act as the storage provider for other client machines running CrashPlan PROe.

I was recently contracted to implement this on Synology hardware for North Bay Technologies, an IT services company in San Francisco. Instead of undertaking a careful manual install that would be difficult to maintain in future, I decided to go one better – to build a package which integrates properly with Synology DSM. I then back-merged most of the changes into the existing CrashPlan client package scripts so everything is as consistent as possible. It was agreed that I would also publish this to the community, so here it is!

CrashPlan-PROe-dashboard

I should stress at this point that although this package could technically install on Synology products with ARM or QorIQ processors, you should only use this on a model with an Intel CPU. Ideally you should equip it with more than 1GB of RAM too, because the application requires 1GB all for itself. The package repo will not advertise it to ARM systems, because they have far too little available RAM.

As with the CrashPlan client packages I have made, I have been careful to comply with Code 42 Software’s stipulation that no one redistributes their work.

Installation

  • This package is for Intel CPUs only. It will work on an unmodified NAS, no hacking or bootstrapping required.
  • More than 1GB of RAM is recommended.
  • You will need to install my Java SE for Embedded package first. Read the instructions on that page carefully too.
  • In the User Control Panel in DSM, enable the User Homes service.
  • Purchase your Master License Key and licences (or obtain a trial key) from crashplan.com, download the PROe Server installer for Linux, and save in the public shared folder on your NAS. You should have created this folder when you installed the Java package.
  • Install the CrashPlan PROe server Synology package directly from Package Center in DSM. In Settings -> Package Sources add my package repository URL which is http://packages.pcloadletter.co.uk.
 

Notes

  • The package expects the end user to have separately downloaded the CrashPlan PROe Server installer for Linux, and it presents them with the official EULA during installation.
  • For details of TCP ports used, to help you set up firewalling and/or port forwarding please consult the requirements document.
  • Once running, CrashPlan PROe server is configured by a web dashboard on https://yourNasIP:4285/console/ This link can be found in the package info screen in Package Center in Synology DSM when the package is running.
  • Full support documentation is available here.
  • The DSM Package Center upgrade functionality allows you to move between my package versions without losing settings or data, but if you’re moving to a new CrashPlan PROe Server version you will need to do that manually via the admin web app, using the Linux downloads (with file extension .upgrade) available from Code 42 Software. Depending on how up to date your version is, you may need to update incrementally through several versions. Before you apply a Code 42 update package, you should manually install the latest Synology package for the specific PROe Server version you’re currently runnning. This will ensure the update scripts are handled correctly. So for example if you’re upgrading from 3.5.4 to 3.5.5 you should manually install cpproeserver3.5.4-merged-020.spk over the top first. You can find up to date package versions for each PROe Server build here:
    cpproeserver3.2.1.2-merged-0020.spk
    cpproeserver3.3.0.2-merged-0020.spk
    cpproeserver3.3.0.3-merged-0020.spk
    cpproeserver3.3.0.4-merged-0020.spk
    cpproeserver3.4.1-merged-0020.spk
    cpproeserver3.4.1.5-merged-0020.spk
    cpproeserver3.5.1.1-merged-0020.spk
    cpproeserver3.5.3.2-merged-0020.spk
    cpproeserver3.5.4-merged-0020.spk
    cpproeserver3.5.5-merged-0020.spk
  • The engine daemon script checks the amount of system RAM and scales the Java heap size appropriately (up to the default maximum of 1024MB). This can be overridden in a persistent way if you are backing up very large backup sets by editing /volume1/@appstore/cpproeserver/syno_package.vars.
  • As with my other syno packages, this user account password is randomized when it is created using a perl script called passgen (I followed the example of the Transmission package). DSM Package Center runs as the root user so my script starts the package using an su command. This means that you can change the password yourself and CrashPlan will still work.
  • The default location for saving backup data is set to /volume1/cpproeserver (where /volume1 is you primary storage volume) to eliminate the chance of them being destroyed accidentally by uninstalling the package.
  • The package supports upgrading to future versions while preserving the machine identity, logs, login details, and cache.
  • The log which is displayed in the package’s Log tab is actually the activity history. If you’re trying to troubleshoot an issue you may need to use an SSH session to inspect the more detailed log files which are stored in /volume1/cpproeserver/log
  • I’m not sure if it works for the PROe products, but I would really appreciate it if you could use this affiliate link when purchasing your licences (you may need to browse to the PROe section of the website using the links in the footer of that page). If this package saves you the several days worth of work I put into making it, please also consider donating using the PayPal button on the right hand side of the page. Thanks!
