Headless crashplan how to#There is a relatively detailed set of guidelines how to do this on the CrashPlan site. The detailed instructions how to do this vary, depending on the operating system on your client computer. In order to connect the CrashPlan Desktop from your client computer to the headless engine running on your B3, you'll have to set up an SSH tunnel with port forwarding on your client computer. In order to do this, you'll have to make some changes to the CrashPlan launcher script:Ĭode: Select all $ /opt/crashplan/bin/CrashPlanEngine start Headless crashplan install#Install the Debian version of JNA, and tell CrashPlan where to find it. For this, CrashPlan includes a precompiled Intel version of libjtux, which of course is useless on the ARM architecture of our B3. ![]() In particular, it makes use of the Java-to-Unix library (libjtux) via an interface known as Java Native Access (JNA). The problem is that CrashPlan still assumes that it is running on an Intel-compatible machine. We will change this later.Īfter installing, CrashPlan will tell you that it has already been launched, but in reality it hasn't.Īt this point CrashPlan will not work yet. Headless crashplan full#CrashPlan needs to be able to do continuous monitoring of file changes in order to do incremental backups, and since full backup sets can easily run to hundreds of thousands of files, the default value of 8192 is indeed often insufficient. The installer will probably also tell you that your inotify limit (the number of files that your Linux kernel can simultaneously watch for changes) is set rather low. In my case, I only have data stored under one user account on the B3 anyway, so I simply install CrashPlan under that user account.Ĭode: Select all $ sudo mkdir /opt/crashplan Headless crashplan software#Running CrashPlan as root is somewhat more convenient in that root can read everything by default, but it also means that you trust a third party binary blob piece of software to do basically anything it wants on your server. If you run CrashPlan under some user account other than root, it will obviously be able to backup only those files that are readable by this user so if you have multiple users on your B3 and want all their data backed up separately, you'll have to create an extra "backup" user and think up a permissions scheme that will allow the backup user to see the data of everybody else, while still hiding their data from each other. The choice you have to make at this point is whether you want to install and run CrashPlan as root or under some other user account. You can find out what the latest version is by looking at the CrashPlan download site. It is sufficient to do this once, CrashPlan will autoupdate itself. Downloading and installing CrashPlanĭownload the Linux installation version for CrashPlan. Since our B3 is a headless server, it is sufficient to install the headless version of the OpenJDK JRE.Ĭode: Select all $ sudo apt-get install openjdk-6-jre-headless 1. On our B3 with its ARM processor architecture, we cannot use the original Sun JRE, so we will use OpenJDK instead. Prerequisites: Installing the Java runtime environmentĬrashPlan is a Java application, so we need to install the Java runtime environment (JRE). This guide uses information from some other sources, including here and here.Ġ. So here's how to get the Java client running on the B3 for automatic backups. Headless crashplan Pc#The nifty thing about the client software is that you can run it in headless mode on a headless server (such as a B3), and run the client portion on another PC with an encrypted connection to the headless server via a SSH tunnel. CrashPlan uses its own client software written in Java. It runs continuously, monitoring files for changes and making continuous incremental backups that are encrypted and stored on CrashPlan's servers. I use this to have my B3 make automated backups.ĬrashPlan ( ) is a service for backing up data to the cloud. ![]() Here's a little installation guide for the CrashPlan backup software. ![]()
