CrashPlan 6.8.8 or later for Linux - Installation

On this page:


  • Install the CrashPlan client for Linux using the customized MIT installer script. Installation will be fully automated.
  • At first launch, use "Sign up for an account," and create a new account using your MIT Kerberos username and password or sign-in with an existing account.
  • Note that even if you plan to run CrashPlan on a headless server, you will need to do this initial log in via the GUI.

Step-by-step Instructions

Please note that the file name you have downloaded may vary based on the version available at the time of download and screen shots may vary slightly in appearance or version number depending on the version you're installing.
  1. Go to the CrashPlan download page on the IS&T Software Grid (Certificates required.)
    Result: The file containing the CrashPlan installer downloads as "Code42CrashPlan_6.8.8_Linux-MIT.tgz".
  2. Using a terminal window, extract the files from the .tgz file. We recommend putting the .tgz and the extracted files into a folder that root can read, such as /tmp:
    user@computer$ mv Code42CrashPlan_6.8.8_Linux-MIT.tgz /tmp
    user@computer$ cd /tmp
    user@computer$ tar zxf Code42CrashPlan_6.8.8_Linux-MIT.tgz

    Result: The Code42CrashPlan_6.8.8_Linux-MIT.tgz archive is expanded and creates a new folder named crashplan-install and an install script called

  3. Run the install script. Enter your password when prompted.
    root@computer# cd crashplan-install
    root@computer# sudo ./
    root@computer# [sudo] password for KerbID:
    Welcome to the Code42 CrashPlan installer.
    Press *enter* to continue with installation.
  4. The installation will proceed fully automated. A message will indicate that the installation is complete.
    Installation is complete. Thank you for installing Code42 CrashPlan.
  5. You can launch the CrashPlan GUI by running /usr/local/bin/CrashPlanDesktop
  6. The CrashPlan Desktop program will open.
    1. If this is your first time using CrashPlan for an MIT computer, choose Sign up for an account, and enter your Kerberos Username and Kerberos Password in the boxes, and click Sign Up.
    2.  Enter the information for your account
    3. If you have used CrashPlan on other MIT computers, choose Existing Account, and enter your Kerberos Username click Continue then enter your Kerberos Password and click Continue.

      Note: If you are asked for a server address or certificate, see CrashPlan is asking me for a server address and registration key
    4. You will have to choose whether the computer is setup as new device or to replace any existing device. The CrashPlan wizard will walk you through each scenario.
    5. You will now be at the CrashPlan Desktop main screen and your computer should begin to backup.
  • If you have many large files, first time backup may take a few days but subsequent backups should be quicker.
  • CrashPlan selects every "User" folder on your computer. It also selects some hidden folders; it is normal to see a half-dozen folders on the list, including ones that you haven't seen before.
  • Because CrashPlan is always working to keep your computer backed up, you may want to pause backups while you are away from campus to avoid using up your personal data limits or incurring any extra fees for overages. To pause CrashPlan's backups, simply click the pause button next to the status bar per the image above. Just be sure to turn it back on later!
