Uninstall the CrashPlan app

Overview

This article explains how to uninstall the CrashPlan app from your computer.

Uninstalling the CrashPlan app removes the log files associated with your backups on this computer. If you're uninstalling as part of a troubleshooting process, send your log files to our technical support team before uninstalling.

Standard uninstall

A standard uninstall removes the CrashPlan app from your computer. An identity file is left on your computer in case you reinstall in the future.

Windows

1. Open the Control Panel and select Uninstall a Program.
2. Select CrashPlan and choose Uninstall.

You may be prompted that another user on the device is signed in. If another user is signed in, it may prevent the CrashPlan app from uninstalling completely. Coordinate with other users to ensure all users are signed out of their accounts before continuing.

Mac

1. Open the Finder.
2. Press Command+Shift+G.
   A dialog box appears: Go to the folder.
3. Paste this text into the dialog box:
   • Installed for everyone: /Library/Application Support/CrashPlan/Uninstall.app
   • Installed per user: ~/Library/Application Support/CrashPlan/Uninstall.app
4. Click Go.
   If you see the error "The folder can't be found", download the CrashPlan Mac installer and continue to the next step. 
5. Double-click Uninstall.
6. Follow the prompts to complete the uninstall process.

Linux

1. Download the CrashPlan app.
2. Uncompress the TGZ file in Downloads.
3. Open Terminal and enter:

   cd ~/Downloads/crashplan-install

4. Press Enter.
5. Then enter: 

   sudo ./uninstall.sh -i /usr/local/crashplan

6. Press Enter.
7. At the prompt, type YES to uninstall and press Enter.

Complete uninstall

A complete uninstall removes the CrashPlan app, your computer's identity file, and any backups on your computer. Only perform a complete uninstall if:

• You want to permanently end all CrashPlan app backups for this computer.
• A technical support agent instructs you to do so.

To completely uninstall the CrashPlan app:

1. Follow the instructions above for a standard uninstall.
2. Delete the following folder from your computer:
   • Windows:
     • If installed for everyone: C:\ProgramData\CrashPlan
     • If installed per user: C:\Users\<username>\AppData\<Local or Roaming>\CrashPlan
   • Mac:
     
     • If installed for everyone: /Library/Application Support/CrashPlan
     • If installed per user: ~/Library/Application Support/CrashPlan
   • Linux: /var/lib/crashplan

Manual uninstall for Mac

Perform the following steps if you were unable to uninstall the CrashPlan app on a Mac using the directions provided above.

A manual uninstall is typically not needed on Windows or Linux. However, if you already tried to remove the CrashPlan app on a Mac by a non-standard method, the normal uninstall process will error out if subsequently run. This is because the installation file is locked on a Mac and it must be unlocked (with a chflags noschg command) before it can be uninstalled.

Installed for all users

1. Run the following command in Terminal:

   sudo ls

2. Enter the administrator password for the computer and press Return. 
3. Copy and paste the following commands.

   sudo launchctl unload /Library/LaunchDaemons/com.crashplan.service.plist
   sudo chflags noschg /Applications/CrashPlan.app
   sudo chmod -R 755 "/Library/Application Support/CrashPlan/"

4. Open a Finder window and delete the following folders:

   /Library/LaunchDaemons/com.crashplan.service.plist
   /Applications/CrashPlan/
   /Library/Caches/CrashPlan/
   /Library/Application Support/CrashPlan/      

   Inside the last folder is a backupArchives directory that may contain inbound backups from another computer. If there is data in this folder, move it elsewhere.

Installed per user

1. Run the following command in Terminal:

   sudo ls

2. Enter the administrator password for the computer and press Return. 
3. Copy and paste the following commands. The "~" symbol designates the user folder.

   sudo launchctl unload ~/Library/LaunchAgents/com.crashplan.service.plist
   sudo chflags noschg ~/Applications/CrashPlan.app
   sudo chmod -R 755 "~/Library/Application Support/CrashPlan/"

4. Open a Finder window and delete the following folder:  ~/Library/Application Support/CrashPlan/
   Inside this folder is a backupArchives directory that may contain inbound backups from another computer. If there is data in this folder, move it elsewhere.

Scripted uninstall for Mac and Windows

To perform an automated manual uninstall on Mac or Windows via script, use the following example scripts provided by our Professional Services team.

Mac

Professional Services filename:  mac_uninstall.sh

# The section below uninstalls CrashPlan, if it is installed on the system.
if [[ -e /Library/Application\ Support/CrashPlan/ ]]; then
    launchctl unload /Library/LaunchDaemons/com.crashplan.engine.plist
    launchctl unload /Library/LaunchDaemons/com.crashplan.service.plist
    /Library/Application\ Support/CrashPlan/Uninstall.app/Contents/Resources/uninstall.sh
fi
# The section below removes the CrashPlan identity file. Uncomment the lines below if you wish to do a complete uninstall.
# rm -r /Library/Application\ Support/CrashPlan/

Windows

Windows Management Instrumentation (WMI) script

Professional Services filename:  win_uninstall_WMI.ps1
