To upgrade your Code42 environment, see our upgrade instructions.


Refreshed, Modern CrashPlan User Interface

Version 5.0 of the Code42 CrashPlan app simplifies life for administrators and users with an overhauled user interface which makes it even easier to manage and use CrashPlan for backup and recovery. See Changes To The Code42 CrashPlan App In Version 5.0.1 for complete details.

Code42 CrashPlan App Version 5.0.1

Windows User Profile Backup

The Code42 platform now supports user profile backup and integration with Microsoft's User State Migration Tool (USMT). User profile backup makes it easy to use CrashPlan to migrate system settings and application data to a new or upgraded user device.

Legal Hold

The Code42 Legal Hold web app allows legal teams to easily create and manage legal holds, place users (custodians) in your Code42 environment under a legal hold, and collect data from legal holds. For complete details, see Configuring A Legal Hold.

Code42 platform version 5.0.1 is bundled with both version 4.4.1 and 5.0.1 of the CrashPlan app.

Code42 app version 5.x requires on-premises authority server
In order to upgrade to version 5.x of the Code42 app, you must have an on-premises authority server. If you use the Code42 cloud with hosted keys or CrashPlan for Small Business, then your Code42 apps will upgrade to the most recent version of 4.x instead.

Version 4.4.1

  • Security updates.
  • Performance and stability improvements.
  • The minimum required Java version for the CrashPlan app is now 1.7.
  • Corrects issue introduced in version 4.3 of the Windows CrashPlan app in which the the CrashPlan Tray app (the CrashPlan icon in the notification area) is dimmed and disabled when the CrashPlan app is installed in a folder other than the default location.
  • Improvements to the upgrade process in the OS X CrashPlan app when applying upgrades that span multiple versions.​
  • Improvements to OS X CrashPlan app customization process: customizing the default.service.xml file is now honored by the installer.
  • Corrects rare issue that could prevent a user with two different computers backing up to a provider storage destination from being able to restore files from one computer to the other.

  • Improved error messaging if the localhost entries in a device's hosts file do not point to the default loopback IP addresses.
  • Corrects issue in which some customized CrashPlan app installers allowed the user to edit the server address field, even when lockedAddress was set to true.
  • Corrects an issue in which an unmounted Network File System (NFS) on an OS X device could be automatically re-mounted by CrashPlan.
  • The CrashPlan app for OS X now uses a natively precompiled Java service, which does not require the Java Virtual Machine (JVM) to run.
CrashPlan App Modifications Not Supported In Version 5.0.x
If you have modified the CrashPlan app's text or images, these modifications are lost when you upgrade from version 4.x to version 5.0.x of the CrashPlan app.


  • Improves ability to upload very large files via the SharePlan web app.
  • Deactivated SharePlan archives are now visible in Cold Storage.

All storage servers in your Code42 environment must use the same Code42 server software version as your authority server. 

Known Issues

  • If you modified the CrashPlan app's text or images in version 4.2.x or earlier, there is a known issue that causes these modifications to be lost on Windows devices that upgrade to version 4.4.3 of the CrashPlan app. If possible, we recommend waiting to upgrade Windows devices in your Code42 environment until this is corrected in a future release.
  • Backing up to account devices (computer-to-computer backup) is not supported in version 5.0.1 of the CrashPlan app. If you have existing devices with computer-to-computer backups that were configured in version 4.4 or earlier of the CrashPlan app, see Disabling Computer-To-Computer Backup for complete details.
  • If the IP address of a Code42 server changes, entering https://localhost:4285 or http://localhost:4280 in the Code42 server’s web browser no longer redirects to the administration console. To access the administration console, you must enter the full URL, such as https://localhost:4285/console/
  • After upgrading from version 4.x to 5.x of the CrashPlan app, the user must manually sign in the first time the app is opened.
  • On Windows devices, if the CrashPlan app version 5.0.1 is installed per user, launching the CrashPlan app from the CrashPlan tray app may result in an “unable to connect to background service” error message. If this occurs, users can launch the CrashPlan app from the Windows Start Menu.
  • The CrashPlan app version 5.0.1 only supports standard archive encryption. Devices using upgraded security (archive key password or custom key) can only upgrade to version 4.4.1.
  • On Windows devices, if a file is locked and a copy is therefore backed up via VSS, some file metadata may not be backed up.
  • If the CrashPlan app is open when the upgrade to version 4.4.1 happens, the CrashPlan app closes and does not automatically reopen. You must manually reopen the CrashPlan app.
  • Installing per user on a Windows device does not create a CrashPlan app shortcut on the Desktop.
  • The CrashPlan app must be installed in the default location when installing per user on a Windows device.
  • In the CrashPlan app version 5.0, the replace device screen incorrectly displays the same Last Activity time and date for all devices.
  • If an organization contains a colon in its name, administrators cannot view the archives in cold storage for that organization. To view the archives in cold storage, remove all colons from the organization's name (including from the "deactivated" time stamp, if applicable).
