Refreshed, Modern CrashPlan User Interface For Linux

Joining the CrashPlan app improvements released for Windows and OS X devices in version 5.0, version 5.1 brings Linux users an overhauled user interface, making it even easier to manage and use CrashPlan for backup and recovery. See Changes To The Code42 CrashPlan App In Version 5.x for complete details.

Schedule-Based Bandwidth Management

New scheduled sending limits allow administrators to specify different data transfer rates for peak and off-peak business hours.

Administration console scheduled sending limits

Enhanced Indexing And File Search

New indexing capabilities and an accompanying File Search web app allow administrators to search a user's backed up files based on file name, file content, and file metadata.

Endpoint Monitoring

Endpoint monitoring leverages the CrashPlan app to monitor user devices for potential security problems or data leaks resulting from removable media, third-party cloud storage apps, unusual restore activity, and more. Administrators can view these events in real-time via the new Security web app.

Code42 Reporting Web App

The Code42 platform now features a Reporting web app, which enables administrators to easily search and view the backup status of users and devices. 

Reporting Web App

Database Sanitization

The Code42 server contains a new command to export a sanitized version of the database, which removes all sensitive information. This enables administrators to quickly and easily provide Code42 Customer Champions data for troubleshooting, without exposing any sensitive or personally-identifiable information. 

Improved Code42 App For Splunk

The Code42 app for Splunk version 2.1 introduces:

  • Support for new features in the Code42 server version 5.1, including file content pattern matching, file upload detection and other endpoint detection events
  • Other enhancements for security and stability

Fixes And Enhancements

Code42 Platform

  • Security updates.
  • Performance and stability improvements.
  • Code42 server version 5.1 does not support SharePlan. Do not upgrade to version 5.1 if you wish to continue using any remaining SharePlan subscriptions. See SharePlan End Of Sale And End Of Support for additional details.
  • The minimum required Java version for the Code42 server is now 1.8.
  • Java is now bundled with the OS X Code42 server installer.

  • Enabling archive key password security is no longer allowed from the administration console for users in organizations that use SSO. Instead, users are instructed to enable archive key password from the CrashPlan app. This prevents a known issue that could lead to the archive becoming inaccessible.
  • Corrects an issue introduced in version 5.0 which could allow users to make changes to locked backup sets.
  • Corrects an issue in which the the web-enabled licensing store could switch to the local licensing screen.

Maintenance Update

Recommended Upgrade
We recommend all Code42 environments running version 5.1.2 or earlier upgrade to version for critical security updates.

Version contains the following fix for customers upgrading from version 5.1.2. If you are upgrading from an earlier version, see the complete list of features, fixes, and enhancements introduced in version 5.1.

  • Corrects a security vulnerability that could allow unauthorized remote code execution.

Known Issues

  • When the CrashPlan app is installed per user on a Windows device, executing the shutdown command from the CrashPlan CLI requires the user to sign out of Windows and sign in again in order to restart CrashPlan.
  • Moving a child organization to a different parent organization causes the child organization to inherit scheduled bandwidth settings from the parent organization, but not inherit any other Device Backup Default settings.
  • On Linux devices with Java 1.6, attempting to upgrade CrashPlan app version 4.3 to version 4.4 or 4.5 fails in some circumstances, and may download multiple copies of the upgrade file. To correct this issue, install Java 1.7, then uninstall and reinstall the CrashPlan app.
  • On slower network connections, administrators attempting to upload the Code42 server upgrade file to the master server may see the administration console session time out before the upgrade completes. To correct this issue, open the administration console CLI and enter prop.set c42.auth.token.timeout 5400000. This temporarily increases the authorization token limit to 90 minutes.
  • In the File Search web app, searching between two dates does not include results that match the end date. For example, to search for files modified between 6/10 and 6/16, enter an end date of 6/17.
  • When the CrashPlan app is installed with user privileges on a Linux device, users may be required to manually start the CrashPlan service after restarting the device.
  • On Windows devices, the CrashPlan service does not start if the user selects the default installation method (for everyone) but then navigates back in the installation wizard and changes to a per user installation. To correct this issue, uninstall the CrashPlan app and reinstall per user. 
  • Devices running Windows Server 2012 R2 do not upgrade to the CrashPlan app version 4.5.2 when installed per user. To use the CrashPlan app on Windows Server 2012 R2, use the default (for everyone) installation method.
  • In some cases, the administration console can incorrectly display a sending limit of 0.00 Mbps for device backups. This does not reflect the actual state of device backups; devices still back up at the defined rate, but the Devices > Network summary may display the rate as 0.00 Mbps.
  • While upgrading the Code42 app from the Code42 console, a message says the Code42 app will be upgraded to an earlier version. This is only a UI issue. Devices upgrade to the correct version of the Code42 app (4.x or 5.x) in use by each organization.
