Version 5.3 of the Code42 platform contains a number of new features, as well as fixes and enhancements. Highlights include:

  • Security updates throughout the Code42 platform
  • A new App Downloads interface to manage the Code42 app versions available in your Code42 environment
  • The ability to enable transport-layer security (TLS) for server-to-server and client-to-server communication
  • New scheduling capabilities for Code42 environments using network-based device backup rates
  • Three new Reporting web app reports

Updated Components

Code42 platform version 5.3 includes updates to the following components:

  • Code42 server for private cloud environments
  • CrashPlan apps for Windows, OS X, and Linux
  • Code42 API
  • Code42 web apps

To upgrade your Code42 environment, see our upgrade instructions.

Security Updates

  • Improves REST API authorization token security.
  • Updates cipher exclusions for compatibility with Java 8 default exclusions.
  • Improves Code42 console security.
  • Improves password reset security.


App Downloads

The Code42 console features a new App Downloads interface to manage the client versions available in your Code42 environment. Administrators can now control and easily update which versions and platforms of the Code42 app are available, and users have a simpler and easier way to access and download the Code42 app.

Transport-Layer Security (TLS) Messaging

Code42 server version 5.3 introduces the ability to enable transport-layer security (TLS) for server-to-server and client-to-server communication. TLS messaging is an industry standard, RFC-compliant method of transport security.

To support TLS connections, Code42 server version 5.3 allows inbound communication (listening) on ports 4287 and 4288, in addition to continuing to listen on ports 4282 and 4283. To prevent incoming communication on the new TLS ports, see our steps for disabling inbound TLS connections.

Network-Based Scheduling

Code42 environments configured to use network-based device backup rates now have the additional option of introducing schedules to define different maximum rates for peak and off-peak times. This enables administrators to limit backup traffic when specific networks and destinations are busy with higher priority network activity.

New Reporting Tools

The Reporting web app includes three new reports:

  • Removes the Deactivate device option from the device menu.
  • Corrects an issue in which customized Code42 app packages configured to lock the server address did not properly prevent users from changing the server address in the Code42 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.

Code42 API

  • Introduces three new resources:
    • OrgBackupReport
    • DestinationBackupReport
    • UserBackupReport
  • Removes the ClientDownloadUrlResource resource. Due to new App Downloads structure, this resource was no longer relevant.
  • The email parameter of the User resource is no longer case sensitive.
  • The API documentation viewer now indicates if a resource requires a feature-specific license.
  • Improves authorization token security.
  • Improves JSON validation of the deviceRateLimitConfiguration resource to reject invalid or misspelled configuration values.
  • Corrects an issue in which some HTTP return status codes were not logged correctly.

Maintenance Update 5.3.2

  • For legal hold preservation policies created with all default settings, corrects an issue in which deleted files were not retained according to the Remove deleted files setting.
  • Corrects an issue in which changing the Remove deleted files setting for an organization from Device Backup Defaults > Backup > Frequency And Versions when it's locked could result in the setting becoming unlocked on user devices. 

Maintenance Update 5.3.1

Recommended Upgrade
We recommend upgrading all Code42 servers running version 5.3.0 and earlier to version 5.3.1 for important client upgrade bug fixes.
  • Corrects an issue which could cause a user's local backups to be removed if that user is moved to an organization that does not accept inbound backups.
  • Changes to the Code42 app Java memory allocation now persist after upgrades.
  • Corrects an issue in which upgrading the Code42 app from version 4.x to 5.x could prompt the user to complete the replace device wizard before resuming backups.
  • Corrects a rare issue which required a small number of users to restart the Code42 app to connect to the Code42 cloud.
  • Upgrading Code42 app devices from one 5.x version to a newer 5.x version no longer requires using the Code42 console command-line interface (CLI) to enable the upgrade in each organization.

Version Compatibility

Code42 server version 5.3.1 is compatible with the following components.

Component Compatible Versions
Code42 app

Windows, Mac, and Linux:

  • 5.3.1
  • 5.3.0
  • 5.2.1
  • 5.2.0
  • 4.7.1
  • 4.7.0
  • 4.6.1
  • 4.6.0

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

Known Issues

  • If the File Selection setting is locked in the Code42 console (Settings > Device Backup > Backup), you must take action to ensure all Code42 app devices are using version 4.5.2 or later before upgrading to Code42 server version 5.3.
  • When the Code42 app language is set to Automatic, the Code42 app always displays in English, even if the system language is different. To switch the Code42 app language, choose another language from Settings > General > Language.
  • In some cases, users may not be able to change their password immediately after registering as a new user in the Code42 app. Signing out of the Code42 app and signing in again corrects this issue.
  • Computer-to-computer backups stop if one computer upgrades to Code42 app version 4.7 and the other computer remains on version 4.6 or earlier. To resume backups, upgrade both devices to Code42 app version 4.7.
  • In very large Code42 environments, navigating to the Devices screen and selecting Show Alerts from the action menu may display devices without alerts in addition to devices with alerts.
  • The Code42 app is now available for download from a new App Downloads screen in the Code42 console. Depending on your browser cache settings, you may need to refresh the Code42 console after the Code42 server upgrade completes to see the new App Downloads screen.
  • To enable Code42 app automatic upgrades from one 5.x version to another 5.x version (for example, upgrading from 5.2 to 5.3), you must follow the steps in Upgrading The Code42 app To Version 5.x.
  • If at any time in the past a user installed Code42 app version 4.x on a second device and was prompted to adopt the old device but never dismissed that prompt, upgrading to Code42 app version 5.x prompts users to complete the Replace Device wizard before resuming backups.
  • 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. 
  • Code42 app version 5.3.1 does not support environments that use both single sign-on (SSO) and Microsoft Active Directory Federation Services (AD FS). To deploy the Code42 app to devices that leverage both SSO and AD FS, use Code42 app version 4.7.1.
  • In very rare cases, using the Code42 console to push version retention setting changes to offline devices can cause corrupt file versions to be backed up once the device comes back online. This issue was introduced in version 5.3.0 and is fixed in version 5.4.0. To avoid potential problems, Code42 recommends either: upgrading to 5.4.0 before making changes to version retention settings using the Code42 console, or making changes to version retention settings from the Code42 app on individual devices.
