The HFS Code42 Cloud Backup Service

Introduction to Code42.

Code42 has been selected by the University as the recommended tool for securing backups of university data on personal, single-user computers like your desktop and laptop at work and at home. It is a cloud based backup product that replaces the existing Spectrum Protect backup solution with key features including: near-continuous automatic backup in the background, unlimited storage, multiple file versions allowing point-in-time restore and many more benefits.

Key points in the migration to Code42 are:

  1. Initially, the Code42 backup service is open to existing HFS desktop/laptop backup service users only. Clients will then be contacted by email and asked to register for the Code42 service.
  2. Existing backup data will not be migrated. Client users will back up their data afresh to the Code42 cloud. Once these are running reliably and after 90 days from registration to the Code42 service, the client’s old backups held by the current HFS desktop/laptop service will be removed.
  3. You will need to be running a modern, supported operating system to run Code42. Currently this includes Windows 10 and 8.1, macOS Mojave 10.14, Catalina 10.15 and Big Sur 11. Linux is supported for recent 64-bit distributions using rpm or Debian packaging. This includes, but is not limited to Ubuntu 16.04 and later, Debian 9 and later, Centos 7 and later, Fedora 32 and later and distributions based on these. Full details of end user environment requirements can be found on these Code42 pages and the links from them. Linux users please note that the library dependencies listed will be installed by the HFS Hub app and do not therefore need installing prior to Code42 installation.

The migration process to the HFS Code42 Cloud Backup Service

When you are contacted by email to ask you to register for the Code42 service, please first check the simple decision chart to determine whether it is a suitable backup solution for all or some of your machines. The HFS Spectrum Protect Backup Service may offer an alternative solution, subject to its own qualifying criteria.

The HFS Hub app manages the three processes of registration, software download and installation and is available from the relevant link below:

HFS Hub for Windows

HFS Hub for Mac (Intel)

HFS Hub for Mac (Apple Silicon)

HFS Hub for Linux (Ubuntu, Debian etc.)

HFS Hub for Linux (Fedora, OpenSUSE, Centos 8 etc.)

HFS Hub for Linux (Centos 7)

Download and run the HFS Hub app; the first screen will report any account name your machine has with the legacy HFS Desktop Backup Service. It will also display an option to install Code42, if it detects that no Code42 software is currently installed.

The next screen will ask you to register for the Code42 service. If you select register and you are already registered it will allow you to update your registration details. Note that the contact email address asked for, is only stored within the HFS Portal and not stored with Code42.

The next screen prompts the user to start the code42 software installation. This may take a few minutes, please be patient.

On completion of the installation, the final screen will appear. Note that it may be obscured by the initial screen of the Code42 application starting, in which case, minimize or otherwise move the Code42 screen to follow the final instructions:

As per the text on screen, but for added clarity, when you return focus to the Code42 screen, it will prompt you for your username: this is your Oxford SSO login name (e.g. and the server name to connect to: enter in this field (you can copy and paste this from the final HFS Hub window) and click Continue. You will then be taken to the familiar Oxford SSO screen to re-enter your SSO username and password.

Once authenticated, the Code42 app will set itself up, and you may see the message ‘Signing in …’ displayed for some time. Please be patient and allow this to complete. Thereafter on a newly installed machine, the first dialogue screen will now offer you the choice of registering this machine as a new device to back up to the Code42 cloud, or as a replacement device. In most cases you will choose the 'New Device' option. If your current machine is indeed a new replacement for an old machine that has failed and for which Code42 backups exist, choose the 'Replacement' option and follow the prompts.

The Code42 app is now set up and ready to use. Extensive online support on using the Code42 app is available from the Code42 support pages (choose the Backup and Restore tab) and select the 'Code42 for Enterprise' option where a choice is available. A brief introduction to the Code42 interface is also included on our Getting Started with Code42 page while other questions may be answered on our HFS Code42 FAQ page.
