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 GUI-based backup product to the Cloud that replaces the existing Spectrum Protect backup solution with many benefits including frequent automated backups in the background, unlimited storage and multiple file versioning allowing point-in-time restores.
Key points in the migration to Code42 are:
- existing data held with the HFS will not be migrated: clients will back up their data afresh to the Code42 cloud.
- Code42 is supported on the following modern operating systems:
- Windows 10 and 11.
- macOS High Sierra 10.13, Mojave 10.14, Catalina 10.15, Big Sur 11 and Monterey 12.
- most recent 64-bit Linux distributions using rpm or Debian packaging (further details of supported operating systems can be found on these Code42 pages .)
The Code42 Cloud backup service is best suited to backing up single-user machines, or machines where a single user can take ownership of the backups (the HFS Spectrum Protect Backup Service may offer an alternative solution, subject to its own qualifying criteria ).
Installing the HFS Code42 Cloud Backup App
Installation of the Code42 app is a simple two-stage process: First you download the HFS Hub and install that. This then manages the installation and configuration of the Code42 backup app. So, first step is to download the HFS Hub via the appropriate link below (Apple users click the Apple logo in the top left of your screen and choose 'About this Mac' to find out if your Mac has an Intel or Apple chip):
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)
Now run or open the downloaded file.
Note If you are a Windows Edge browser and see a 'blocked' message after downloading the Hub for Windows file, see Item 1.11 on the FAQ page (under eligibility and access).
Windows and Mac users will see a setup screen. Choose the button to cause the HFS Hub to be installed. Once done, the HFS Hub will run and display the following screen, reporting any account name your machine has with the legacy HFS Desktop Backup Service and an option to install Code42, if it detects that no Code42 software is currently installed.
Choose the 'Install Code42' button in the centre of the window. The next two screens will prompt you to download Code42 and then confirm the download as complete, as below.
Choose the 'Next' button to display the next screen that explains the need to register for the Code42 backup service - or confirm your registration, if already registered.
Choosing the 'Register' button will take you the Oxford single sign on prompt. Once authenticated here the following screen will display, asking you to enter an email contact address, so that the service can contact you about this account. Note: this information is held only by the HFS service and not shared with any other external service provider.
Note: your contact email address will default to your primary email address, but the field does allow the choice of an alternative address or the entry of a new address.
Choosing the 'Update' button registers your contact email address and proceeds to the following screen.
Click the 'Start Installation' button. Once the Code42 installation is complete, the following confirmatory screen displays:
This screen may be obscured by the Code42 Sign In screen. If so, move the Code42 screen temporarily to one side in order to follow the final instructions. Note the server address highlighted in the centre and then click the 'All Done' button to close this screen. Now return focus on the Code42 Sign On screen as below:
Enter the following information: in the Username field enter your SSO login that you have registered with Code42 previously. This should be in the form firstname.lastname@example.org i.e. don't forget the @ox.ac.uk bit.
In the Server Address enter clients.eu5.cpg.crashplan.com.
Now click 'Continue' to 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 …’ or a screen similar to below displayed for some time.
Please be patient and allow this to complete. Thereafter, if you have already installed Code42 on another separate machine already, 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 for one of your other machines. You will normally choose the 'New Device' option. (If your current machine is indeed a new replacement for another machine that has failed and for which Code42 backups exist, choose the 'Replacement' option and follow the prompts.) If you are installing Code42 for the first time on your one and only device, you should not be prompted as above.
The Code42 front screen will now display and is ready for you to make a selection for backup (note: by default nothing is included). A further note: If you have a large amount of data to backup initially, at least 1TB or more, then please see sections 2.13 and 2.16 on the 'HFS Code42 Cloud Backup: FAQ' site.
A brief introduction to the Code42 interface is available on our Getting Started with Code42 page. 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. Common questions around the Oxford implementation of Code42 backup may be answered on our HFS Code42 FAQ page.
