Migrating to the New Code42 CrashPlan Service


In March 2022 Code42 informed the University that, due to internal restructuring, they must change the location of our backups. This required the reconfiguration of the Code42 client on each machine and a fresh backup of the data. The vast majority of users completed this process.

If you were using the old service on your computer and haven't moved to the new service this is what you must do .

Moving to the new service - a step by step guide

Before you start, please minimise all other windows. This will help with window management later in this process where multiple windows can be open, but are hidden underneath other windows.

Start the HFS Hub app. It will very likely prompt you that a newer version of the Hub is available. Please upgrade, if prompted. You should be running version 1.3.0 (select the Help menu -> About option) at the minimum.

From the HFS Hub choose the Code42 menu item and then the 'Change Service' option (MacOS users will find the Code42 menu at the top of the screen)

At the next screen review the processes that are to be completed and click the 'OK' button

At the next screen click the 'Download now' button to download the latest Code42 client software

Once downloaded click the 'Next' option

At the next screen, click the 'Register' button to create an account for you on the new Code42 service. Note: you will be prompted for your SSO login at this point.

Now just confirm the email contact details the HFS has for you by clicking the 'Update' button


c42 new mig 06


At the following screen, click the 'Start reinstallation' button


c42 new mig 07


The next screen will display. Note: that you will be asked to confirm permission for the reinstall process and the window requesting this may be hidden under the existing Hub window (or other windows you may have open). If you cannot immediately see this window, please search for it on your desktop (by minimising or moving other windows, if necessary). If you do not grant permission, the following screen will appear to hang indefinitely.

Once the reinstallation is complete the following screen will appear.


c42 new mig 09

Copying your settings is no longer available as we can no longer obtain that information from the old service so just click Cancel at this point and wait for the Code42 app to start and prompt you for your Username and Server Address as below:


c42 new mig 10


Please ensure you enter your full SSO login name with ox.ac.uk appended in the Username field, and clients.eu5.cpg.crashplan.com in the Server Address field and then click the 'Continue' button. 

You will now be taken to a browser window to enter your SSO login again. Once done, please follow the browser window instructions and close the browser window to return to the Code42 window. 

The Code42 window may display a 'Signing in ...' message for a time, while it sets itself up.

You may then see the following screen, if you have already moved one device over to the new service.


c42 new mig 11


If so, click the 'Add New Device' button.

You will now see the following familiar Code42 screen as below ...


c42 new mig 12


... however, you will note the message in that screen 'No files selected for backup.'

Click on Add files to set up files for backup. You will also have to change any other settings that you want changed.

Note: Code42 will now immediately start to backup your files afresh. This may not be convenient at this time, as it may take considerable time, depending on the amount of data you have to backup. You can defer this process for 60 minutes each time you choose either the 'Pause Backups' option on the front screen or by choosing the Tools menu and 'Pause Code42' option. If you need to pause Code42 for longer please see the CrashPlan support page Stop and start the CrashPlan app service

Please note that if you have more than one computer, then you will need to do the entire step by step guide as above on all of your machines.
