Get started with Code42

The Code 42 backup application is now available to the majority of CALS-OIT managed computers, both PC and Mac. We are prompting CALS faculty and staff, on computers that do not yet have Code 42, to do that now. These prompts will continue weekly until you install the program and begin to backup your computer. There are benefits and considerations to be aware of before backing up, especially from off-campus, so we have the below information and our team is available to help you decide how or when to complete your first backup.

Why to install Code 42:

  1. EZ-Backup costs you, your lab or your department money based on usage. Code 42 is centrally funded so you won't see additional bills for using it.
  2. Once Code 42 is installed and completes a backup, we will work with your department to turn off EZ-Backup accounts, if you have one.
  3. We have had over 1,000 computers install Code 42 as of June, 2020 and have not seen any failures.
  4. Once your first full backup is complete, subsequent backups usually only take a few minutes as they only transfer new and changed files.
  5. Backups go directly from your computer to Code 42's Cornell contracted space in the cloud, so you do not need to use the VPN to backup.
  6. Backups to Code 42 are encrypted before leaving your computer and on Code 42's servers.

Possible concerns:

  1. If you have limited or very slow internet at home your first backup might take a very long time.
    1. You could start the backup in the evening or over a weekend.
    2. You can also take your computer to a location with a faster internet connection.
  2. If you have limited or very slow internet at home, scheduled backups could interfere with other uses of bandwidth; including Zoom sessions.
    1. You can pause Code 42 for 1 hour, 4 hours or 1 day right from the application icon.

      Backups will begin automatically once the pause period is over.
  3. If you have a limited amount of bandwidth, you might exceed your data cap, especially during your first backup.
    1. Suggestions for this will depend on the size of your data cap, your average use and the data on your computer. Please contact CALS-OIT to discuss.

If you have any concerns about installing Code 42 or backing while off-campus, feel free to let us know what your concerns are at help.cals.cornell.edu One of our technicians can help you determine the what options you have and recommend a course of action.
