Windows user permissions requirements for CrashPlan for Small Business


In the default Windows installation (installing the Code42 app for everyone on the device), Code42 relies on the read/write permissions of the Windows system account to access your files. However, there are some files or folders the system user may not have permission to access. Alternatively, your organization's systems administrator may have removed the system account from the permissions list.

If you need to back up these files or directories, follow this tutorial to re-add the system account to their permissions lists.


The Code42 app on Windows computers


  • The Windows system account is used by services and processes within Windows to log on internally. This account has administrator-level access to most files. This means that Code42 can use the Windows system account to access and back up system files that are typically inaccessible to a logged-in user.
  • The system account is on most Windows computers by default.

Recommended solution

Add system permissions

  1. From Windows Explorer, right-click the file or directory that needs the SYSTEM account added and select Properties.



  1. Select the Security tab and click Edit.

Security Properties

  1. Click Add.

Add Permissions

  1. Type SYSTEM into the box and click OK.

Enter SYSTEM User

  1. Click Apply and OK.

After you update your permissions, you can tell the Code42 app to scan your backup set for file changes to start back up the files.
