Enabling Windows EFS Support


When you want to back up and restore EFS files, you need to run CrashPlan “as user” and set the proper permissions. This article describes how to tell CrashPlan to run “as user.”

Before You Begin

  • Install CrashPlan as you normally do.
  • Test to see if CrashPlan is already running as user.

How It Works

  1. From the Windows desktop, click Start > My Computer > Manage.
    The Computer Management windows opens.
    From the Start menu, you can also choose Run and type Services.MSC
  2. In the Services window, double-click CrashPlan Backup Service.
  3. Click the Log On tab.
  4. Under This Account:
    • In the Username field enter the user name.
      For example, .\username
    • In the Password field enter the password.
  5. Click OK.
  6. In the Permissions message box, click OK.
  7. In the next message, click OK.
  8. Click the Stop button on the toolbar.
  9. Click the Start button on the toolbar.
  10. Restart the system tray.


Following the above steps stops the system tray. Be sure to turn it back on and verify that the system tray is running.

In Windows 7 and Windows Vista, CrashPlan uses the system tray to detect whether or not the user is present or away from the computer. Because CrashPlan works harder when you are away than when you are at your computer, it important that the system tray is running so that CrashPlan knows when it can worker harder and when it can throttle back.

Run as User Test

  1. Open the Task Manager.
  2. Sort the processes and look for CrashPlan Server.
  3. In the Name column should display User.
    If it displays SYSTEM Windows EFS support will not be enabled.
