Overview

Every backup archive created with the CrashPlan app is tied to a specific computer through a unique computer ID. This way, CrashPlan can keep a thorough and unique record of each computer's backup history (previous file versions, moved and deleted files, etc.). In certain situations, you may need to assign your computer a new ID. This article describes the process of assigning your computer a new ID.

Considerations

  • You might need to assign your computer a new ID if:
    • You have cloned a Virtual Machine
    • You recently changed computers with the help of a utility like Migration Assistant or Time Machine
    • Our Customer Champions ask you to do this when troubleshooting an issue
  • CrashPlan's uninstaller does not reset your computer identity. If you want to completely remove traces of your previous installation, you must reset the identity using the instructions below.

Steps

  1. Open the CrashPlan app
  2. Double-click on the logo in the upper right
    CrashPlan Logo
    A command window opens
  3. In the input area, type: guid new
    You are signed out of the
    CrashPlan app

That's it! Now it is as if you installed the CrashPlan app for the first time on that computer.
