Mac Migration Assistant, Time Machine, and the Code42 app for CrashPlan for Small Business

Overview

The Code42 app ties every backup archive to its source computer with a unique computer ID. When you migrate the Code42 app using a program like Migration Assistant or Time Machine, the file containing this unique computer ID is transferred from the old computer to the new computer. 

As a result, both computers share the same identity. Changes made in the Code42 app settings on one computer (for example, the computer name) also update on the other computer. Follow this troubleshooting article to assign your new computer a new ID and differentiate the computers for the Code42 app.

Affects

The Code42 app on a Mac using Migration Assistant or Time Machine.

Recommended solution

Perform a complete uninstall and reinstall of the Code42 app on the new device.
