The error is pretty clear - do you use CU6 to restore?

Shreedhar EtteCommented:
- Make sure to run the command from elevated command prompt.

- Use this syntax and see:
Setup.exe  /m:RecoverServer /IAcceptExchangeServerLicenseTerms

If it still fails with "copied failed" then download setup once again and extract to another folder and execute above command.
