No write key while trying to restore Windows 10

default 11:09:53.864494 -0500 Winclone 6 No write key
Should I be worried about this error? It was extracting data with a progress bar when I went to bed. When I later checked on the status, the progress bar was gone and the log stated the message ‘No write key’.

If it was a critical error, you would see an error dialog box. You can ignore it.
