How to backup profile all data include sign-in-cookie?
For some reason, Chrome seems to have deleted my extensions, settings, and cookies.
Restarting the browser didn't bring them back.
Fortunately, my bookmarks, history, and saved passwords survived.
I looked into it and found that the profile appears to be corrupted, with no apparent way to restore it.
It might have been recoverable right after the corruption occurred, but unfortunately, it seems I launched the browser a few times in this state.
Windows System Restore might work, but unless I'm certain it will restore everything correctly, the risk is high because it would also roll back other applications.
We have to move on,but how to prepare if happen same things?
If I back up the `C:\Users\myaccount\AppData\Local\Google\Chrome\User Data` folder, can I restore everything by copying it back if this happens again?
I do not intend to sync with a Google account.
