I want to take backup of my newly refreshed sandbox org. While doing so via MavensMate, it is showing oAuth error like below. 
Is this the issue for all newly created/refreshed orgs ??. 
If yes, I want to know how to take backup of org via vs code directly without mavens.
Thanks in advance.

It's a basic question. How to rename Lightning component once created?  I couldn't find any menu on Devloper console and any buttons on Setup|Develop|Lightning Components. Is it necessary to delete and create new one with new name?
