Restoring File Versions in Google Drive
From USD437
Restoring an old version of a file
1. Find the appropriate file in Google Drive as you normally would. Right-click the file name so you get the dropdown menu. Select "Manage Versions."
2. Then, you can select how you want to handle the file. Deleting the top-most file makes the second oldest the "newest" version and is the one saved. You can also download another copy--which I did--to keep locally.
