Rewind can only retrieve and restore saved data/previous versions of the store that have already been backed up within the Rewind app itself.
For example, if Rewind was installed and had its first automatic backup run on October 4th, 2017, at 12:00pm, this would be the earliest date and time Rewind would be able to go back to restore backups of that site. Anything prior to this would not exist in Rewind's database.
However, there may still be a way to manually retrieve some of your lost information/data from Google's cache.
We highly recommended some of the following links to help better understand how to use Google's cache to retrieve lost data:
- Google Search Help - Cache
- How to Find Old Websites & Search Cached Pages in Google
- Chrome Cache Viewer to View/Recover Chrome Cache Files
- How Do I Use Google's Cache to Restore a Web Page?
