Anything you've archived can be restored. All restored content is brought back in the draft and can be republished.
- In the Toolbox section of the homepage, navigate to the Site Center > Tools tab.
- Click the View List button for undeleting pages and minisites.
- On the next page, check the box next to the item you wish to restore and click Undelete.
You can follow the same instructions from a Minisite Center. In that case, you'll only see the list items archived from that Minisite whereas the Site Center allows you to restore anything archived from anywhere on the site.
