During a paused restore, you have an opportunity to temporarily modify or clean up problematic data such as uploads or posts in the database before Discourse proceeds with completing the restoration process. Here’s how you can handle or modify the problematic data during a paused restore step-by-step.

Steps to Manually Handle Problematic Data in a Paused Restore

1. Initiate the Restore with Pausing:
   Run the restore with the --pause flag to allow the restoration process to pause before uploads or remappings are applied:

   cd /var/discourse
   ./launcher enter app
   discourse restore --pause <backup_filename>
   

2. Point of Pausing:

   • The restore will pause during specific points:
     1. Before database migrations: Press a key to proceed during this point, as it doesn’t concern problematic uploads or posts.
     2. Before uploads are restored: Stop here to modify any uploads or post content-related issues. This is the critical point where you need to act.

3. Open a New SSH Session:
   While the restoration is paused, open a new SSH session to interact with the paused instance without interrupting the restore process:

   cd /var/discourse
   ./launcher enter app
   

4. Access the Rails Console:
   Enter the Rails console to interact with the database:

   rails c
   

5. Identify Problematic Posts:

   • Use SQL-like queries in Rails to identify posts that include problematic content causing issues during backup restoration. For example:

     current_db = RailsMultisite::ConnectionManagement.current_db
     cdn_path = SiteSetting.cdn_path("/uploads/#{current_db}/original").sub(/https?:/, "")
     Post.where("cooked LIKE '%#{cdn_path}%'")
     

   This will return posts where the cooked content includes problematic upload paths or onebox links.

6. Modify or Delete Problematic Posts:

   • If you locate the problematic post(s), you have two primary options:
     • Edit the Post:

       post = Post.find(ID) # Replace ID with the post's ID
       post.update(cooked: "Fixed content or placeholder text")
       

     • Delete the Post:

       post = Post.find(ID)
       post.destroy
       

7. Modify Uploads if Necessary:
   If the issue stems from specific problematic uploads:

   • Locate them using similar queries in the uploads table (accessible via Rails console).
   • Remove or correct the problematic entries:

     upload = Upload.find(ID) # Replace ID with the problematic upload's ID
     upload.destroy
     

8. Resume the Restore Process:
   After making necessary modifications, return to the paused shell session and press any key to resume the restore process.

Important Considerations:

• Always create a backup of the original database file before modifying any content.
• Focus on correcting minimal data—that is, only address problematic content without making unnecessary changes.
• If the upload is external (a URL or CDN-related issue), you can remove the external reference manually during restoration.
