How to restore Supabase backup?

 

Step 1: Access Your Supabase Project

 

To start the process of restoring from a backup, you need to log in to your Supabase account and navigate to your specific project. Here’s how to access it:

• Open your web browser and go to the Supabase website.
• Click on Login and enter your credentials.
• Once logged in, you will be directed to your Supabase dashboard.
• Select the project where you want to restore the backup.

 

Step 2: Download Supabase CLI

 

To restore a backup, you need to use the Supabase Command Line Interface (CLI). Here’s how to download and install it:

• Visit the Supabase CLI GitHub releases page.
• Download the appropriate version of the CLI for your operating system (macOS, Windows, or Linux).
• Follow the installation instructions specific to your operating system.

 

Step 3: Authenticate the CLI

 

Once you have installed the CLI, you need to authenticate it with your Supabase account:

supabase login

• Open a terminal or command prompt.
• Execute the command above. This will open a browser window asking you to authenticate.
• After authentication, return to the terminal to continue.

 

Step 4: Retrieve Your Backup File

 

Before restoring, you need the actual backup file that you will utilize. This could be a SQL dump file that was exported previously.

• Ensure that you have the backup file stored on your local machine.
• If it is stored remotely (e.g., cloud storage), download it to your local system.

 

Step 5: Connect to Your Supabase Database

 

Before you restore, connect to your Supabase database locally:

supabase db reset

• This command resets your local development database.
• Ensure your local environment is configured correctly with PostgreSQL if needed.

 

Step 6: Restore the Backup

 

Now, apply the backup file to restore your database:

PGPASSWORD= pg_restore --username= --host= --dbname= --clean --if-exists 

• Replace <YOUR_SUPABASE_PASSWORD>, <YOUR_SUPABASE_USERNAME>, <YOUR_SUPABASE_HOST>, and <YOUR_SUPABASE_DBNAME> with your respective database details.
• <path-to-backup-file> should be replaced with the path to your downloaded backup file.
• The option --clean removes any existing data before restoring.

 

Step 7: Verify the Restore Process

 

After restoration, ensure that your data has been restored properly:

• Go back to the Supabase dashboard.
• Navigate to your project's Database section.
• Check if all the tables, procedures, and data have been restored correctly.

 

Step 8: Address Any Errors

 

In case of any errors during the restore process, investigate the following:

• Review the error messages displayed in the terminal for clues.
• Ensure the backup file is not corrupted or incomplete.
• Consult the Supabase documentation for troubleshooting advice.

 

By following these steps, you should be able to successfully restore a backup onto your Supabase project. Remember to keep your backup files secure and regularly updated.
