n8n Workflow: Backup & Restore n8n Workflows with Telegram, Google Drive, and Form Upload

This n8n workflow provides a comprehensive solution for managing backups and restorations of your n8n workflows. It integrates with Telegram for notifications, Google Drive for storage, and offers a flexible trigger mechanism including manual execution, scheduled backups, and even a form submission for initiating actions.

What it does

This workflow automates the following key processes:

1. Triggering Options:
   • Manual Trigger: Allows for on-demand execution of the workflow.
   • Schedule Trigger: Configures automated backups at specified intervals (e.g., daily, weekly).
   • Form Submission Trigger: Enables external systems or users to initiate backup/restore actions by submitting a form with specific parameters.
2. Conditional Logic: Evaluates the incoming data (e.g., from the form) to determine whether the action is a "backup" or a "restore."
3. Backup Process (Conditional TRUE branch):
   • Lists n8n Workflows: Retrieves a list of all active workflows from your n8n instance.
   • Loops Over Workflows: Processes each workflow individually.
   • Converts to File: Transforms each workflow's JSON data into a file format suitable for storage.
   • Uploads to Google Drive: Stores the workflow backup files in a designated Google Drive folder.
   • Sends Telegram Notification: Notifies a specified Telegram chat about the successful backup, including details like the number of workflows backed up.
4. Restore Process (Conditional FALSE branch):
   • Retrieves from Google Drive: Fetches workflow backup files from Google Drive.
   • Loops Over Files: Processes each backup file individually.
   • Extracts from File: Converts the backup file back into n8n workflow JSON data.
   • Creates/Updates n8n Workflows: Imports or updates the workflows in your n8n instance using the extracted data.
   • Sends Telegram Notification: Notifies a specified Telegram chat about the successful restoration, including details like the number of workflows restored.
5. Error Handling & Aggregation:
   • Uses an Aggregate node to combine results from looped operations before sending final notifications.
   • Includes a Wait node, potentially for rate limiting or to allow time for external services to process requests.
   • Utilizes Code nodes for custom logic or data manipulation if needed (though the provided JSON doesn't show specific code, their presence indicates flexibility).

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance where this workflow will be imported and executed.
• Telegram Account & Bot: A Telegram bot token and chat ID for sending notifications.
• Google Drive Account: A Google Drive account with appropriate permissions for file storage. You'll need to set up Google Drive credentials in n8n.
• n8n API Key (for n8n node): An n8n API key to allow the workflow to interact with your n8n instance (e.g., list, create, or update workflows).
• n8n Form Trigger (Optional): If you plan to use the form submission trigger, ensure your n8n instance is publicly accessible or configured to receive webhooks.

Setup/Usage

1. Import the Workflow:
   • Copy the provided JSON content.
   • In your n8n instance, go to "Workflows" and click "New".
   • Click the three dots menu (...) and select "Import from JSON".
   • Paste the JSON content and click "Import".
2. Configure Credentials:
   • Locate the Telegram node and configure your Telegram Bot API credentials (Bot Token).
   • Locate the Google Drive node and configure your Google Drive (OAuth2) credentials.
   • Locate the n8n node and configure your n8n API credentials.
3. Configure Nodes:
   • Telegram Node: Update the Chat ID in the Telegram nodes to your desired recipient.
   • Google Drive Node: Specify the target folder ID for backups and the source folder ID for restores.
   • If Node: Review and adjust the conditions in the If node if your logic for distinguishing between backup and restore differs.
   • Schedule Trigger (Optional): If you want automated backups, activate and configure the Schedule Trigger node with your desired interval.
   • n8n Form Trigger (Optional): If you want to use the form trigger, activate it. You can then access the form URL from the node settings to integrate with other systems or share it.
4. Activate the Workflow: Once configured, activate the workflow to enable it to run.
5. Execute:
   • Manually trigger the workflow using the Manual Trigger node.
   • Wait for the Schedule Trigger to execute (if enabled).
   • Submit data to the n8n Form Trigger endpoint (if enabled) with a payload that matches the If node's conditions for backup or restore.
