Automated workflow backups from self-hosted n8n to Google Drive with version history

✅ What problem does this workflow solve?

If you're using a self-hosted n8n instance, there's no built-in version history or undo for your workflows. If a workflow is accidentally modified or deleted, there's no way to roll back. This backup workflow solves that problem by automatically syncing your workflows to Google Drive, giving you version control and peace of mind.

⚙️ What does this workflow do?

• ⏱ Runs on a set schedule (e.g., daily or every 12 hours).
• 🔍 Fetches all workflows from your self-hosted n8n instance.
• 🧠 Detects changes to avoid duplicate backups.
• 📁 Creates a dedicated folder for each workflow in Google Drive.
• 💾 Uploads new or updated workflow files in JSON format.
• 🗃️ Keeps backup history organized by date.
• 🔄 Allows for easy restore by importing backed-up JSON into n8n.

🔧 Setup Instructions

1. Google Drive Setup

• Connect your Google Drive account using the Google Drive node in n8n.
• Choose or create a root folder (e.g., n8n-workflow-backups) where backups will be stored.

2. n8n API Credentials

• Generate a Personal Access Token from your self-hosted n8n instance:
  • Go to Settings → API in your n8n dashboard.
  • Copy the token and use it in the HTTP Request node headers as:

    Authorization: Bearer <your_token>
    

3. Schedule the Workflow

• Use the Cron node to schedule this workflow to run at your desired frequency (e.g., once a day or every 12 hours).

🧠 How it Works

Step-by-Step Flow:

1. Scheduled Trigger

   • The workflow begins on a timed schedule using the Cron node.

2. Fetch All Workflows

   • Uses the n8n API (/workflows) to retrieve a list of all existing workflows.

3. Loop Through Workflows

   • For each workflow:
     • A folder is created in Google Drive using the workflow name.
     • The workflow’s last updated timestamp is checked against Google Drive backups.

4. Smart Change Detection

   • If the workflow has changed since the last backup:
     • A new .json file is uploaded to the corresponding folder.
     • The file is named with the last updated date of the workflow (YYYY-MM-DD-HH-mm-ss.json) to maintain a versioned history.
   • If no change is detected, the workflow is skipped.

🗂 Google Drive Folder Organization

Backups are neatly organized by workflow and version:

/n8n-workflow-backups/
├── google-drive-backup-KqhdMBHIyAaE7p7v/
│ ├── 2025-07-15-13-03-32.json
│ ├── 2025-07-14-03-08-12.json
├── resume-video-avatar-KqhdMBHIyAaE8p8vr/
│ ├── 2025-07-15-23-05-52.json

Each folder is named after the workflow's name+id and contains timestamped versions.

🔧 Customization Options

• 📅 Change Backup Frequency
  Adjust the Cron node to run backups daily, weekly, or even hourly based on your needs.

• 📤 Use a Different Storage Provider
  You can swap out Google Drive for Dropbox, S3, or another cloud provider with minimal changes.

• 🧪 Add Workflow Filtering
  Only back up workflows that are active or match specific tags by filtering results from the n8n API.

2. Download the desired .json file (based on the date).
3. Open your self-hosted n8n instance.
4. Click Import Workflow from the sidebar menu.
5. Upload the JSON file to restore the workflow.
