Automated workflow backup with intelligent change detection using GitHub

Advanced n8n Workflow Sync with GitHub

A robust workflow to back up and synchronize your n8n workflows to a GitHub repository, with intelligent change detection and support for file renames.

🎯 Who's it for?

This workflow is for n8n administrators, developers, and power users who want a reliable, automated way to:

• Keep a version-controlled history of their workflows.
• Collaborate on workflows using GitHub's infrastructure.
• Prevent data loss and have a disaster recovery plan for their n8n instance.

✨ Key Features (What it does)

• Intelligent Sync: Backs up all your n8n workflows to a designated GitHub repository.
• Human-Readable Filenames: Saves workflows with filenames based on their actual names in n8n (e.g., My Awesome Workflow.json).
• Reliable Matching: Uses the unique n8n workflow ID to reliably track files, even if their names change.
• Rename Detection: If you rename a workflow in n8n, it intelligently deletes the old file and creates a new one in a single logical operation.
• Efficient Commits: Commits changes to GitHub only when there are actual modifications to a workflow's logic or structure. It performs a deep comparison, ignoring metadata changes.
• Clear Commit History: Generates clean, informative commit messages:
  • create: workflowName
  • update: workflowName
  • rename: oldName - newName

⚙️ How It Works (Simple Steps)

1. Get n8n Workflows: The workflow starts by fetching all your current workflows from n8n.
2. Get GitHub Files: At the same time, it lists all existing workflow files from your GitHub repository.
3. Compare & Decide: It then compares each n8n workflow with its GitHub counterpart. It checks if anything changed, if it was renamed, or if it's new.
4. Take Action:
   • If a workflow is new, it's created on GitHub.
   • If a workflow is updated, the file content is changed on GitHub.
   • If a workflow was renamed, the old file is deleted, and a new one is created.
   • If nothing changed, the workflow is skipped.
5. Send Report: Finally, it can send a summary report to Telegram about what happened.

🚀 How to Set Up

1. Credentials:

   • GitHub: Go to Credentials > New and add your GitHub credentials. You'll need a token with repo permissions.
   • n8n API: In the same Credentials section, create n8n API credentials. You'll need your n8n instance's Base URL and an API key (you can create one in your n8n user settings).
   • Telegram (Optional): If you want notifications, add your Telegram Bot credentials.

2. Configure the Workflow:

   • Open the Configuration node (the green one at the start).
   • Fill in the following values:
     • repo.owner: Your GitHub username or organization name.
     • repo.name: The name of the repository for backups.
     • repo.path: The folder inside the repository to store workflows (e.g., workflows/).
     • report.tg.chatID (Optional): Your Telegram chat ID for notifications. Set to 0 to disable.
     • report.verbose: Set to true to receive a report even if there were no changes.

3. Connect Credentials:

   • Select your newly created credentials in the following nodes:
     • Get all workflows: Select your n8n API credentials.
     • All GitHub nodes (e.g., List files, Create new file): Select your GitHub credentials.
     • Send a message (Telegram): Select your Telegram credentials.

4. Set the Schedule:

   • In the Schedule Trigger node, configure how often you want the backup to run (e.g., every hour, once a day).

5. Activate the Workflow:

   • Save the workflow and toggle it to "Active".

🔧 How to Customize

• Change Report Destination: The final part of the workflow sends a report to Telegram. You can easily replace the Send a message node with a node for Slack, Discord, or email to change where notifications go. The message is pre-formatted in the Render summary node.

💡 What's Next? (Future Updates)

This workflow is actively maintained! Here's a sneak peek at what's planned for future versions:

• Automatic Archive Handling: The next major update will introduce logic to automatically detect when a workflow is archived in n8n and move it to a dedicated archived/ folder in your GitHub repository, keeping your main backup directory clean.
• Performance Optimizations: I'm exploring ways to reduce API traffic by intelligently checking for changes before fetching full workflow data.
