Description

Automatically BackUp Your n8n Workflows to OneDrive

This workflow automates the backup of your self-hosted n8n instance by exporting all workflows and saving them as individual .json files to a designated OneDrive folder. Each file is timestamped for easy versioning and audit tracking.

After a successful backup, the workflow optionally cleans up old backup files and sends a confirmation email to notify you that the process completed.

How it works

1. Uses the HTTP Request node to fetch all workflows via the /rest/workflows API.
2. Iterates through each workflow using SplitInBatches.
3. Converts each workflow to a .json file using Set and Function nodes.
4. Uploads each file to a target Microsoft OneDrive folder using OAuth2.
5. Deletes old backup files from OneDrive after upload, with the option to keep backups for a configurable number of time.
6. Sends an email notification once all backups have completed successfully.

Setup instructions

• Enter your n8n Base URL and authentication details in the HTTP Request node.
• Set up Microsoft OneDrive OAuth2 credentials for cloud upload.
• Configure the Email node with SMTP credentials to receive backup confirmation.
• (Optional) Adjust the file retention logic to keep backups for a set duration.
• A Cron trigger to schedule the workflow automatically (e.g., daily or weekly).

👉 Sticky notes inside the workflow explain each step for easy setup.
