Auto-Backup n8n Workflows to OneDrive with Cleanup & Email Notifications

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

Uses the HTTP Request node to fetch all workflows via the /rest/workflows API.
Iterates through each workflow using SplitInBatches.
Converts each workflow to a .json file using Set and Function nodes.
Uploads each file to a target Microsoft OneDrive folder using OAuth2.
Deletes old backup files from OneDrive after upload, with the option to keep backups for a configurable number of time.
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.
