Daily n8n Workflow Backup to Nextcloud (7-Day Retention)

This workflow runs on a daily schedule (or manually) to fetch all workflows from your n8n instance using the n8n API with full details including nodes, connections, settings, pinData, and tags. It converts each workflow into a clean, import-ready JSON file, sanitizes filenames, and uploads them to a specified /N8N-Backup directory in Nextcloud, creating the folder if needed.

Key features include automatic 7-day retention: it lists existing backup files, identifies those older than 7 days based on date prefixes, and deletes them to manage storage efficiently. Recent updates fixed the export format for perfect n8n UI compatibility—no arrays or metadata that could break imports.

Benefits: Provides reliable offsite backups for self-hosted n8n instances, prevents data loss, simplifies recovery, and automates maintenance. Ideal for teams relying on n8n for critical automations, ensuring compliance and quick restores without manual intervention.

Use cases: DevOps teams backing up production workflows, agencies managing client n8n setups, or any n8n user wanting secure, versioned storage in Nextcloud with minimal setup (just add credentials).
