Auto-Cleanup Cloudflare R2 Files >2 Weeks + Telegram Alerts

This workflow automates the cleanup of old files in a Cloudflare R2 bucket using S3-compatible API. It triggers daily via a schedule node, lists all files in a specified folder, filters those unmodified for over 2 weeks using custom JavaScript code comparing timestamps, deletes the qualifying files one by one, and immediately notifies via Telegram with details like file name and deletion time.

Benefits include preventing storage bloat, reducing costs on cloud bills, and maintaining organized buckets without manual intervention. It's ideal for teams managing large file uploads, such as logs, backups, or temp media, ensuring compliance with retention policies.

Use cases: Social media analytics pipelines dumping daily reports to R2, e-commerce temp files from processing, or any high-volume file storage needing periodic pruning. Customizable for different age thresholds or multiple buckets.
