Compress and archive old Google Drive PDFs to AWS S3 cold storage with Slack reports

Consolidate and compress project archives for cost-optimized cloud storage

🎯 Description

Optimize your cloud storage costs by using this automation to intelligently compress and migrate aging project documentation. This workflow allows you to achieve a professional data lifecycle policy by identifying "stale" files in active storage, applying high-ratio PDF compression, and migrating them to cold storage while maintaining a searchable audit trail.

A critical technical feature of this template is the Luxon-based lifecycle logic. By utilizing {{ $now.minus({ months: 6 }).toISODate() }}, the workflow dynamically filters for files that haven't been modified in over half a year. It then generates a unique archive path using {{ $now.toFormat('yyyy/MM_MMM') }}, ensuring your cold storage bucket remains perfectly indexed by year and month without any manual folder creation or renaming.

✨ How to achieve automated storage optimization

You can achieve an enterprise-grade archiving system by using the available tools to:

1. Monitor and age-gate — Use the Google Drive node to list project files and a Code node to compare file metadata against a 6-month "hot storage" threshold.
2. Compress and verify — Pass identified files through the HTML to PDF compression engine to reduce file size by up to 80% while maintaining document readability.
3. Migrate to cold storage — Stream the compressed binary directly to AWS S3 (or a dedicated archive folder), using dynamic naming conventions for organized retrieval.
4. Log and notify — Automatically alert the IT team via Slack upon batch completion, providing a report on the specific files migrated and the storage path used.

💡 Key features

• Intelligent cost reduction — Automatically targets large, old files for compression, significantly reducing long-term "Cold Storage" billing.
• Dynamic indexing — Uses Luxon to build a chronological folder structure in the cloud, making multi-year archives easy to navigate.
• Integrity assurance — The workflow ensures files meet specific age and type criteria before moving them, preventing accidental archival of active documents.

📦 What you will need

1. Google Drive — Your "Hot" storage where active project files are kept.
2. HTML to PDF Node — Used here for the PDF compression and optimization engine.
3. AWS S3 — Your destination "Cold" storage for long-term archiving.
4. Slack — For automated reporting on storage optimization status.
