Automated AWS S3, Azure, Google Cloud to MinIO Backup Scheduler

This workflow enables automated, periodic backups from major cloud storage providers—AWS S3, Azure Blob Storage, and Google Cloud Storage—to a MinIO bucket, which can run locally, in a container like Proxmox LXC, or on remote infrastructure. It leverages official APIs: listing and downloading objects from the source, then uploading them via MinIO's S3-compatible interface. Scheduling ensures regular execution without manual intervention, supporting compliance, disaster recovery, and data migration needs.

Key benefits include cost-effective local storage to reduce cloud egress fees, scalability for large object sets, and flexibility to swap MinIO for other S3 providers like Backblaze or Wasabi. Ideal for storage admins, cloud architects, and DevOps teams managing multi-cloud environments, it minimizes downtime risks and simplifies hybrid storage strategies.

Use cases span backup for development environments, archiving critical data, or syncing across providers. No special requirements beyond source/destination credentials and MinIO setup; easily integrates into larger workflows for custom needs like FTP/SFTP sources.
