How much can I save using this migration skill?

By moving large datasets from Cloudflare R2 to AWS Glacier Deep Archive, you can achieve over 90% cost savings, reducing storage costs from ~$15/TB to ~$1/TB.

Can the migration resume if the process crashes?

Yes, the skill utilizes a JSON-based checkpoint system to track progress, allowing you to resume transfers exactly where they left off using the --resume flag.

Is there a way to test the migration before committing?

Yes, the skill supports a dry-run mode to count objects and a small batch testing mode to verify credentials and connectivity before starting a full transfer.

How do I monitor the progress of a transfer?

You can use provided commands to check active screen sessions, tail remote log files via SSH, or inspect the current checkpoint JSON file.

What storage class does this skill target in AWS?

It is specifically configured for the DEEP_ARCHIVE storage class in AWS S3, which offers the lowest storage price point for long-term data retention.
