FAQPage Schema
How do I migrate data from Cloudflare R2 to AWS Glacier Deep Archive?▼

Migrate Cloudflare R2 objects to AWS Glacier Deep Archive using streaming transfer with batched archiving. The Skill handles large-scale migrations with checkpoint-based resume, concurrency-controlled downloads, and credential-based access to archive billions of objects cost-effectively for long-term storage.

Can I resume an R2 to Glacier migration if it gets interrupted?▼

Yes, the Skill supports checkpoint-based resume. Progress is saved automatically, allowing interrupted transfers to restart without reprocessing completed objects, essential for large-scale migrations across R2 buckets.

What's the best way to handle large-scale archiving without loading everything into memory?▼

Streaming transfer with batching is the optimal approach for large-scale archiving. The Skill streams objects from R2 directly into Glacier Deep Archive in batches (e.g., 50,000 objects per archive), eliminating memory overhead.

Does this Skill support dry-run before running a full migration?▼

Yes, dry-run mode is supported. Test your migration parameters and estimate costs without transferring actual data, then run the production migration when ready using CLI-driven workflows.

What credentials and setup do I need before migrating to Glacier?▼

You need Cloudflare R2 credentials and AWS S3 credentials with Glacier Deep Archive access. The Skill uses credential-based authentication for both platforms to enable secure streaming transfers.
