Learn how to back up or replicate your Cloudflare R2 data to AWS S3 in a user-friendly way—without touching the command line.

The Why Behind Syncing R2 and S3

While Cloudflare R2 stands out with its zero egress fees, making it a cost-effective storage choice, AWS S3 still dominates with a mature ecosystem—including lifecycle rules, encryption, and regional availability. Syncing data from R2 to S3 offers the best of both worlds—cost savings with strategic resiliency.
