Amazon S3 Replication (CRR, SRR, Batch Replication) vs Dual-region and multi-region buckets (incl. turbo replication) / Storage Transfer Service
S3 Replication maps partly to dual-region and multi-region buckets, which replicate automatically (turbo replication targets a 15-minute RPO for dual-regions), and to cross-bucket replication for independent buckets.
Side-by-side comparison
| Aspect | Amazon Web Services | Google Cloud |
|---|---|---|
| Service | Amazon S3 Replication (CRR, SRR, Batch Replication) | Dual-region and multi-region buckets (incl. turbo replication) Storage Transfer Service |
| Lifecycle | Generally available | Generally available Generally available |
| What it is | Asynchronous replication of new objects to buckets in other Regions (CRR) or the same Region (SRR), Batch Replication for existing objects, and Replication Time Control (RTC) with a 15-minute SLA. Requires versioning on both buckets. | Bucket locations that store data redundantly across regions, with optional turbo replication for dual-region buckets. Managed transfers from Amazon S3, Azure Blob Storage, HDFS, on-premises file systems (through agents), and between Cloud Storage buckets, including event-driven transfers. |
| Pricing model | Destination storage, replication requests, inter-Region data transfer, and a per-GB RTC fee when enabled. | Dual-region and multi-region storage has its own per-GB rates, plus inter-region replication charges for data written. See Cloud Storage pricing. |

Key differences
- Cross-region redundancy is a property of the bucket's location, not a rule you add to an existing regional bucket.
- Cross-bucket replication (built on Storage Transfer Service) covers cases dual-regions don't, such as separate projects.

FAQ
What is the Google Cloud equivalent of Amazon S3 Replication (CRR, SRR, Batch Replication)?
S3 Replication maps partly to dual-region and multi-region buckets, which replicate automatically (turbo replication targets a 15-minute RPO for dual-regions), and to cross-bucket replication for independent buckets.
How does pricing compare between Amazon S3 Replication (CRR, SRR, Batch Replication) and Dual-region and multi-region buckets (incl. turbo replication) and Storage Transfer Service?
AWS: Destination storage, replication requests, inter-Region data transfer, and a per-GB RTC fee when enabled. Google Cloud: Dual-region and multi-region storage has its own per-GB rates, plus inter-region replication charges for data written. See Cloud Storage pricing. Check the official pricing pages for current rates.
What is the Azure equivalent?
Blob Storage object replication and Azure Storage redundancy (LRS, ZRS, GRS, GZRS) (direct match). S3 Cross-Region and Same-Region Replication map to Azure Blob object replication.
