Bandwidth of s3 batch replication

Question

Hello,

I am migrating n amount of data between 2 buckets in the Tokyo region using s3 batch replication.
I can only do it through AWS console to meet some requirements.

My questions are:-

1. What is the default bandwidth at which the data transfer will be for s3 in Tokyo region?
2. How to increase the bandwidth?
3. Does the bandwidth increase if I increase the 'replication transfer rate' service quota for s3?

Accepted Answer

Hi,

I have not found exact data related to the default bandwitch on Amazon S3 batch replication, but the following [AWS blog entry](https://aws.amazon.com/blogs/storage/how-kurtosys-quickly-completed-a-massive-cross-region-data-migration-using-amazon-s3-batch-replication/) mention that over 100 TB of data and 600 million objects across multiple S3 buckets are replicated on 87 hours. It may serve as a high level reference, but as they point out, duration would vary based on several factors, such as network connectivity, individual object size, any rules.

Also in the following [Reddit post](https://www.reddit.com/r/aws/comments/ci4pr9/cross_region_s3_transfer_speed_50gbs/), a user mentions that he has replicated 122 TB of data and 3.7 mil objects from North Virginia to Ohio in less than 6 hours (47.58 Gb/s approximately).
