Amazon Simple Storage Service S3 Replication provides you the control to meet the data sovereignty and other business needs. It is a fully-managed, cost-effective, flexible feature that duplicates recently uploaded objects to two or more Amazon S3 buckets, keeping them in sync. Syncing existing objects between Amazon buckets is now possible with S3 batch replication.
But how to use Amazon S3 batch replication? Here’s our answer!

Amazon S3 Batch Replication
Developments in technology have allowed the creation of more and more products, some of which are intangible and are in the cloud. An example of this is the Cloud services of Amazon Web Services (AWS). It is a cloud service provider that enables you to meet your data and computing needs in cloud computing mode.
Amazon S3 is the primary storage service of AWS that can store a “virtually” unlimited amount of data with very high availability. It is an object storage service with various features for the organization and management of data cost-effectively, increasing security and meeting compliance needs. It is a viable solution for scalability and data availability with optimal safety and performance.
The great particularity of Amazon S3 lies in object mode storage. Unlike block mode storage or file storage, an object in Amazon S3 is composed of data and metadata and responds to API.
Whether it’s about replicating a new bucket with the existing objects, retrying to replicate previously failed objects, relocating data between different accounts, or making additions to your data lake with new buckets, you can use S3 batch replication. In addition, it works with any data volume and enables you to control it in a fully managed way to meet your needs concerning:
- data security
- compliance
- disaster recovery
- performance optimization

Amazon S3 Features
The various features of Amazon S3 allow managing data of any volume, structured or unstructured, for the use cases discussed above. All the data is stored in buckets as objects, where the size of each object can be up to 5 terabytes.
Amazon S3 features enable:
- adding metadata tags to those stored objects,
- relocating and storing the data between S3 storage classes,
- configuring and enforcing data access controls
- protecting unauthorized access to data
- performing Big Data analytics
- monitoring object and bucket level data
- viewing the usage of storage and other activity trends in the organization
You can access the objects directly from the hostname assigned to the bucket or S3 Access Points.
When to Use Amazon S3 Batch Replication?
Amazon S3 batch replication can be used by entities belonging to any sector in any of the following cases:
- for building and scaling data lake of any volume of structured or unstructured data in optimal protection and in a cost-efficient way
- for backing up and restoring critical data in a flexible, durable, scalable, and cost-efficient way
- for storing data at low cost in the cloud with Amazon S3 Glacier storage classes for data archival in the most flexible way
- for running cloud-native applications (collections of microservices using Application Programming Interfaces (API) to access cloud storage) in a secure and scalable environment\
With a few clicks, you can get started with this feature. Let’s discuss how to use it!
How to Use Amazon S3 Batch Replication
Amazon S3 data resides in buckets with multiple directories and subfolders. While creating the back, you need to choose a region to optimize latency and reduce data access costs. Following are the steps to configure Amazon S3:
- Create an S3 Bucket
Create an S3 bucket by:- Opening an account for the AWS Management Console and logging in
- Once you log in, search for S3
- Then click ‘Create Bucket,’ which takes you to the page where you have to enter the Name of Your Bucket
You can configure permissions for the S3 bucket in several ways. You can change the default permission, which is ‘Private,’ through the AWS Management Console. It is always best to be selective by adding only necessary permissions for optimal security while granting access to your newly created S3 buckets. - You can choose tags, versioning, Object-Level Logging, and default encryption among the different configure options. All these options are optional.
- Finally, create the bucket by clicking on ‘Create Bucket’
- Upload Files to the Created S3 Bucket
You can upload files to your created S3 bucket by:- Clicking on the bucket name
- Then, click on ‘Upload,’ followed by clicking ‘Add Files’ and adding the desired file
- Finally, click ‘Upload’
You can see on the screen the respective document you selected uploading into your created bucket.
- Access Bucket Data
You can access an AWS S3 bucket data by clicking on the file you want to access by accessing the URL, which takes you to a screen that tells you that you don’t have access to the objects in the bucket. Fix this issue by:- Navigating ‘Bucket Permission’
- Clicking ‘Edit’ and unchecking ‘Block All Public Access’
- Then, click ‘Save,’ making the uploaded file public.
Now you can reach the object URL.
Remember that bucket names must be unique since they are universal namespaces. The screen displays an HTTP code 200 after successfully uploading an object to an S3 bucket.
Security and Encryption on Amazon S3
By default, S3 buckets are private. The different Amazon S3 data access control mechanisms include:
- AWS IAM (Identity and Access Management) policies for authorizing IAM users to have viscous control over their Amazon S3 bucket
- Bucket policies for adding or denying permissions on objects in a bucket
- Access Control Lists (ACLs) to grant certain permissions to particular objects
- Query String Authentication to share Amazon S3 objects
AWS can automatically encrypt data at rest with several key management solutions for encryption. Therefore, it is possible to configure S3 buckets to encrypt objects automatically. Alternatively, using client-side data encryption before uploading to S3 is still possible.

Small Disadvantaged Business (SDB) provides access to specialized skills and capabilities contributing to improved competitiveness and efficiency.
Client-side encryption
The client-side encryption method manages your own keys, knowing that the data remains encrypted in the S3 buckets. The loss of the latter means the impossibility of using this data again.
In transit
Data transfers from or to Amazon S3 can be encrypted with an SSL/TLS certificate.
At rest
Server-side encryption on Amazon S3 uses 256-bit AES symmetric keys. There are three ways to manage keys. Amazon S3 Server Side Encryption (SSE-S3) natively encrypts data by managing encryption keys.
For more functionalities, it is possible to use AWS Key Management Service (SSE-KMS), which manages authorizations for the use of keys and an access statement, thus allowing to benefit from an additional level of control and consult data access attempts. With SSE-KMS, the keys are managed in AWS KMS. With SSE-C (Customer Provided Keys), Amazon S3 can also encrypt data at rest using customer-provided encryption keys.
