S3 replication is beneficial for multiple reasons. Similar to cross-region replication, this solution only replicates new objects added to the source bucket after configuring the function, and does not replicate objects that existed prior to the functions existence. In Serverless Framework, when you have function s3 events, they will automatically create a new AWS S3 bucket, if it doesn't exist . Therefore, we recommend running multiple tests after setting up the different destination functions and, based on the results, rely on this method only for file sizes that consistently manage to replicate. s3_bucket_hosted_zone_id: The Route 53 Hosted Zone ID for this bucket's region. Buckets that are configured for object replication can be owned by the same AWS account or by different accounts.

This tutorial has the following examples on how to setup and manage replication rules on S3 bucket using AWS s3api CLI: View Current Replication Rules on a S3 Bucket Delete All Replication Rules from a S3 Bucket Add New Replication Rule on a S3 Bucket with Default Values Replication Rule with Custom Rule Name At this moment I'm configuring a new CDN for our project. 1. Choose what bucket to replicate To start S3 Replication, go to the Policies section: Here, well create a new policy for this example. For Events , choose ObjectCreated (ALL). I was using Terraform to setup S3 buckets (different region) and set up replication between them. This needs to be created for each instance of the function (for each destination), calling out the respective destination bucket in the policy. The solution leverages S3 event notification, Amazon SNS, and a simple Lambda function to perform continuous replication of objects. code of conduct because it is harassing, offensive or spammy. Replication enables automatic, asynchronous copying of objects across Amazon S3 buckets. 3.

A scenario where you could possibly use this is when you have an application deployed in two regions. Another reason is to copy data to another bucket and have an isolated process running on the data. With SRR, you can set up replication at a bucket level, a shared prefix level, or an object level using S3 object tags. At Cloudway we focus on Cloud Native development. Working with Delete Markers): But this marker will not be copied to the destination bucket, see the What Does Amazon S3 Replicate: If you make a DELETE request without specifying an object version ID, Amazon S3 adds a delete marker. If you already have a predefined schedule for this task, you can specify it here. Verify that the object was copied successfully to the destination buckets.

Check it the "s3:ReplicateDelete" in the Actions must be present: Now remove ReplicationConfiguration, "Filter": {}, "Priority": 1 DeleteMarkerReplication parameters and add "Prefix": "", so this policy will be like Version 1: The problem is that CRR config version 2 still can't do DeleteMarkers replication at this moment, the AWS Support reply was: I did have a look at your blog and the suggestions provided by you seem correct. Now, if we go back to our backup S3 bucket, theres a new file in itone that was just replicated via N2WS Backup and Recovery. An example IAM policy is provided later in this post. Cross-region replication in Amazon S3 lets you copy from one source bucket to one destination bucket, where the destination bucket resides in a separate region from the source bucket. mb stands for Make Bucket. Choose the source encryption key (this should be easy to find since we gave it an alias); Enable "Change object ownership to destination bucket owner" and provide the destination account ID. Amazon S3 must have the permission to copy the objects from one region to another. The user that create the IAM role is passing permissions to Lambda to assume this role. In order for a Lambda function to be able to copy an object, it requires a Lambda function IAM execution role. The buckets can belong to the . For the most part, you will pay $0.09 per gigabyte (up to the first terabyte and slightly less afterwards). Hi, @david 9. To avoid coping data each time to both buckets an AWS S3 Cross-Region Replication can be used, so data from a bucket-1 will be copied to a bucket-2. For example, suppose you configure replication where bucket A is the source and bucket B is the destination. Step 2: Edit parameters of Primary Region and Data Source. Select use case as 'Allow S3 to call AWS Services on your behalf'. It is highly available, durable, and easy to integrate with several other AWS Services. S3 Replication is a fully managed, low-cost feature that replicates newly uploaded objects between buckets. For a successful execution, this should look similar to the following screenshot. Amazon S3 event notifications can notify you in the rare instance when objects do not replicate to their destination Region. Here, we'll use our "n2ws-s3-repo" bucket. Amazon Simple Storage Service (S3) Replication is an elastic, fully managed, low-cost feature that replicates objects between buckets. At first check the IAM role used (see the Setting Up Permissions for Cross-Region Replication). If you have any suggestions or comments, please feel free to comment below.

I created 2 KMS keys one for source and one for destination. Under Sync Destination, choose the target S3 bucket where the replication will occur and a destination prefix, if needed. This solution is presented as a complement to cross region replication for specific use cases that require either multiple destination buckets, or a destination bucket that resides in the same region as the source.
