Customers typically have business requirements or policies for their enterprise that require creating more copies of their existing Amazon S3 objects. Although S3 Replication on Amazon S3 Replication is extensively used to copy newly added things across S3 buckets, the easiest method to replicate large numbers of things already in S3 buckets needs to be clarified to a lot of users. In this blog, we’ll explain how to activate Cross-Region Replication (CRR) for existing objects using Amazon S3 Replication.
Amazon S3 Replication is a controlled, low-cost, elastic solution to copy items from an Amazon S3 bucket to another. Through Amazon S3 Replication, it is possible to create rules that instantly replicate S3 objects across multiple AWS Regions with the help of Amazon S3 Cross-Region Replication (CRR). Alternatively, you can make rules for the replication of objects between buckets in the exact AWS Region through the Amazon S3 Same-Region replication (SRR). To learn more about what’s replicated and not replicated using S3 Replication, look at our guidelines.
Customers can transfer existing objects to another bucket within the same or another AWS region by contactingcontacting the AWS support team to enable this function to the bucket currently being used as a source. Once the ability to replicate existing objects has been activated in a source bucket, customers can utilize S3 Replication on all of their existing things and recently uploaded items. When the replication process is completed, the customer will have two buckets with all objects. Newly uploaded objects will be replicated into the bucket they are to go to.
The current object replication is a feature that extends the already existing S3 Replication feature and includes all of the same features. It allows you to replicate objects while keeping metadata (such as the date of creation and time), replicate things across distinct storage categories, and keep replicas of objects under different ownership. Amazon S3 Replication Time Control (S3 RTC) can also be enabled when configuring existing object replication. But be aware that S3 RTC only affects newly uploaded objects, not existing ones.
We will show you how to enable and configure S3 Replication on existing objects.
Setup replication for objects that already exist
Update: Amazon S3 Batch Replication was launched on the 8th of February 2022, permitting you to duplicate the existing S3 objects and sync with your S3 buckets. Check out the S3 User Guide for more information. AWS Support no longer manages the current object replication service.
To enable the existing replication of objects to your AWS account, contact Support at AWS. This is necessary to ensure that the image is properly configured. To avoid your request being delayed, send your AWS Support request the topic “Replication for Existing Objects” and make sure you include the following details:
Note: When the support ticket is submitted, AWS Support will work with the S3 team and allow you to list your bucket to allow object replication.
When AWS Support has enabled support to replicate existing objects in your bucket, it’s an ideal practice to check the configuration of your replication. Before you apply to a more extensive set of data, it is possible to test the validity of the design, as well as the permissions and permissions, by setting up the test bucket/prefix in a small size. This is a crucial step since there isn’t a simple method to restart replication on unsuccessful objects.
Remember to check the conditions before enabling replication. This includes ensuring that the buckets used for source and destination are allowed for versioning.
Starting to replicate existing objects using S3 Replication
In this example, we are replicating the entire source bucket (s3-replication-source1) in the us-east-1 Region to the destination bucket (s3-replication-destination1) in the us-west-1 Region. Additionally, we have set the destination’s storage class to S3 Standard-Infrequent Access.
Once your source bucket is allowed to be listed, and you have been granted permission to record it, you can create your replication rules as follows:
Part I. Set up a replication rule within the Amazon S3 console. Amazon S3 console
This is where we create an underlying replication rule for the bucket used as the source. This includes deciding on the objects we want to replicate and making it possible to replicate existing objects.
1. Log into your Amazon S3 Management Console and open your Amazon S3 console.
2. In the list of buckets, select the bucket from which you are sourcing that is allowed-listed (by AWS Support) for the existing replication of objects.
3. Click on the Management tab of the bucket. In the section titled Replication Rules, select the Create Replication Rules. The rule’s creation also allows the standard CRR or SRR to be placed in the bucket.
4. Give the replication rule a name and choose whether you wish your rule activated or disabled upon its creation. The name of the law is mandatory to be distinct within your bucket.
Note that if the bucket runs already established replication rules, you’ll be requested to determine the rule’s priority. This will help avoid conflicts caused by objects which are part of the
