How to Setup Amazon S3 Replicate All Objects Across Buckets

What Is Amazon S3 Replication

Amazon S3 replication can automatically replicate an object from one bucket to another, a process that can help enterprises with disaster recovery and mass data migration. Also, the process of replication is done asynchronously, which means that any updates made in the source bucket will happen in the target bucket in a short period.

Two Types of Amazon S3 Replication

1. Cross-Region Replication (CRR)

CRR allows replication across different AWS regions, which happens to be very useful for disaster recovery for data maintenance in remote locations.

2. Same-Region Replication (SRR)

SRR only allows replication within the same AWS, and this replication process is typically used in data-heavy buckets and is performed on the assumption that multiple copies of the data are stored in the same location.

How to Replicate Data in AWS

Setting up Amazon S3 replication allows you to automatically replicate objects from one S3 bucket to another within the same AWS region (Same Region Replication, SRR) or across different regions (Cross Region Replication, CRR). This is useful for data backup, disaster recovery, compliance, or reducing data access lags. Here is a step-by-step guide on how to set up S3 replication.

Step 1. Enable Versioning on Both Bucket

1. Go to the AWS Management Console and navigate to S3.

2. Navigate to Buckets and click Create bucket.

3. Choose the bucket you want to replicate objects from

4. Go to the Properties tab > Bucket Versioning > Edit, click Enable and then Save.

Step 2. Configure Replication Rules

1. Go to the source bucket where replication will be configured. Then navigate to Management tab, under Replicate Rules, click Create Replication Rule.

2. Give the rule a name that helps identify its purpose, and under the Status click Enabled to enable the replication rule.

📌Note: If the replication rule is disabled, the replication process will not run.

3. You can select Apply to all objects in the bucket to replicate all objects. Alternatively, you can configure the rule by selecting Limit the scope of this rule using one or more filters to apply only to objects with a certain prefix or a tag.

4. Select the destination bucket where you want to copy the objects. The buckets can be in the same region (for SRR) or different regions (for CRR).

5. S3 replication requires permission to perform replication operations. You can create a new IAM role or select an existing role.

Step 3. Review and Save Replication Configuration

Review the replication rules to ensure that everything is set up correctly, including the source bucket, target bucket, and IAM role permissions. After ensuring that the configuration is done, click Save to activate the replication rule.

Question: Amazon S3 won’t Replicate Old Objects

Amazon S3 replicates all objects expect old objects, which means Amazon S3 replication does not automatically replicate old objects, any object that was in a data bucket before the replication rule was configured. Replication in S3 only applies to objects created or updated after replication rules are enabled.

When a replication rule is created, it takes effect from the time it is set, but only for newly created or modified objects. This underlying mechanism was designed to ensure efficient use of resources and to avoid triggering mass replication of potentially large data sets without user control.

Simple Steps to Backup via AOMEI Cyber Backup

Step 1. To Add Target, you need to go to Target Storage and select Amazon S3. After opening the add target page, enter Username, Password, and Bucket, then click Confirm.

Step 2. Go to Backup Task to Create New Task and start archiving your data to Amazon S3. For example, you can select File Backup and choose files or folders for backup.

Step 3. Select Archiving backup versions to Amazon S3 and click Select to choose the added Amazon S3.

Step 4. Schedule backup tasks to run daily, weekly, or monthly, and choose backup retention policies to automatically delete old backups.

Step 5. Select Start Backup to begin the backup process. It will first create a local or NAS backup and then upload it to Amazon S3.

Conclusion

Amazon S3 replication is a powerful tool for organizations to ensure data durability and compliance across AWS regions. The process of automated replication provides seamless disaster recovery and data access performance. With the addition of AOMEI Cyber Backup, data is better utilized and protected.
