In this practical session, we walked through setting up S3 Replication using a source and a target bucket. We tested Cross-Region Replication (CRR), uploaded files, and observed how versioning and delete markers work in replication.

1. Creating Source and Destination Buckets

To start, we created two S3 buckets:

✅ Source bucket: s3-stephane-bucket-origin-v2 (Region: eu-west-1).

✅ Target bucket: s3-stephane-bucket-replica-v2 (Region: us-east-1).

🔹 Note: If both buckets were in the same region, this would be Same-Region Replication (SRR).

2. Enabling Versioning

Before enabling replication, we enabled versioning on both the source and target buckets. This is a mandatory step since replication only works with versioned buckets.

3. Uploading a File to the Source Bucket

• We uploaded beach.jpg to the origin bucket.
• Since replication was not set up yet, this file did not replicate to the target bucket.

4. Configuring Replication Rules

Steps to Enable Replication:

1. Go to the source bucket (s3-stephane-bucket-origin-v2).
2. Navigate to Management → Replication Rules.
3. Click Create Replication Rule and name it "DemoReplicationRule".
