Ever enabled S3 versioning but noticed it’s not working as expected? I’ve been there. Here how I would troubleshoot it:
1️⃣ Ensure Versioning is Enabled
– Go to S3 → Select your bucket → Properties → Check if versioning is enabled.
– If it’s disabled, turn it on and test again.
2️⃣ Check Permissions
– Go to IAM → Policies → Ensure your role has “s3:PutObjectVersion” permissions.
– Without this, versioning won’t work properly.
3️⃣ Verify Lifecycle Policies
– Go to S3 → Select your bucket → Management → Lifecycle rules.
– Ensure no policies are deleting older versions automatically.
4️⃣ Use AWS CLI to Confirm Versions Exist
– Run “aws s3api list-object-versions –bucket your-bucket-name”
– If no versions appear, something is preventing versioning from working.
5️⃣ Check CloudTrail Logs for Changes
– Go to CloudTrail → Event History → Search for “PutBucketVersioning”.
– This will show any changes made to versioning settings.
