## 3. Activate ILM versioning features

This will only work with a versioned bucket, take a look at [Bucket Versioning Guide](https://docs.min.io/community/minio-object-store/administration/object-management/object-versioning.html) for more understanding.

### 3.1 Automatic removal of non current objects versions
