### Idempotent versions on delete markers

Duplicate delete markers are not created on MinIO buckets with versioning, if an application performs a soft delete on an object repeatedly - that object will only ever have a single DELETE marker for all such successive attempts. This is done to ensure that repeated soft deletes do not ever need multiple versions in the first place.

It must be noted that if active-active replication is set up with delete marker replication, there is potential for duplicate delete markers to be created if both source and target concurrently set a Delete Marker or if one/both of the clusters went down at tandem before the replication event was synced.This is an unavoidable side-effect in active-active replication caused by allowing delete markers set on a object version with `REPLICA` status back to source.

    ]
}
```

### 3.3 Automatic removal of delete markers with no other versions

When an object has only one version as a delete marker, the latter can be automatically removed after a certain number of days using the following configuration:

```

    "Rules": [
        {
            "ID": "Removing all delete markers",
            "Expiration": {
                "ExpiredObjectDeleteMarker": true
