### 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": {
                "DeleteMarker": true

	// 3. If bucket versioning is enabled and
	//    a. version id is specified, remove its remote object.
	//    b. version id is not specified, nothing to be done (a delete marker is added).
	delTier := false
	switch {
	case !os.Versioned, os.Suspended: // 1, 2.a, 2.b
		delTier = true
	case os.Versioned && os.VersionID != "": // 3.a
		delTier = true
	}
	if delTier {

		return ObjectNameInvalid{Bucket: bucket, Object: object}
	}
	return nil
}

// Checks for all ListObjects arguments validity.
func checkListObjsArgs(ctx context.Context, bucket, prefix, marker string) error {
	// Verify if bucket is valid.
	if !isMinioMetaBucketName(bucket) && s3utils.CheckValidBucketNameStrict(bucket) != nil {
		return BucketNameInvalid{Bucket: bucket}
	}

	[]madmin.ConfigHistoryEntry, error,
) {
	var configHistory []madmin.ConfigHistoryEntry

	// List all kvs
	marker := ""
	for {
		res, err := objAPI.ListObjects(ctx, minioMetaBucket, minioConfigHistoryPrefix, marker, "", maxObjectList)
		if err != nil {
			return nil, err
		}
		for _, obj := range res.Objects {
			cfgEntry := madmin.ConfigHistoryEntry{

}

func (az *warmBackendAzure) InUse(ctx context.Context) (bool, error) {
	containerURL := az.serviceURL.NewContainerURL(az.Bucket)
	resp, err := containerURL.ListBlobsHierarchySegment(ctx, azblob.Marker{}, "/", azblob.ListBlobsSegmentOptions{
		Prefix:     az.Prefix,
		MaxResults: int32(1),
	})
	if err != nil {
		return false, azureToObjectError(err, az.Bucket, az.Prefix)
	}
