operations. The version being deleted on the source cluster needs to maintain state and ensure that the operation is mirrored to the target cluster prior to completing on the source object version. Since this needs to account for the target cluster availability and the need to serialize concurrent DELETE operations on different versions of the same object during multi DELETE operations, the current implementation queues the `DELETE` operations in both sync and async modes.

The MinIO TLS STS API can be configured via MinIO's standard configuration API (i.e. using `mc admin config set/get`). Further, it can be configured via the following environment variables:

```

If one or more drives are offline at the start of a PutObject or NewMultipartUpload operation the object will have additional data protection bits added automatically to provide additional safety for these objects.
