can be monitored by configuring event notifications on the source and target buckets using `mc event add`.On the source side, the `s3:PutObject`, `s3:Replication:OperationCompletedReplication` and `s3:Replication:OperationFailedReplication` events show the status of replication in the `X-Amz-Replication-Status` metadata.

On the target bucket, `s3:PutObject` event shows `X-Amz-Replication-Status` status of `REPLICA` in the metadata. Additional metrics to monitor backlog state for the purpose...

*A noticeable trait of this expansion is that it chooses unique hosts such the setup provides maximum protection and availability.*

- Choosing an erasure set for the object is decided during `PutObject()`, object names are used to find the right erasure set using the following pseudo code.
