MinIO does not assume or require that the client-provided key is unique. It may be used for multiple objects or buckets. Especially a single client-provided key may be used for all objects - even though all objects must be treated as compromised if that key is ever compromised.

#### Key rotation

`PENDING` state.

This is a slower operation that does not use replication queues and is designed to walk the namespace and replicate objects one at a time so as not to impede server load. Ideally, resync should not be initiated for multiple buckets simultaneously - progress of the syncing can be monitored by looking at `mc replicate resync status alias/bucket --remote-bucket <arn>`. In the event that resync operation failed to replicate some versions, they would be picked up by the healing mechanism...
