PowerScale clusters that are using OneFS CloudPools to tier data to a cloud provider have a stub file, known as a SmartLink. The file is retained on the cluster with the relevant metadata to retrieve the file at a later point. Without the SmartLink, a file that is tiered to the cloud cannot be retrieved. If a SmartLink is replicated to a target cluster, the target cluster must have CloudPools active with the same configuration as the source cluster to be able to retrieve files tiered to the cloud.
SmartSync performs a deep copy for dataset creation of data tiered with CloudPools. Deep copy is a process that retrieves all data that is tiered to a cloud provider on the source cluster, allowing all the data to be replicated to the target cluster.
