 - Azure File Sync does not support storage account failover. Storage accounts containing Azure file shares being used as cloud endpoints in Azure File Sync should not be failed over. Doing so will cause sync to stop working and may also cause unexpected data loss in the case of newly tiered files.
 - Storage accounts that have hierarchical namespace enabled (such as for Data Lake Storage Gen2) are not supported at this time.
 - A storage account containing premium block blobs cannot be failed over. Storage accounts that support premium block blobs do not currently support geo-redundancy.
