+###### Important
+
+DataSync supports transfers to and from certain third-party cloud storage systems, such as Google Cloud Storage and IBM Cloud Object Storage, which handle system metadata in a way that is not fully S3-compatible. For these transfers, DataSync attempts to copy metadata attributes such as `ContentType`, `ContentEncoding`, `ContentLanguage`, and `CacheControl` on a best-effort basis. If the destination storage system does not apply these attributes, they will be ignored during task verification.
