AWS DataSync is a data transfer service that simplifies, automates, and accelerates moving and replicating data between on-premises storage systems and AWS storage services over the internet or AWS Direct Connect. DataSync can transfer your file data, and also file system metadata such as ownership, time stamps, and access permissions. In DataSync, a location for Amazon FSx for Windows is an endpoint for an FSx for Windows File Server. You can transfer files between a location for Amazon FSx for Windows and a location for other file systems. For information, see Working with Locations in the AWS DataSync User Guide.
