AWS DataSync Enhancements

AWS DataSync Enhanced mode now supports Amazon FSx for OpenZFS as a source or destination location, NFS version 4.2 for on-premises NFS servers and FSx for OpenZFS file systems, and a new ObjectMetadata option for object storage transfers.

Previously, customers transferring data to or from FSx for OpenZFS were limited to Basic mode.

New Features

  • Amazon FSx for OpenZFS: Enhanced mode now supports Amazon FSx for OpenZFS as a source or destination location.
  • NFS 4.2: Transfer data from NFS servers on the latest version without reconfiguring them to an older protocol version.
  • ObjectMetadata: Control whether an object's user metadata is copied to the destination.
