Amazon FSx for NetApp ONTAP

There is no Block level replication available, you can use AWS DataSync, since you are asking for copy from Fsx Windows to FSx Netapp i assume it is CIFS/SMB filesystem you can use robocopy also. Any file based copy tool will work. Thanks

As Arun already pointed out, AWS DataSync would be my recommendation and favorite for this use case. It’s a managed service that simplifies the process while ensuring high scalability and reliability. However, for smaller data volumes or one-time migrations where you’d rather avoid configuring an additional service, you can definitely go 'old school' with Robocopy. This native Windows utility is a great way to maintain NTFS permissions (ACLs) without the need for extra infrastructure. If you are already within the NetApp ecosystem or need to continuously synchronize data across diverse sources - such as S3 to ONTAP or Windows to ONTAP - NetApp BlueXP (formerly Cloud Manager) offers a specialized service that integrates seamlessly with ONTAP management.

Hi There

We recommend using AWS DataSync to transfer data between FSx for ONTAP file systems and non-ONTAP file systems, including FSx for Lustre, FSx for OpenZFS, FSx for Windows File Server, Amazon EFS, Amazon S3, and on-premises filers.
