Amazon FSx for NetApp ONTAP

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.

See https://docs.aws.amazon.com/fsx/latest/ONTAPGuide/migrate-files-to-fsx-datasync.html

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
