DataSync for Amazon FSx

Question

Hello
I would like to ask what is the difference between these two configuration methods:

Way 1: https://aws.amazon.com/blogs/storage/how-to-replicate-amazon-fsx-file-server-data-across-aws-regions/

Way 2: https://www.youtube.com/watch?v=c4XQMDUVHU8

The case is as follows. I have 2 Amazon FSx, in two different regions, and I would like to implement synchronization between Amazon FSx in region X, and Amazon FSx in region Y using DataSync.

Which method should I choose? I think method number 2 is better because of the lack of additional VM, I think it will be more cost effective. But I am not sure if there is not some hidden issue here that I should pay attention to?

I would appreciate any help on this topic. Best regards.

Accepted Answer

You would use a Datasync Agent when [you're using self-managed storage](https://docs.aws.amazon.com/datasync/latest/userguide/working-with-agents.html) (including an NFS share in an AWS VPC, other cloud providers, or on-prem storage).

Directly answering the question, I think the difference between them is that the blog posting is over 2 years old, as[ the current documentation](https://docs.aws.amazon.com/datasync/latest/userguide/how-datasync-works.html#in-cloud-transfer) doesn't show an agent in the reference architecture for transfers between AWS storage services.
