AWS Datasync helped me move a large amount of data from my old self-managed fileshare to AWS Managed FSX for windows file server around a couple of GB in a few minutes. It is easy to use and the service uses an agent or VM that makes reads and writes. Review collected by and hosted on G2.com.

when it comes to very large amounts of data AWS Datasync can't help you because it takes a lot of time, resources and an amount instead of AWS Datasync you can choose AWS Snowball or Snowball Edge for Data migrations. Review collected by and hosted on G2.com.
