AWS DataSync

AWS DataSync uses a purpose-built network protocol and multi-threading architecture to accelerate the movement of massive datasets between on-premises storage and AWS. It automatically handles the parallelization of data streams, bypassing the bottlenecks of standard TCP transfers to fully saturate high-bandwidth network connections. This allows enterprises to migrate petabytes of data significantly faster than traditional rsync or scp commands.

Yes, AWS DataSync encrypts data both in transit and at rest to ensure strict compliance with enterprise security standards. All data transferred over the internet or through AWS Direct Connect is secured using TLS encryption. Once the data arrives at its destination—such as Amazon S3 or Amazon EFS—it is automatically encrypted at rest using AWS Key Management Service (KMS).

AWS DataSync is compatible with a wide variety of storage systems, including Network File System (NFS), Server Message Block (SMB) shares, and self-managed object storage. On the AWS side, it integrates natively with Amazon S3, Amazon EFS, and Amazon FSx for Windows File Server. This extensive compatibility makes it incredibly easy to transfer data from legacy on-premises NAS devices directly into the AWS cloud.

AWS DataSync is priced based on the exact amount of data transferred from your source storage to the destination AWS service. You are billed a flat rate per gigabyte, which covers both the compute resources used to accelerate the transfer and the network costs. There are no minimum fees or setup costs, making it highly cost-effective for one-time data migrations or continuous replication workflows.
