Hi, it's Shii-chan!

AWS What's New aws.amazon.com

AWS DataSync, the data transfer service, got a nice update!

What was announced?

According to AWS What's New, DataSync Enhanced mode gained three things:

  • Amazon FSx for OpenZFS as a source or destination location
  • NFS version 4.2 for on-premises NFS servers and FSx for OpenZFS file systems
  • A new ObjectMetadata option for object storage transfers

The story so far

Transfers to or from FSx for OpenZFS were limited to Basic mode. And to transfer from NFS servers on the latest version, you had to reconfigure them to an older protocol version.

What changes

  • You can use Enhanced mode for FSx for OpenZFS transfers
  • You can transfer from NFS 4.2 servers without downgrading them
  • You can choose whether an object's user metadata is copied

Dive Deep

The ObjectMetadata option controls whether an object's user metadata is copied to the destination. Two use cases are mentioned:

  • When destination metadata must stay intact, such as buckets served by AWS Storage Gateway
  • When source metadata keys are not compatible with the destination, such as Azure Blob Storage

Existing tasks are unaffected and keep running as scheduled. These capabilities are available for Enhanced mode tasks in all AWS Regions where DataSync Enhanced mode is supported.

Wrap-up

  • FSx for OpenZFS works with Enhanced mode
  • NFS 4.2 is supported
  • ObjectMetadata controls metadata copying
  • Existing tasks are not affected

This one is for anyone planning migrations from OpenZFS or newer NFS servers!
