Amazon FSx for OpenZFS

Amazon FSx for OpenZFS now supports on-demand data replication across AWS opt-in Regions, enabling you to easily and efficiently transfer incremental point-in-time snapshots of your volumes beyond AWS Regions that are enabled by default. This feature provides a simple and resilient way to implement disaster recovery, replicate production data to a different Region or account, and enable lower latency data access for your global customer base or workforce.

Amazon FSx for OpenZFS provides fully managed, cost-effective, shared file storage powered by the popular OpenZFS file system, with rich data management capabilities like snapshots, data cloning, and compression, along with sub-millisecond latencies and up to 10 GB/s of throughput. Opt-in Regions are AWS Regions that are disabled by default, in contrast to regions that are enabled by default. Previously, on-demand data replication was supported only between accounts in AWS Regions that are enabled by default. Starting today, you can replicate snapshots to and from opt-in Regions, expanding the AWS Regions where you can build cross-Region disaster recovery and data distribution architectures.
