Amazon FSx, a fully managed file system service, added support for copying file system backups across AWS opt-in Regions, which are regions disabled by default. This update applies across FSx for Windows File Server, Lustre, and OpenZFS, facilitating cross-region and cross-account backup and recovery beyond default-enabled regions.

Previously limited to enabled regions, customers can now use the AWS console, API, or CLI to copy backups into and out of opt-in Regions within the same account, or across accounts in an AWS Organization via AWS Backup. This broadens resiliency and compliance architectures for disaster recovery scenarios.
