Amazon FSx for Lustre, a fully managed service that makes it easy and cost effective to launch, run, and scale the world’s popular high-performance file system, now supports the ability to free up storage capacity on an FSx file system that has data synchronized with Amazon S3.

FSx for Lustre integrates natively with Amazon S3, synchronizing changes in both directions with automatic import and export, so that you can access your S3 data lakes through a high-performance POSIX-compliant file system on demand. Starting today, you can use the FSx API to release inactive data that is on the file system and has already been exported to S3. You can choose to only release data from files that have not been accessed for a minimum amount of time and to only release data within a specified directory path. When a file is released, the file data is removed from your file system (and retained on S3) and the metadata remains on your file system. If a user or application accesses a released file, the data is automatically and transparently loaded back onto your file system from your S3 bucket. To release data on a regular interval, you can schedule the FSx API using Amazon EventBridge.

The ability to release file system data is available on all new and existing FSx for Lustre file systems running Lustre version 2.12 in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD. For more information about releasing file system data, visit the Amazon Web Services storage blog or see the Amazon FSx for Lustre documentation.
