In PowerStoreOS 3.0 and later, users can enable File Level Retention (FLR) on General type file systems. FLR is used to prevent modification or deletion of locked files within the file system until a specified retention date has passed. PowerStore supports both FLR-Enterprise (FLR-E) and FLR-Compliance (FLR-C), which have different functionality and use cases. Both FLR types support snapshot creation, the modification of a limited number of snapshot properties, snapshot refresh, and snapshot deletion. The snapshot Restore operation is only supported on FLR-E file systems and cannot be run on FLR-C file systems.
For more information about file system types and File Level Retention, review the Dell PowerStore: File Capabilities white paper on the PowerStore Info Hub.
