# View and modify file level retention properties

Network-attached storage is a file-level storage architecture that makes stored data more accessible to networked devices.

## About this task

When a snapshot is created, it can be configured to have no automatic deletion or retention until a specific date and time. If retention is set, the snapshot is automatically deleted upon reaching the retention date. This does not prevent the snapshot from being deleted before the retention date.

See Understanding PowerMax File for storage systems for an overview of PowerMax File.
