Restoring Data from a Snapshot
You can restore data in two ways:
● Restore individual files: After a snapshot is created, the FluidFS cluster creates a client-accessible snapshots directory
containing a copy of the files included in the snapshot. Clients can easily restore individual files from a snapshot using copy
and paste, without storage administrator intervention. This method is useful for the day-to-day restore activities of individual
files.
● Restore a NAS volume from a snapshot: The storage administrator can restore an entire NAS volume by rolling the state
back to the time of an existing snapshot. This method is useful in the case of an application error or virus attacks.
Snapshots retain the same security style as the active file system. Therefore, even when using snapshots, clients can access
only their own files based on existing permissions. The data available when accessing a specific snapshot is at the level of the
specific share and its subdirectories, ensuring that users cannot access other parts of the file system.

Restore a NAS Volume From a Snapshot
The storage administrator can restore an entire NAS volume from a snapshot. The restored NAS volume will contain all the NAS
volume data that existed at the time the snapshot was created. Each file in the restored NAS volume will have the properties,
such as permission and time, that existed when you (or a schedule) created the snapshot.
