Delete a Snapshot
Delete a snapshot if you no longer need the point-in-time copy of the data.
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, expand NAS Volumes and select a NAS volume.
4. In the NAS Volume Status panel, click the Snapshots & Clones tab.
5. Select a snapshot and click Delete.
The Delete dialog box opens.
6. Click OK.
Restoring Data from a Snapshot
You can restore data in two ways:
• Restore individual les: After a snapshot is created, the FluidFS cluster creates a client-accessible snapshots directory
containing a copy of the les included in the snapshot. Clients can easily restore individual les from a snapshot using copy and
paste, without storage administrator intervention. This method is useful for the day-to-day restore activities of individual les.
• 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 le system. Therefore, even when using snapshots, clients can access only
their own les based on existing permissions. The data available when accessing a specic snapshot is at the level of the specic
share and its subdirectories, ensuring that users cannot access other parts of the le system.

4. In the NAS Volume Status panel, click the Snapshots & Clones tab.
The Snapshots list displays the snapshots.
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 le in the restored NAS volume will have the properties, such
as permission and time, that existed when you (or a schedule) created the snapshot.
Prerequisites
After you restore a NAS volume from a snapshot:
• The FluidFS cluster deletes any snapshots that were created after the snapshot from which you restored the NAS volume.
Snapshots created before the snapshot from which you restored the NAS volume are not aected.
• Current SMB clients of the NAS volume are automatically disconnected.
• Current NFS clients of the NAS volume receive stale NFS file handle error messages. You must unmount and then
remount the NFS exports.
CAUTION: The restore operation cannot be undone. Any data created or changed between the time of the snapshot and
when the restore operation is completed is permanently erased. You should restore a NAS volume from a snapshot only if
you rst understand all the repercussions of the restore operation.
Steps
1. In the Storage view, select a FluidFS cluster.
