Administrator Guide

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.
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 affected.
• 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 first understand all the repercussions of the restore operation.
