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.
Prerequisite
After you restore a NAS volume from a snapshot:
• The FluidFS cluster deletes any snapshots 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.
