Option 2 – Restore Files Using Windows Only
Snapshots integrate into the Shadow Copies and previous versions features of Windows. This restore option allows clients to restore a file
using previous versions.
Steps
1. Right-click the file and then select Properties.
2. Click the Previous Versions tab.
A list displays the available previous versions of the file.
3. Select the version to restore and then click Restore.
Disabling Self-Restore
Steps
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. Click Edit Settings.
The Edit NAS Volume Settings dialog box opens.
5. Click Data Protection.
6. To allow or prevent user access to snapshot content:
• To allow user access to snapshot content, select the Access to Snapshot Contents checkbox.
• To prevent user access to snapshot content, clear the Access to Snapshot Content checkbox.
7. Click OK.
Managing NDMP
The FluidFS cluster supports Network Data Management Protocol (NDMP), which is an open standard protocol that facilitates backup
operations for network attached storage, including FluidFS cluster NAS volumes. NDMP should be used for longer-term data protection,
such as weekly backups with long retention periods.
The FluidFS cluster supports remote and three-way backup architecture implementations, wherein a supported, external Data
Management Application (DMA) server mediates the data transfer between the FluidFS cluster and the storage device. The FluidFS
cluster supports full, differential, and incremental NDMP Level Based Backup (levels 0-9), Full, Incremental/Differential Token Based
Backup, and Direct Access Recovery (DAR). The FluidFS cluster supports NDMP versions 3 and 4 (default mode).
The FluidFS cluster includes an NDMP server that is responsible for the following operations:
• Processing all NDMP backup and restore requests sent from DMA servers
• Sending all NDMP replies and notification messages to DMA servers
• Transferring data over the network to or from remote NDMP tape or data servers
The NDMP server handles all communications with the DMA servers and other NDMP devices through an XDR encoded TCP
(Transmission Control Protocol) data stream.
The NDMP server supports two backup types:
• dump: Generates inode-based NDMP file history
• tar: Generates path-based NDMP file history
The backup type is controlled by the NDMP environment variable TYPE. Both backup types support the same functionalities, but the tar
backup type might be able to process the information more efficiently for certain DMA servers.
