Tivoli Storage Manager supports backup and restore of network attached storage (NAS) file system images to tape drives or libraries that are locally attached to NAS file servers. Tivoli Data Protection for NDMP enables backup and restore support on the Tivoli Storage Manager Windows NT and Windows 2000 servers for NAS file servers from Network Appliance. Tivoli Data Protection for NDMP is a separately priced and licensed product.
For information on how to configure Tivoli Data Protection for NDMP on the Tivoli Storage Manager server, see Tivoli Storage Manager for Windows Administrator's Guide, GC35-0410.
See "Tivoli Data Protection for NDMP Version 4.2.1 Requirements" for client and server hardware and software requirements.
After configuring Tivoli Data Protection for NDMP, the server connects to the NAS device and uses NDMP to initiate, control, and monitor each backup and restore operation. The NAS device performs outboard data transfer to and from the NAS file system to a locally attached tape drive or library.
It is not necessary for a client node to mount a NAS file system to perform backup or restore operations on that file system.
The benefits of performing backups using Tivoli Data Protection for NDMP include the following:
The following support is provided:
The following functions are not supported:
For information on how to install and configure the Web client, see "Installing and Using the Web Client".
For both the Web GUI and the command line client, you must specify passwordaccess=generate (which is a current web client restriction for the client node) and the authentication=on must be specified at the server. You are always prompted for a user ID and password. To display NAS nodes and perform NAS functions, you must enter an authorized administrative user ID and password. The authorized administrative user ID should have at least client owner authority over both the NAS node and the client workstation node they are using either from command line or from the web.

Table 32 lists the commands and options you can use to back up NAS
file system images from the command line.
Table 32. NAS Options and Commands
Option or Command | Definition | Page |
---|---|---|
domain.nas | Specifies the volumes to include in your default domain for NAS backups. | Domain.nas |
exclude.fs.nas | Excludes file systems on the NAS file server from an image backup when used with the backup nas command. This option is for Windows NT and Windows 2000 clients only. | Exclude Options |
include.fs.nas | Includes a file system or assigns a management class when used with the backup nas command. This option is for Windows NT and Windows 2000 clients only. | Include Options |
query node | Displays all the nodes for which a particular administrative user ID has authority to perform operations. The authorized administrative user ID should have at least client owner authority over both the NAS node and the client workstation node they are using either from command line or from the web. | Query Node |
backup nas | Creates an image backup of one or more file systems that belong to a Network Attached Storage (NAS) file server. | Backup NAS |
monitor process | Displays current back up and restore processes for all NAS nodes for which an administrative user has authority. The administrative user can then select one process to monitor. | Monitor Process |
cancel process | Displays current back up and restore processes for all NAS nodes for which an administrative user has authority. From the display, the administrative user can select one process to cancel. | Cancel Process |
query backup | Use the query backup command with the class option to display information about file system images backed up for a NAS file server. | Query Backup |
query filespace | Use the query filespace command with the class option to display a list of file spaces belonging to a NAS node. | Query Filespace |
delete filespace | Use the delete filespace with the class option to display a list of file spaces belonging to a NAS node so that you may choose one to delete. | Delete Filespace |
A NAS file system specification uses the following conventions:
You can restore full or differential NAS file system images that were backed up previously. If you restore a differential image, Tivoli Storage Manager automatically restores the full backup image first, followed by the differential image. It is not necessary for a client node to mount a NAS file system to perform backup or restore operations on that file system.
