Backing Up and Restoring NAS File Servers Using Tivoli Data Protection for NDMP

After you have completed the steps in Configuring Tivoli Data Protection for NDMP, you are ready for NDMP operations. Use either a client interface or an administrative interface described in Interfaces Used for Tivoli Data Protection for NDMP to perform a file system image backup. For example, to use the Windows NT backup-archive client interface to back up a file system named /vol/vol1 on a NAS file server named NAS1, enter the following command:

dsmc backup nas -nasnodename=nas1 {/vol/vol1} 

For more information on the command, see Tivoli Storage Manager for Windows Backup-Archive Installation and User's Guide or Tivoli Storage Manager for UNIX Backup-Archive Installation and User's Guide.

Note:
Whenever you use the client interface, you are asked to authenticate yourself as a Tivoli Storage Manager administrator before the operation can begin. The administrator ID must have at least client owner authority for the NAS node.

You can perform the same backup operation with a server interface. For example, from the administrative command-line client, back up the file system named /vol/vol1 on a NAS file server named NAS1, by entering the following command:

backup node nas1 /vol/vol1

You can restore the image using either interface. Backups are identical whether they are backed up by using a client interface or a server interface. For example, suppose you want to restore the image backed up in the previous examples. For this example the file system named /vol/vol1 is being restored to /vol/vol2. Restore the file system with the following command, issued from a Windows backup-archive client interface:

dsmc restore nas -nasnodename=nas1 {/vol/vol1} {/vol/vol2}

You can choose to restore the file system by using a server interface. For example, to restore the file system name /vol/vol1 to file system /vol/vol2, for a NAS file server named NAS1, enter the following command:

restore node nas1 /vol/vol1 /vol/vol2
