NetVault Backup Plug-in for NDMP 11.1 - Application Notes for NetApp ONTAP

Backing up data in C-mode

Starting with 10.0.5, NetVault Backup uses the CAB extension to perform backup and restore operations for cluster nodes running Data OnTAP 8.2.2 and later. The CAB extension enables the NDMP server to provide affinity information about volumes and tape devices to the backup application that support the CAB extension. NetVault Backup uses this affinity information to determine the data transfer path used during backup and restore operations. If a target volume and tape device are on same cluster node, a local backup or restore operation is performed; if they are on different cluster nodes, a three-way backup or restore operation is performed.

Restoring data

Restoring data using the plug-in

1
On the Create Restore Job — Choose Saveset page, the saveset table provides a list of available savesets.

Saveset is online (all segments are online).

Saveset is partially online (some segments are online).

Saveset is offline (all segments are offline).

Client

Displays savesets created for particular clients. The default selection is Any.

2
In the Choose Client dialog box, select the clients.

Plugin Type

Displays savesets created using a particular plug-in. The default selection is Any.

Date

Displays savesets created during a specified period. The default selection is Any.

Job

Displays savesets created for particular jobs. The default selection is Any.

2
In the Choose Job dialog box, select the jobs.
When you select a saveset, the following details are displayed in the Saveset Information area: job ID number, job title, tag, server name, client name, plug-in name, saveset date and time, retirement setting, Incremental Backup or not, archive or not, and saveset size.
4
On the Create Selection Set page, select the data that you want to restore:
Restore entire saveset: Select the root node.
Restore individual files and directories: Select the target files and directories in the selections tree. The selections tree can only be browsed if the Save File Information option was selected during backup.
If the backup contains a single file, the filename is added to the directory path. In the selection tree, it is displayed as /path/to/filename/filename and it is restored in that manner. The file is restored correctly if you select the directory and restore the file.
NOTE: While restoring data from a snapshot backup, you must use the Relocate option. If you do not use this option, the restore job fails. The Relocate option allows you to relocate data to the same or a different volume. For more information about relocating data, see Renaming or relocating data.

If you omit child-level items after selecting the parent node, the job fails. To perform selective restores, open the parent node, and select each item that you want to restore.
5
Click Edit Plugin Options, and configure the following settings.

NDMP Server

This option specifies the target filer name. It is only required when you want to restore data to an alternate filer. By default, it is set to the name of the original filer from which the data was backed up. Do not change the NDMP Server while restoring data to the same filer.

Direct Access Restore Mode

Select the appropriate Direct Access Restore (DAR) mode from the following:

Use Direct Access Restore if Possible: To perform a direct-access restore if the backup was direct and the mover and data server can complete a direct-access restore, select this option. If these conditions are not met, a nondirect-access restore is performed.
Use Direct Access Restore by Recovering Individual Files: To restore a directory and its file contents, select this option. When you use this option, empty directories in the saveset are ignored.
Only Do Direct Access Restore: To force a direct-access restore, select this option. It can be only used if the backup was direct and the mover and data server can complete a direct-access restore; otherwise the restore job fails.
Never Do Direct Access Restore: To perform a standard nondirect-access restore, select this option.

Incremental Restore

To recursively extract data and reconstruct the selected subtree to the state it was in at the time of backup, select this check box.

This option is equivalent to setting the environment variable EXTRACT=N. The plug-in overwrites the existing files and deletes the files that were not present at the time of backup.

Restore ACLs

To restore ACLs from the backed-up file, select this option. This option is equivalent to setting the environment variable EXTRACT_ACL=Y. You can use this option only if the Backup ACLs option was selected during backup.

IMPORTANT:

To save the settings, click OK, and then click Next.

In Job Name, specify a name for the job.
In the Target Client list, the client from which data was backed up is selected by default. Do not change this setting.
