NetVault 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.

* 
NOTE: During an NDMP backup or restore using the CAB extension, if a fail-over occurs, the job continues without any interruption. After the fail-over, if the volume is moved to a different node, the data transfer path may change depending on the affinity information provided by NetApp.
To back up one or more volumes in C-mode:
1
In the Navigation pane, click Create Backup Job.
— or —
In the Navigation pane, click Guided Configuration, and then on the NetVault Configuration Wizard page, click Create Backup Jobs.
2
In Job Name, specify a name for the job.
Assign a descriptive name that lets you easily identify the job for monitoring its progress or restoring data. The job name can contain alphanumeric and nonalphanumeric characters, but it cannot contain non-Latin characters. There is no length restriction. However, a maximum of 40 characters is recommended on all platforms.

Use the following format to specify the backup path:
/<vserverName>/<volumeName>/.snapshot/<snapshotName>
Example:
/vs1/vol2/.snapshot/daily.2014-06-16_0010

Restoring data using the plug-in

1
In the Navigation pane, click Create Restore Job.
On the Create Restore Job — Choose Saveset page, the saveset table provides a list of available savesets.
The table shows the saveset name (Job Title and Saveset ID), creation date and time, saveset size, and saveset status. The saveset status is indicated using the following icons.
Icon
Description

Saveset is online (all segments are online).

Saveset is partially online (some segments are online).

Saveset is offline (all segments are offline).

The saveset list is sorted by creation date (newest to oldest). You can sort the list by one or more columns, as required. The arrowhead next to the column name indicates the sort order.
2
To filter the saveset list, use the following filter options.
Filter
Description

Client

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

1
To use this filter, click the Client box.
2
In the Choose Client dialog box, select the clients.
3
To close the dialog box, click OK.

Plugin Type

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

1
To use this filter, click the Plugin Type box.
2
In the list, select the plug-in.

Date

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

1
To use this filter, click the Date box.
2
In the list, select the option that you want to use.
The available options are Last 24 hours, Last Week, Last Month, Last 6 Months, Last Year, and Any.

Job

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

1
To use this filter, click the Job box.
2
In the Choose Job dialog box, select the jobs.
3
To close the dialog box, click OK.
3
Select the saveset that you want to use, and click Next.
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.
Table 4. Restore options
Option
Description

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.
You must select this option if any item was omitted during data selection; otherwise, the restore job fails.
•
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:  
•
When individual files are selected for DAR, their parent-level directory permissions are not restored.
•
When running DAR, NetVault Backup organizes the restore requests into groups of 1024 files at a time. When a restore job consists of more than 1024 total files, multiple restore requests are issued. So, multiple log entries are displayed for the job.
6
To save the settings, click OK, and then click Next.
7
In Job Name, specify a name for the job.
Assign a descriptive name that lets you easily identify the job for monitoring its progress. The job name can contain alphanumeric and nonalphanumeric characters, but it cannot contain non-Latin characters. There is no length restriction. However, a maximum of 40 characters is recommended on all platforms
In the Target Client list, the client from which data was backed up is selected by default. Do not change this setting.
8
Select or create the Schedule Set, Restore Source Set, and Advanced Options Set.
For more information about these sets, see the Quest NetVault Backup Administrator’s Guide.
9
To submit the job for scheduling, click Submit.
You can monitor the job progress from the Job Status page and view the logs from the View Logs page. For more information about these functions, see the Quest NetVault Backup Administrator’s Guide.
