NetVault Plug-in for NDMP 10.0.5 - User Guide

Configuring NetVault Backup user account

When backing up multiple volumes, the plug-in uses the “default” user account to run child jobs. If you assign a new password to this user account, you must also update the account details in the plug-in. Otherwise, the backup jobs that include multiple volumes report an error (“unable to log on to auditor, check account and password are valid”) and fail.
To configure password for the “default” user account
1
Start the Backup Job Wizard, and click Create New next to the Selections list.
2
Open the NetVault Backup Server, and then open NDMP Client.
3
Select the filer, and in the Actions list, click Set Account.
4
In the NetVault Account dialog box, provide the following information:
•
Account: Type “default”, which is the user account used to run the subjobs.
•
New Password: Select the New Password check box, and specify the password set for the “default” account.
5
Click OK to save the information.

Configuring default settings

The default settings apply globally to all NDMP Servers added to the plug-in.
To configure the default settings for Plug‑in for NDMP
1
Start the Backup Job Wizard, and click Create New next to the Selections list. Open the NetVault Backup Server. Select NDMP Client, and in the Actions list, click Configure.
— or —
In the Navigation pane, click Change Settings. On the Configuration page, click Server Settings, and then click Plugin Options.

Under NDMP Backup Log Filters, configure the following settings:
 
Table 2. NDMP backup log filters
Option
Description
Filter 1
Filter 2
...
Filter 10
You can use these settings to filter log messages generated during backup jobs. The messages that contain the strings specified in these boxes are not displayed on the View Logs page. Each box can contain one filter string. Thus, you can specify a maximum of 10 filter strings in the filter boxes.

Under NDMP Backup Configuration, configure the following settings.
 
Table 3. NDMP backup configuration
Option
Description
Maximum File Buffer Size
This setting can be used to increase the buffer size for file transfer to improve performance. The maximum buffer size value depends on the resources available on the NAS Filer. A large buffer size can have a negative impact on the data transfer and overall performance.
Maximum Index Buffer Size
This setting can be used to increase the buffer size for the transfer of backup index entries to improve performance. The maximum buffer size value depends on the resources available on the NAS Filer. A large buffer size can have a negative impact the data transfer and overall performance.
Codepage for UTF-8 Conversions
Type the codepage identifier for UTF-8 conversions. Use this option with the Use UTF-8 Conversions option described in the section Adding an NDMP Server.
Translations depend on the configuration, locale, and code sets installed on the system. For a list of codepage values, see the operating system documentation.
Use APM UTF-8 Conversion
To store and index UTF-8 character sets for browsing, select this check box. This setting allows you to browse the files in a native UTF supported language, such as Japanese. Without this setting, the plug-in indexes the files by filer‑specific NDMP metadata.
 
 
*NOTE: After configuring UTF-8 encoding setting on the filer, filer volumes, and plug-in, we recommend that you perform a test backup of some data on the relevant volumes. Then, browse these savesets using the Restore Job Wizard to ensure that the names of the directories and files are displayed correctly. This test is necessary because the UTF-8 name translations are received from the filer. If the filer fails to supply the names in UTF-8 format, it can cause corruption or truncation of the file and directory names.

Under NDMP Restore Log Filters, configure the following settings:
 
Table 4. NDMP restore log filters
Option
Description
Filter 1
Filter 2
...
Filter 10
You can use these settings to filter log messages generated during restore jobs. The messages that contain the strings specified in these boxes are not displayed on the View Logs page. Each box can contain one filter string. Thus, you can specify a maximum of 10 filter strings in the filter boxes.
Consider the following while configuring the filter expressions for NDMP restore logs:
•
When performing a restore, an error message is reported every time a file is overwritten. These errors can quickly add up to thousands of log messages, causing system degradation. The Filter 1 box contains a default expression “Warning: cannot create directory” that automatically blocks this type of error messages. We recommend that you do not change the default expression in the Filter 1 box.
•
By default, the text in Filter 1 appears in English regardless of the locale setting for NetVault Backup. This string should match the log messages that the NDMP Filer sends, indicating that it was unable to create a directory while performing a restore. If the filer log messages are in a language other than English, then the text in Filter 1 should be changed to match the message.
5
Click OK to save the settings and close the dialog box.

Configuring filer-attached devices

For administration of backups and restores to direct-attached devices, the device must be added to the NetVault Backup Server. For more information about adding storage devices to the NetVault Backup Server, see the Dell NetVault Backup Administrator’s Guide.
