Other configuration utilities

You can also use the Txtconfig utility to customize default settings for the server and client machines.

Txtconfig

The Txtconfig utility provides a text-based interface to customize various settings for the server and client machines. This utility is available on all supported operating systems. The Txtconfig utility resides in the bin directory under the NetVault Backup installation directory. You must be logged-in with Administrator privileges on Windows and root user privileges on Linux and UNIX to use the Txtconfig utility. For more information, see Configuring default settings using Txtconfig.

Configuring encryption settings

Before you can start using the Plug-in for Standard Encryption or Plug-in for Advanced Encryption, you must configure the encryption settings, which specify the encryption algorithm and encryption key that you want to use. You can configure these settings from the Change Settings link.

The encryption plug-ins provide support for CAST-128, AES-256, and CAST-256 algorithms to meet regulatory backup security requirements. You can install these plug-ins on the NetVault Backup Server or Clients to perform encrypted backups for that machine. For more information about these plug-ins, see the Quest NetVault Backup Plug-in for Standard Encryption User’s Guide or Quest NetVault Backup Plug-in for Advanced Encryption User’s Guide.

To configure default settings for the encryption plug-ins:
1
In the Navigation pane, click Change Settings.
2
To configure default settings for the NetVault Backup Server, click Server Settings.
— or —
To configure default settings for a NetVault Backup Client, click Client Settings. In the NetVault Backup Clients table, select the client, and click Next.
3
Under Plugins, click Encryption, and configure the following settings.
 
Table 125. Default settings for encryption plug-ins
Setting
Description

Encrypt ALL Backups on this Client

Once the Plug-in for Standard Encryption or Plug-in for Advanced Encryption is installed on a client, you can do either of the following:

•
Encrypt all backups performed for that client
•
Encrypt specific backups performed for that client

To enable encryption for all backups, select this check box. When you enable encryption for all backups, you cannot change the setting on a per-job basis.

For more information about performing job-level encryption, see Specifying additional options.

NOTE: To perform job-level encryption for backups originating from a NetVault Backup Server or Client, the plug-in should not be configured for encrypting all backups.

Encryption Key String

Type the string that serves as the encryption key for the NetVault Backup machine.

Different platforms allow varying characters and password lengths. We recommend that you use passwords of 32 characters or less. You can use characters from the following set: “A–Z”, “a–z”, “0–9”, and “_”. Key strings that do not conform to these specifications may work on one platform, but may be invalid in another environment.

Available Encryption Algorithms

Select the encryption algorithm that you want to use for backups and restores. Depending on the products that you have installed, the list includes the following options: CAST-128, CAST-256, and AES-256.

Click Apply to apply the new settings and close the dialog box.
 
* 
NOTE: An encrypted backup can be restored to the original client or an alternate client. In both cases, the plug-in must be installed on the target client and it must be configured as it was when the backup was performed — using the same Encryption Key String and Encryption Algorithm.

Configuring plug-in options

Configuring plug‑in options

You can configure default settings for various built-in and licensed plug-ins from the Change Settings or Create Backup Job page. The plug-in configuration procedures are covered in the respective user guides.

This section includes the following topics:

•

Configuring default settings for Disk Devices Plug-in

Configuring default settings for Disk Devices Plug‑in

The Disk Devices Plug-in is used to create Virtual Tape Libraries (VTLs). You can configure default settings for this plug-in from the Change Settings page.

To configure default settings for the Disk Devices Plug-in:
1
In the Navigation pane, click Change Settings.
2
To configure default settings for the NetVault Backup Server, click Server Settings.
— or —
To configure default settings for a NetVault Backup Client, click Client Settings. In the NetVault Backup Clients table, select the client, and click Next.
3
Under Plugins, click Plugin Options. In the Plugin Options dialog box, under Disk Devices Plugin, configure the following options.
 
Table 126. Default settings for Disk Devices Plug-in
Setting
Description

Allow disk libraries to have entry/exit ports

Virtual tape libraries do not have an entry/exit port by default.

To create Virtual Tape libraries that have entry/exit ports (EEPorts), select this check box.

Check available disk space before creating disk libraries

This check box is selected by default.

Before creating a VTL, NetVault Backup performs a disk space check to ensure that the target disk has sufficient space to accommodate the new VTL. On normal file systems you can use this feature to avoid errors during VTL creation.

When creating a VTL on a third-party deduplication appliance or compressed file system, you should disable this feature. To disable disk space checks for VTLs, clear this check box.

Free disk space margin to be used when calculating available disk space

During disk space checks, the free space required on the disk is calculated as follows:

Number of Slots * Media Capacity + <x>

<x> is the additional disk space considered for the following requirements:

•
Disk space required to create the directory structure for the VTL. This requirement varies for different file systems.
•
Disk space required by other applications running on the system.

The default value is 20MB. To change this requirement, type or select the new value.

Unit used to express the free disk space margin in

Type or select the unit used to specify disk space margin. The unit can be MB or GB. The default unit is MB.
