Configuring general settings

This section includes the following topics:

•
Relocating default directories
•
Relocating the NetVault Database directory
•
Configuring TCP/IP buffer sizes
•
Changing language and locale settings
•
Changing locale settings for legacy clients
•
Disabling pre-installation package compatibility check
•
Configuring license expiration warning period

Relocating default directories

You can relocate database, trace, logs, reports, stats, and temporary directories to a different drive or volume to alleviate low disk space issues.

* 
NOTE: You must restart the NetVault Backup Service to apply any changes to these settings.
To relocate the default directories:
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 System and Security, click General. In the General dialog box, configure the following settings.

Description

Database Directory

This directory stores the module list, license keys, and NetVault Database.

The default path for the database directory is <NetVault Backup Home>\db on Windows and <NetVault Backup Home>/db on Linux.

For instructions on relocating the database directory, see Relocating the NetVault Database directory.

Trace Directory

This directory stores the NetVault Backup trace logs.

The default path for the trace directory is <NetVault Backup Home>\trace on Windows and <NetVault Backup Home>/trace on Linux. To relocate the directory, type the full path. The specified path must exist on the target drive or volume. If the NetVault Backup Server is unable to find the path, it fails to relocate the directory.

NOTE: The trace logs contain large volume of data. Therefore, this directory should not be relocated to a network share.

Log Directory

This directory stores the NetVault Backup log files.

The default path for the logs directory is <NetVault Backup Home>\logs on Windows and <NetVault Backup Home>/logs on Linux. To relocate the directory, type the full path. The specified path must exist on the target drive or volume. If the NetVault Backup Server is unable to find the path, it fails to relocate the directory.

Temporary Directory

This directory stores the temporary files generated during various NetVault Backup operations.

The default path for the temporary directory is <NetVault Backup Home>\tmp on Windows and <NetVault Backup Home>/tmp on Linux. To relocate the directory, type the full path. The specified path must exist on the target drive or volume. If the NetVault Backup Server is unable to find the path, it fails to relocate the directory.

NOTE: The temporary directory holds the Backup Saveset Index. The free disk space on this directory should be at least three times the size of the index file to perform backups and restores properly. For example, if the backup index file is 3GiB in size, the temporary directory should have at least 9GiB of free disk space. If the temporary directory does not have sufficient space, warnings and logs are generated.

Reports Directory

This directory stores the report templates.

The default path for the reports directory is <NetVault Backup Home>\reports on Windows and <NetVault Backup Home>/reports on Linux. To relocate the directory, type the full path.

Before configuring a new path, you must copy the directory contents to the new path. If a new path is configured without relocating the directory contents, an error message appears (“Provider 'NVBUPhysicalClient' failed”), and the NetVault Backup Service fails to restart.

Statistics Directory

This directory stores data collected by the nvstatsmngr process.

The default path for the statistics directory is <NetVault Backup Home>\stats on Windows and <NetVault Backup Home>/stats on Linux. To relocate the directory, type the full path. The specified path must exist on the target drive or volume. If the NetVault Backup Server is unable to find the path, it fails to relocate the directory.

Relocating the NetVault Database directory

To relocate the NetVault Database directory, use the procedures described in the following sections:

•
Changing the NetVault Database directory on a Linux-based machine
•
Changing the NetVault Database directory on a Windows‑based machine
Changing the NetVault Database directory on a Linux-based machine
To change the Database Directory on a Linux-based NetVault Backup Server:
1
Stop the NetVault Backup Service. You can use these steps:
a
In a terminal window, type txtconfig, and press Enter or Return.
b
On the Machine page, press p to view the main menu, and then press the option number for the Services page.
c
If the service is running, press the option number to stop the service.
2
Stop the netvault-pgsql service. You can use the following command:
/etc/init.d/netvault-pgsql stop
3
Manually move the db directory to the new location.
4
From the Txtconfig utility, change the Database Directory path. You can use the following steps:
a
On the Machine page, press p to view the main menu, and then press the option number for the General page.
b
Press the option number for the Database Directory setting, and type the full path.
The specified path must exist on the target drive or volume. If the NetVault Backup Server is unable to find the path, it fails to relocate the directory.
c
Press s to save the setting, and then press q to quit Txtconfig.
5
In the /etc/init.d/netvault-pgsql file, change the database path.
6
Change the file permissions and the owner and group for the new path:
chmod 700 <new DB path >
chown netvault-pgsql:netvault-pgsql <new DB path>
7
Start the netvault-pgsql service: /etc/init.d/netvault-pgsql start
8
Start the NetVault Backup Service.
Changing the NetVault Database directory on a Windows‑based machine
To change the Database Directory on a Windows-based NetVault Backup Server:
1
From the Configurator window, stop the NetVault Backup Service. (Click the Service tab, and then click Stop Service.)
2
From the Windows Services Management Console, stop the netvault-pgsql service.
3
Manually move the db directory to the new location. Make sure that the user under which the netvault‑pgsql service runs has the ownership of the new Database Directory.
4
On the Configurator window, click the General tab. In the Database Directory box, specify the full path.
The specified path must exist on the target drive or volume. If the NetVault Backup Server is unable to find the path, it fails to relocate the directory.
5
Open the Registry Editor.
6
Expand the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
netvault‑pgsql, and change the value for the ImagePath property to reflect the new path for the Database Directory.
7
On the Windows Services Management Console, right-click the netvault-pgsql service, and select Properties. On the General tab, verify that the Path to executable parameter displays the new database path.
8
Start the netvault-pgsql service.
9
From the Configurator window, start the NetVault Backup Service. (Click the Service tab, and then click Start Service.)

Configuring TCP/IP buffer sizes

In most cases, the default buffer sizes for the TCP/IP sockets are adequate, and should not be changed. For guidance on optimal buffer sizes and TCP/IP tuning, see your OS documentation.

To change buffer sizes for the TCP/IP sockets:
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 System and Security, click General. In the General dialog box, configure the following settings.
Setting
Description

Minimum network send buffer size

This setting determines the minimum send buffer size for a TCP/IP socket.

The default value is 1KB. To adjust the buffer size, type or select the new value. The buffer size must be set in KB.

This setting determines the maximum send buffer size for a TCP/IP socket.

The default value is 16384KB. To adjust the buffer size, type or select the new value. The buffer size must be set in KB.

Minimum network receive buffer size

This setting determines the minimum receive buffer size for a TCP/IP socket.

The default value is 1KB. To adjust the buffer size, type or select the new value. The buffer size must be set in KB.
