NetVault 12.2 - Administration Guide

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:

In the Navigation pane, click Change Settings.

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.

Under System and Security, click General. In the General dialog box, configure the following settings.

Table 135. Default directory paths
Setting	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:

Stop the NetVault Backup Service.

•

If the systemd is supported on the system:

Run the systemctl stop netvault command.

•

If the systemd is not supported on the system:

In a terminal window, type txtconfig, and press Enter or Return.

On the Machine page, press p to view the main menu, and then press the option number for the Services page.

If the service is running, press the option number to stop the service.

Stop the netvault-pgsql service.

•

If the systemd is supported on the system:

Run the systemctl stop netvault-pgsql command.

•

If the systemd is not supported on the system:

Run the /etc/init.d/netvault-pgsql stop command

Manually move the db directory to the new location.

From the Txtconfig utility, change the Database Directory path.

On the Machine page, press p to view the main menu, and then press the option number for the General page.

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.

Press s to save the setting, and then press q to quit Txtconfig.

In the NetVault Backup installation directory, open the config directory, and then open the pgdb.cfg configuration file in the text editor.

In the [InstallInfo] section, change the datadir to specify new path for pgsql.

datadir=<new db path>/pgsql

Change the database path from the service script:

•

/etc/init.d/netvault-pgsql file.

•

/usr/lib/systemd/system/netvault-pgsql.service file.

Change the file permissions of the owner and group for pgsql directory from the new path:

chmod 700 <new DB path>/pgsql

chown netvault-pgsql:netvault-pgsql <new DB path>/pgsql

Start the netvault-pgsql service.

•

If the systemd is supported on the system:

Run the systemctl start netvault-pgsql command.

•

If the systemd is not supported on the system:

Run the /etc/init.d/netvault-pgsql start command

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:

From the Windows Services Management Console, stop the netvault-pgsql service and NetVault Process Manager service.

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.

In the NetVault Backup installation directory, open the config directory, and then open the file configure.cfg in a text editor.

In the [Directories:Database] section, change the Value to specify the full path.

Value=<full path>

In the NetVault Backup installation directory, open the config directory, and then open the pgdb.cfg file in the text editor.

In the [InstallInfo] section, change the datadir to specify new path for pgsql.

datadir=<new db path>\pgsql

Open the Registry Editor.

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.

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.

Start the netvault-pgsql and NetVault Process Manager service.

Configuring TCP/IP buffer sizes
