* 
NOTE: You must restart the NetVault Service to apply any changes to these settings.
To relocate the default directories:
1
In the Navigation pane, click Change Settings.
2
On the NetVault Server Settings page, complete one of of the following actions:
•
To configure default settings for the NetVault Server, continue to Step 3.
•
To configure default settings for a NetVault Client, click Clients. In the NetVault Clients table, select the client, and click Next.
3
Under System and Security, click General. In the General dialog box, configure the following settings.
 
Table 139. Default directory paths
Setting
Description

Database Directory

This directory stores the module list, licensefile or files, and NetVault Database.

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

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

Trace Directory

This directory stores the NetVault trace logs.

The default path for the trace directory is <NetVault Home>\trace on Windows and <NetVault 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 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 log files.

The default path for the logs directory is <NetVault Home>\logs on Windows and <NetVault 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 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 operations.

The default path for the temporary directory is <NetVault Home>\tmp on Windows and <NetVault 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 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 Home>\reports on Windows and <NetVault 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 Service fails to restart.

Statistics Directory

This directory stores data collected by the nvstatsmngr process.

The default path for the statistics directory is <NetVault Home>\stats on Windows and <NetVault 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 Server is unable to find the path, it fails to relocate the directory.
