default is 900 seconds (15 minutes). A smaller value results in greater accuracy.

Backing up and Restoring Hub Servers Manually
You may manually create a backup of your hub server. Two methods are available:
• From a command line in an MS-DOS window. This method may be used for DSView 3
software hub servers on supported Windows or Linux systems.
• Using the Backup and Restore Utility delivered with the DSView 3 software. The backup
is saved as a .zip file containing the files needed to restore the DSView 3 management
software. This method may be used for DSView 3 software hub servers on supported
Windows systems only.
Client sessions will be temporarily disconnected during a manual backup. The sessions will be
automatically reconnected when the backup is completed.
Hub server backups may also be automatically created as a task within the DSView 3 software.
If you use the Backup DSView database and system files task, client sessions will not be
temporarily disconnected. See Task: Backup DSView 3 software database and system files on
page 367.
Manual backup and restore procedures require DSView 3 software administrator privileges.
To manually backup or restore a hub server using a command line on a supported
Windows system:
1. In the Start menu on your desktop, select Start - Programs - Accessories - Command
Prompt. A command prompt window will open.
2. Change directories to the directory in which the DSView 3 software is installed (typically
C:\Program Files\Avocent DSView 3\bin).
3. Enter DSViewBackupRestore to display the DSView 3 Backup/Restore Utility dialog box.
Follow the directions in To manually back up a hub server using the Backup and Restore
Utility dialog box to back up the hub server using the dialog box or To manually restore a
hub server using the Backup and Restore Utility dialog box to restore the hub server using
the dialog box. (These procedures are described later in this section.)
