Configuration Backup And Restore; Backing Up The Entire System - D-Link NetDefend DFL-210 User Manual

2.6.3. Configuration Backup and
Restore
snapshot of the state on November 21st, 2008.
To restore a backup file, the administrator should upload the file to the D-Link Firewall. The name
of the file does not need to be changed in any way and can retain the date since NetDefendOS will
read a header in the file to determine what it is.
Backup and Restore using the WebUI
As an alternative to using SCP, the administrator can initiate a backup or restore of the configuration
or complete system directly through the WebUI. The example below illustrates how this is done.
Example 2.15. Backing up the Entire System
In this example we will backup the entire system on 12 December 2008.
Web Interface
1. Go to Maintenance > Backup
2. The Backup dialog will be shown
3. Press the Backup configuration button
4. A file dialog is shown - choose a directory for the created file
5. Download of the backup file will then start

2.6.3. Configuration Backup and Restore

The NetDefendOS configuration of a D-Link Firewall at any given point of time can be backed up
or restored on demand. Configurations are downloaded through the WebUI to a single file which is
saved on the local management workstation. This file can then be uploaded at any time restore that
configuration.
By default, backup files have the filetype .pkg and the file name is of the form config-yyyymmdd.pkg
where "yyyymmdd" represents the date of the backup. A backup created on December 21st, 2008
would therefore be called config-20081221.pkg.
Backups can be created at any time without disturbing NetDefendOS operation. After restoring a
backup it is necessary to perform an Activate to make the configuration active. This activation
should, in most cases, not disturb system operation.
Example 2.16. Configuration Backup and Restore
Web Interface
To create a backup of the currently running configuration:
1. Go to Tools > Backup
2. Download configuration, select a file name and begin the backup
To restore a configuration backup:
Note: Backups do not contain everything
Backups include only static information from the NetDefendOS configuration.
Dynamic information such as the DHCP server lease database or Anti-Virus/IDP
databases will not be backed up.
