How to Back Up and Restore Your System Configuration

  • Last updated on

You should back up your system regularly so, if necessary, you can restore your configuration on a Barracuda Link Balancer. To restore a backup file on a new Barracuda Link Balancer that is not configured, first enter the IP address and DNS information  for the new system on the BASIC > IP Configuration page.

Back Up Your System Configuration

This section describes how to create a single backup of the current system configuration and download the backup file (*.bak) to your local computerTo back up and restore the current system configuration of your Barracuda Link Balancer,

  1. Log into the Barracuda Link Balancer web interface.
  2. Go to the ADVANCED > Backups page.
  3. To back up the current system configuration, click Backup.

The following information is not included in the backup file:

  • System password
  • System IP information
  • DNS information

Configure Automatic Backups

  1. Log into the Barracuda Link Balancer web interface.
  2. Go to the ADVANCED > Backups page.
  3. In the  Automated Backups  section, s pecify the remote server that stores the backup files:
    1. From the Server Type list, select t he type of remote server that stores the backup files.
      • FTP An FTP server.
      • SMB A Windows shared drive on an SMB server.
    2. In the Server Name/IP field, enter t he server IP address or fully qualified domain name (FQDN). A FQDN consists of a host name and domain name, including the top-level domain.
    3. In the Port field, enter the  server port number to use.
      1. For an FTP server, the default port number is 21 .
      2. For an SMB server, the recommended port number depends on the version of the Windows® operating system running on the remote backup server.
      3. Port 139  is recommended for  Windows 3.x and  Windows NT Server 4.0.
      4. Port 445  is recommended for  Windows Server 2000,  Windows Server 2003 and  Windows XP.

    As a best practice, use a unique account for this integration point and grant it the least level of privileges required, coordinating with the FTP or SMB administrator. This account requires read and write privileges on the FTP or SMB server only for the specific path you indicate in the next field. For additional information, see Security for Integrating with Other Systems - Best Practices.
