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 computer . To 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

To schedule automated backups of the current system configuration, use the Automated Backups section. Store the backup files on a  remote server . 

  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.
  4. Enter the  Username and Password for user authentication on the FTP or SMB server.
    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.

  5. In the Folder/Path field, enter t he folder, path, or share name of the location on the FTP or SMB server that stores the backup files.

    You should click Test Backup Server to verify that the remote server is capable of storing backup files.

  6. Select the box next to System Configuration  to schedule the backup and  select a day of the week (or Daily) and the time of day to perform backup.
  7. In the Backups to Keep  field, specify the maximum number of backup files to keep on the remote server.
  8. Click Save Changes  to schedule the backup.

Restore Your System Configuration

Before restoring the contents of an automatic backup file, verify the Automated Backups section to ensure the remote server is working and reachable and click Test Backup Server.

  1. Click Browse to open the file location or Browse Auto Backups window.
  2. Specify the backup file to be retrieved and restored, and select it.
  3. Click Upload.
  4. To restore the selected backup file, click Apply Now.
