Barracuda Backup

Site-to-Cloud Deployment

  • Last updated on

Barracuda Cloud Storage subscription plans provide diverse offsite storage that scales to meet your changing data requirements. Barracuda Cloud Storage includes secure backup to two separate data centers. Storage is allocated in 200 gigabyte increments and is all disk-based. The following image shows two Barracuda Backup appliances replicating data to Barracuda Cloud Storage:



Use the following steps to configure your Barracuda Backup appliance.

Create a Barracuda Cloud Control Account

You must have a Barracuda Cloud Control account to use Barracuda Backup. If you do not already have an account, follow these steps:

  1. Log in to https://login.barracuda.com.
  2. If you do not have an account, click Create a User, follow the account creation instructions, and log in.

Configure IP Address and Network Settings

By default, the Barracuda Backup appliance is configured to obtain an IP address on your network using DHCP. If you want to assign it a static IP address instead, you can configure it using the console administration interface. If not, skip the following steps:

To configure the Barracuda Backup appliance to use a static IP address:

  1. Connect a monitor and keyboard to the Barracuda Backup appliance.
  2. Use your arrow keys to highlight the DHCP/Static field.
  3. Using the spacebar select Static for your IP address assignment preference.
  4. Enter the IP Address, Netmask, Default Gateway, Primary DNS Server, and Secondary DNS Server (optional) as appropriate for your network.
  5. Click Enter on the Commit Changes box.

Once changes are committed, the Barracuda Backup appliance attempts to connect to Barracuda Networks.

The LAN and Internet boxes on the console administration interface are green when the Barracuda Backup appliance is determined to be online. The Barracuda box remains red until it is linked to an account later in the installation process.

Enter Encryption Key

This section only applies to the Barracuda Encrypted Backup appliance models 6090, 8090, 9090, and 10090. If you are not configuring an encrypted device, continue with Configure your Corporate Firewall.

  1. Use the Barracuda Console to access the configuration menu using the credentials admin / admin.
  2. Use the arrow keys to highlight Disk Encryption in the left pane.
  3. Press Enter to switch from read mode to edit mode.
  4. Use the arrow keys to highlight the Change Encryption Key section in the right pane.

     Use the arrow keys to navigate between the fields in the right pane.

  5. .Type a new encryption key that meets the password requirements listed on-screen in the Enter New Key and Confirm New Key fields.

    Important: The Barracuda Encrypted Backup appliance ships with a default security key. Once you enter a new encryption key, the key is known only to you; Barracuda cannot retrieve your key.

  6. Optionally, type a new power-on password in the Enter Password and Confirm Password fields.

    The power-on password is optional. If you select to use the power-on password, you are prompted to enter the password each time the appliance boots up.

  7. Navigate to Save, and press Enter. The confirmation screen displays.

  8. Press Enter to continue and return to the Barracuda Console.

  9. In the System Configuration screen, use the down arrow to navigate to and select Exit, and press Enter.

Configure Corporate Firewall

If the Barracuda Backup appliance is located behind a corporate firewall, you may need to open the following ports to allow communication between the Barracuda Backup appliance and the Internet.

  • Ports 80, 443, 1194, and 5120-5129 outbound for both TCP and UDP traffic. The ports are used to transfer data to either Barracuda Cloud Storage or to another Barracuda Backup appliance over the Internet. In site-to-site deployment, data can be replicated either over ports 5120-5129 or over a set of ports you specify on the Backup > Replication page.

    If you would like to restrict the outbound network traffic on these ports to Barracuda Cloud Storage, contact Barracuda Networks Technical Support for a list of the IP addresses to allow.

Activate Your Appliance

Your Barracuda Backup appliance must be linked to your Barracuda Cloud Control Account before you can initiate data backups. See the following articles for details on linking a Barracuda Backup appliance:

Add the Server Name and Location

Use the System > Barracuda Backup Appliance Settings page to view or modify the Barracuda Backup appliance details including name, time zone, physical location, and display group:

  • Barracuda Backup Appliance Name – Name used to identify the currently selected Barracuda Backup appliance in the web interface
  • Backup Appliance Time Zone – The time zone where the currently selected Barracuda Backup appliance is located
  • Barracuda Backup Appliance Location – The physical location of the Barracuda Backup appliance including city, state, and country
  • Barracuda Backup Appliance Display Group – The display group in which the Barracuda Backup appliance resides
    • Manage your display groups – Click to add or remove a display group in the Admin > Display Groups page
  • Backup Export Tool Settings – Set up the Backup Export Tool.

Define Display Groups (Optional)

If you have multiple Barracuda Backup appliances, you can manage them by creating display groups on the Admin > Display Groups page.

See the Display Groups Page for more information.


This section describes how to configure backups.

Add Systems and Select Data Sources

Set up your data sources on the Backup > Sources page, and specify that you want to Replicate to Barracuda Cloud Storage on the Add Data Source page. You may have more than one data source on each server, and each can have unique back up characteristics. For set up details by data source type, see Backup Up Data Sources

See Data Backup Tasks for more information.

Create Backup Schedules

Note that schedules are automatically created (with the default set to back up every day at 8:00PM) when a data source is created except if a schedule specifying all data sources already exists.

Now that you have configured your computers and data sources, you can create backup schedules, either individually or for all sources. If no schedule is created for a data source then it will not be backed up.

See the Schedules Page for more information.

Create Data Retention Policies

Data is retained based on a traditional grandfather-father-son (daily-weekly-monthly) rotation model. You can specify how long to keep daily, weekly, monthly, and yearly backups by creating data retention policies. Different retention policies can be created for different sets of data including files, data backed up by a Barracuda Backup Agent, and email messages.

You can create one policy for all of the computers and data sources on a Barracuda Backup appliance or multiple policies that each include some subset of the data.

Modify Your Backup Rate Limit (Optional)

Rate limits control the data replication rate to Barracuda Cloud Storage or other offsite storage locations. You can limit Internet bandwidth consumption during peak usage times, and schedule backups for non-peak hours.


See the Rate Limit Page for more information.

Exclude Files from a Backup (Optional)

You can create exclusion rules that use pattern matching to identify directory or file names that are not to be backed up. Files which are typically excluded from backups include temporary files, music, movies and other files which are not essential for business needs in the Backup > Exclusions page.

See the Exclusions Page for more information.

Check Backup Reports

View reports on an ongoing basis as needed. The Reports > Backup page contains detailed backup reports. A list of in progress backups displays at the top of the page, and once a backup is complete, a detailed report displays in a table by device. Click Details following the report you want to view.

See the Reports Page for more information.


This section describes how to secure your Barracuda Backup appliances.

Communication and Configuration

Administration and backup configuration that is set using the Barracuda Backup web interface is sent to the Barracuda Backup appliance via a 256-bit encrypted VPN tunnel. The Barracuda Backup appliance uses HTTPS port 1194 to send Status updates to Barracuda Backup. Data transfers are initiated by the Barracuda Backup appliance rather than by Barracuda Cloud Storage.

Data Transmission and Storage

Data transferred between your network and Barracuda Cloud Storage is always encrypted. File parts are AES 256-bit symmetrically encrypted before they are stored, and they remain encrypted until a restore is requested.

Management Access

  • Monitor Activity – You can check the user activity page periodically for authentication attempts, changes to settings, and updates to account information. Go to the Admin > User Activity Reports page to see all activity for an account, including logins and when a user has enabled or disabled replication.
  • Restrict Logins by IP Address – You can restrict access to Barracuda Backup to one or more IP addresses. On the Admin > Users page, click the Edit graphic (edit_icon.jpg) to edit a user account; enter an IP address or a range.
  • Secure Network Access – HTTPS is always used for secure web browser communication with Barracuda Backup.


Data transfers between the local Barracuda Backup appliance and a remote Barracuda Backup appliance are always encrypted. Data is stored compressed and encrypted at rest. Barracuda Backup utilizes an aggressive combination of symmetrical and asymmetrical encryption. The United States government recently approved 192-bit AES encryption as the preferred method for protecting top-secret information. The Barracuda Backup solution starts with even higher 256-bit AES encryption.

In addition, Barracuda Networks has developed a proprietary advanced digital cataloging system that breaks down your data into small pieces and tracks the changes of these parts over time, and strips the original meta identifiers from your files.

As data is transmitted to the remote Barracuda Backup appliance, your symmetrically-encrypted data parts are compressed and sent over your Internet connection with an asymmetrically-encrypted key.
