What's New in Barracuda Backup

  • Last updated on

What's New in Version 6.6.05

Early Availability Release Date: August 27, 2024

Note: For the best experience, all devices attached to an account or replicating site-to-site should be updated to the same firmware version.


Important:

  • To prevent issues during the upgrade process, firmware upgrades have been disabled for customers with appliance serial numbers below 800000. For more details, contact Barracuda Networks Technical Support.
  • This release does not support locally controlled Barracuda Backup devices. The current Local Control release for Barracuda Backup is firmware version 6.4.03.

Please be advised that if you are updating from a firmware version prior to 6.5.04, the firmware update to 6.6.05 includes a kernel update, which will require a reboot of this Barracuda Backup device. Before updating the device firmware to 6.6.05, it is recommended that you have physical access to the device in the event of a failure. The kernel update will occur first, followed by a system reboot, then the completion of the firmware update when the device comes back online. The entire 6.6.05 firmware update process may take 30-60 minutes to complete. After the update, the next scheduled backup will undergo a one-time data verification check that may cause increased backup windows.

The 6.5.01 early availability release has been merged into 6.5.02.

Please be advised that the firmware update to 6.5.02 includes a kernel update, which will require a reboot of this Barracuda Backup device. Before updating the device firmware to 6.5.02, it is recommended that you have physical access to the device in the event of a failure. The kernel update will occur first, followed by a system reboot, then the completion of the firmware update when the device comes back online. The entire 6.5.02 firmware update process may take 30-60 minutes to complete. After the update, the next scheduled backup will undergo a one-time data verification check that may cause increased backup windows.

Enhancements
  • Extended Microsoft Platform Support
    • Barracuda Networks has added official support for the following Microsoft platforms:
      • Microsoft Windows Server 2019
      • Microsoft Hyper-V Server 2019
      • Microsoft SQL Server 2019
  • Improved Barracuda Backup Agent Security
    • The Barracuda Backup Agent now uses TLS 1.2 (128-bit AES) to both authenticate with a Barracuda Backup device and encrypt the connection between the Barracuda Backup Agent and the Barracuda Backup device. This enhancement provides secure encrypted communication and helps prevent potential man-in-the-middle attacks.
  • Expanded Configuration Options with Static Routes
    • Static routes can now be configured from the Barracuda Backup cloud interface. Static routes are used to connect the Barracuda Backup device to a specific network or sub-network in cases where the routing is not happening automatically.
  • Enhanced Bare Metal Recovery for Microsoft Windows
    • The new bare metal recovery (BMR) kit creates a bootable ISO using the latest Windows ADK (Windows Assessment and Deployment Kit) and WinPE (Windows Preinstallation Environment) add-on from Microsoft. This provides the latest software from Microsoft, improving reliability.
Fixes
  • If the Barracuda Backup device loses NTP synchronization during a backup, the backup reports as failed immediately, when it should wait until the backup has finished. [BNBS-37639]
  • Failed backup reports will show an error header that states the number of issues in the backup, but no details for the errors are shown in the report. [BNBS-31178]
  • The Barracuda Backup Agent for MacOS fails to backup data underneath a directory when that directory returns a “no data available” error code during a backup. [BNBS-37783]
  • When clicking on the purge button on the Large Items page, there is no warning notification about purging/deleting data. [BNBS-32680]

  • When using LiveBoot, some errors can leave a back trace on the page. [BNBS-31134]
  • The data migration options (hardware replacements) page is showing "Migrate from Barracuda Cloud" for devices that have been replicated to AWS. [BNBS-37710]
  • Restore actions on a privately encrypted receiver will always prompt for the LOCAL passphrase regardless of whether the data would require it or if the passphrase is correct. [BNBS-37725]

    • Workaround: Contact Barracuda Networks Technical Support for resolution, patch available for firmware version 6.5.02.
  • Complete file system restore of a Windows Server 2019 system to the original location will result in a failure to restore the Windows Defender directories and contents located in C:\ProgramData and C:\Program Files. [BNBS-41652]
    • Workaround: Windows Defender directories and contents can be downloaded or restored to an alternate location. The directories can also be recovered by performing a Windows Bare Metal Recovery.
  • A complete system state restore of a Windows Server 2019 system will fail due to the Windows Defender directories and files. [BNBS-41655]
    • Workaround: The entire Windows Server 2019 system can be recovered by performing a Windows Bare Metal Recovery.

What's New in Version 6.5.00

Released September 18, 2018

Note: For the best experience, upgrade all devices attached to an account or replicating site-to-site to the same firmware version.

Important: This release does not support locally controlled Barracuda Backup devices. The current Local Control release for Barracuda Backup is firmware version 6.4.03.

Be advised that the firmware upgrade to 6.5.00 from any version prior to 6.4.06 requires all data sources protected using the Barracuda Backup Agent to undergo a data verification check, known internally as a second-pass backup, on the next scheduled backup. The one-time data verification check will cause increased backup windows. For this reason, Barracuda Networks recommends upgrading device firmware over a weekend or during a scheduled maintenance period.

  • Private encryption of cloud data
  • Automated migration option for cloud data and configuration
  • Barracuda Backup Agent security enhancements
  • Enhanced single file downloads to support browser restart capability

  • Restores from replication partners may fail if parts are not present locally. (When data is sent to both a cloud destination and another Barracuda Backup device, Barracuda will attempt to pull file parts from the cloud if they cannot be found on the Barracuda Backup replication partner during a restore job. If private encryption of cloud data is configured for the cloud target, the restore will fail as the parts are privately encrypted.) [BNBS-37698]    
  • Writing more than 4TB to BET fails for removable drives. This issue exists in previous versions and is included in Barracuda Backup 6.5.01. [BNBS-37680]
