What's New in Barracuda Backup

Last updated on 2023-06-15 19:27:07

What's New in Version 6.6.04

Early Availability Release Date: December 6, 2022

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 6.6.04 includes a kernel update, which will require a reboot of this Barracuda Backup device. Before updating the device firmware to 6.6.04, 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 6.6.04 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.

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.

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.

Enhancements

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]

What's New in Version 6.4.07

Released October 30, 2018

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

Please be advised that the firmware upgrade to 6.4.07 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 2^nd 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.
