What's New in Barracuda Backup

What's New in Version 6.5.00

Released September 18, 2018

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 recommends upgrading device firmware over a weekend or during a scheduled maintenance period.

The following enhancements have been added in Barracuda Backup 6.5.00:

  • 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
  • Improvements to support tunnel stability and user experience

The following issues have been resolved in Barracuda Backup 6.5.00:

  • [BNBS-36427] Hung VMware backup reports due to segfault in backup process
  • [BNBS-33520] Support tunnel incorrectly binding to incorrect port causing conflicts between processes
  • [BNBS-33655] Subscription expiration date on dashboard showing as "Invalid date"

  • [BNBS-29234] Slow load performance of VM list in Cloud LiveBoot VM selection dialog
  • [BNBS-30847] Restores of VMware VMs backed up on vSAN failing
  • [BNBS-24302] Network File Share backups can fail when encountering a single directory with a higher than average number of files and sub-directories
  • [BNBS-33690] User accounts fail to sync to the local Barracuda Backup device if notifications for that user are disabled
  • [BNBS-35491] Restores of offsite vaulted data can fail if first attempt at part retrieval fails (retry logic issue)
  • [BNBS-33577] VMware CBT backups not properly verifying the existence of previously backed up parts

  • {BNBS-16858] Hyperlinks to SQL databases in backup reports are not properly going to the object in the Restore Browser
  • [BNBS-37483] Slow performance when transferring statistical and report data used in the web UI
  • [BNBS-31140] The Current Tasks widget on the dashboard should not show Replication as "In Progress" if there is no binary data in the offsite transfer queue
  • [BNBS-33960] Unable to successfully link replacement devices when the option to migrate only the configuration is selected
  • [BNBS-35828] Invalid time zone of ' ' prevents backup jobs from running
  • [BNBS-31165] Backups failing when encountering nested volumes on btrfs filesystems
  • [BNBS-35313] Connection issues between ESXi host and Barracuda Backup during backup reads causing backups to fail in some cases
  • [BNBS-35906] Transfer graphs on dashboard not loading for AWS replication destinations

  • [BNBS-35411] Unable to remove offsite replication partners after a migration
  • [BNBS-35424] "Changed block tracking is not enabled" warning in backup reports used in cases where CBT cannot be used for different reasons or CBT is not being used at all

The following are known issues in Barracuda Backup 6.5.00:

  • [BNBS-37698] 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.)
