Requirements

To upgrade to Veeam Backup for Nutanix AHV 3a, download the installer below and run it on the Veeam Backup & Replication server that manages the AHV Backup Proxy(s).

If you are upgrading from a version prior to Veeam Backup for Nutanix AHV 3, please carefully review the upgrade checklist section of the Veeam Backup for Nutanix AHV User Guide.

 

You can check the AHV Backup Proxy Version by clicking the gear icon at the top-right corner of the AHV Backup Proxy web console and selecting the Appliance Settings tab.

After updating to Veeam Backup for Nutanix AHV 3a, the AHV Backup Proxy Appliance version number will be 3.1.36.

Veeam Backup for Nutanix AHV 3a only supports integration with Veeam Backup & Replication version 11a or later.

What's New

  • Appliance Performance: Reduced the amount of session information retained, which reduces process delays and hangs. A new parameter to adjust session retention time was implemented. The parameter can be changed via  SessionManager.SessionHistoryRetentionDays in /opt/VeeamBackupAgent/appsettings.json on the proxy appliance.
    • Newly deployed AHV Proxy Appliances will retain session information for 13 weeks (new default).
    • Existing AHV Proxy Appliances will continue to retain 53 weeks (old default) after the upgrade.

Resolved Issues

  • Corrected job status reporting so that Veeam ONE job reports correctly display policy sessions as having a "Completed" state with a valid EndTime if the policy is not "Running".
  • PD-snapshot policy fails with the error “Value cannot be null. Parameter name: key”.
  • Backup policy fails with the error “Failed to start a backup process: Policy session with tag {tag} is already finished”.
  • CBT tag missing if the AHV backup policy fails during the backup process.
  • AHV Proxy will now correctly clean up connected SCSI devices.
  • Long query times to the AHV proxy database, resulting in reduced performance.
  • Corruption of appsettings.json file after restarting the Proxy service.
  • VeeamZIP job fails with error “Cannot find repository {uuid}
  • Scheduler ignoring an active full backup request and creating an incremental backup instead.

Security Improvements

  • Authentication mechanisms were improved.
  • REST API security was improved.
  • SMTP certificate validation improved.
  • Third-party libraries were upgraded.

Known Issues

  • If a VPC/overlay subnet is present on the cluster and used by a VM, the network information will be skipped when the VM is backed up. Such VM will be restored without a connected network adapter.
  • Due to improved security checks, the web console will not permit login if the account contains a special character, for example, an '@" symbol. If the local account on the AHV Proxy Appliance was created containing an '@' symbol, please contact support for assistance with creating a new local account that does not contain a special character.
    As documented in the user guide, the AHV Proxy Appliance does not integrate with Active Directory.
