Upgrading to Veeam Backup for Microsoft Azure 5a
To perform upgrade of Veeam Backup for Microsoft Azure to version 5a, the backup appliance must be running version 3.0 or later. To upgrade from earlier versions, you must first perform update to Veeam Backup for Microsoft Azure version 3.0 or later as described in Installing Updates.
During upgrade to version 5a, the backup appliance operating system will be updated from Ubuntu 18.04 LTS to Ubuntu 22.04 LTS and the configuration database will be upgraded to PostgreSQL 15. The upgrade process requires certain actions carried out externally including re-deployment of the backup appliance on a new Azure VM and attachment of data disks from the previous backup appliance to this new Azure VM. That is why upgrade can be performed only using Microsoft Azure Plug-in for Veeam Backup & Replication. For more information on the upgrade procedure, its limitations and requirements, see the Integration with Veeam Backup & Replication Guide, section Upgrading to Veeam Backup for Microsoft Azure 5a.
Important |
Before you upgrade the backup appliance to version 5a, make sure all backup policies are disabled and no restore tasks are currently running. Otherwise, the upgrade process will interrupt the running activities, which may result in data loss. |
To upgrade the backup appliance, do the following:
- Install Microsoft Azure Plug-in for Veeam Backup & Replication as described in the Integration with Veeam Backup & Replication Guide, section Deployment.
Tip |
If you do not have a valid Veeam Backup & Replication license, you can download a 30-day trial version of the product. |
- Add the backup appliance to the Veeam Backup & Replication infrastructure as described in the Integration with Veeam Backup & Replication Guide, section Connecting to Existing Veeam Backup for Microsoft Azure Appliances.
When connecting to the backup appliance, Veeam Backup & Replication will display a warning notifying you that the appliance must be upgraded. Acknowledge the warning to allow Veeam Backup & Replication to automatically upgrade the appliance to the necessary version.
Note |
When you connect the backup appliance to the Veeam Backup & Replication infrastructure, the license installed on the appliance becomes invalid. Protected instances start consuming license units from the license installed on the Veeam Backup & Replication server. However, as soon as you remove the backup appliance from the Veeam Backup & Replication infrastructure, Veeam Backup for Microsoft Azure will continue using the license that had been used before you added the Veeam Backup for Microsoft Azure appliance to the Veeam Backup & Replication infrastructure. For more information on licensing scenarios, see Integration with Veeam Backup & Replication Guide, section Licensing. |
- [This step applies only if the backup appliance has not been upgraded at step 2] Upgrade the backup appliance as described in the Integration with Veeam Backup & Replication Guide, section Upgrading Appliances.
- After the upgrade process completes, you can remove the backup appliance from the Veeam Backup & Replication infrastructure, as described in the Integration with Veeam Backup & Replication Guide, section Removing Appliances, if you do not plan to further manage this appliance from the Veeam Backup & Replication console.
Make sure to remove the appliance from the Veeam Backup & Replication infrastructure before you uninstall Veeam Backup & Replication. Otherwise, Veeam Backup for Microsoft Azure will not be able to perform backup and restore operations due to the licensing issues.
- Uninstall Veeam Backup & Replication if you no longer need it, as described in the Veeam Backup & Replication Guide, section Uninstalling Veeam Backup & Replication. In this case, Microsoft Azure Plug-in for Veeam Backup & Replication will be removed as well.
