Eliminating Warnings

If Veeam Backup & Replication encounters an issue while verifying the connection to the specified Veeam Backup for AWS appliance, you may get one of the following warnings.

Version Compatibility Alert

If you try to add to the backup infrastructure an appliance that runs a version of Veeam Backup for AWS that is not compatible with the version of Veeam Backup & Replication, Veeam Backup & Replication will display a warning notifying that the appliance must be upgraded. To eliminate the warning, click Yes. Veeam Backup & Replication will automatically upgrade the appliance to the necessary version.

Certificate Security Alert

When you add a Veeam Backup for AWS appliance to the backup infrastructure, Veeam Backup & Replication saves in the configuration database a thumbprint of the TLS certificate installed on the appliance. When Veeam Backup & Replication connects to the appliance, it uses the saved thumbprint to verify the appliance identity and to avoid the man-in-the-middle attack. For details on managing TLS certificates, see the Veeam Backup for AWS User Guide, section TLS Certificates.

If the certificate installed on the Veeam Backup for AWS appliance is not trusted, Veeam Backup & Replication will display a warning notifying that secure connection cannot be guaranteed. You can view the certificate and click Continue — in this case, Veeam Backup & Replication will remember the certificate thumbprint and will further trust the certificate when connecting to the appliance. Otherwise, you will not be able to proceed with the wizard.
