Solution

Firstly, make sure the user that you are running the backup job as, has the correct rights! Also set it up as DOMAIN-NAME\Username. If you have selected application award processing, make sure that user has the appropriate rights (or an additional user is added for applications like SQL, Oracle etc.)

Go to the properties of the job, Guest Processing > Credentials.

Veeam Backup Credentials

Select the server producing the error > Set User > Standard Credentials > Select the appropriate user > OK > OK.

Veeam Backup Application Credentials

Then use the “Test Now” button, and ensure the authentication works correctly.
