When you encounter a technical error it's always recommended to raise a support case immediately to get a solution asap, as our ability to troubleshoot through the forum is limited. Please, let us know your case ID once you have it for reference purposes. Also note, that according to our forum rules any topic not having a case ID will be eventually removed by forum moderators.
It doesn't affect VM backups but Veeam B&R configuration backup. Here's another thread for reference, but please continue looking into this with the help of our engineers.
