When applying Veeam 9.0 update 2 I found that I had to be logged into the Veeam server as “Administrator” in order to get some of the updates to apply to the backup repository that is being used to control the tape library. When I attempted to use an account that had local admin to the system, but was not named “Administrator”, the update on the backup repository failed. It is possible that Veeam was originally installed using the Administrator account.
