Review the Services (services.msc) running on the Veeam Backup Server and associated managed servers (proxies, repositories, etc.), and set the services to 'Log On As' Local System. This is the default configuration for all Veeam named services.
The only exception to using the Local System account for running the Veeam named services is when the VeeamBackup configuration database is located a SQL Server other than the Veeam Backup Server. In such a configuration, only the following services are modified to use a domain account to allow access to the configuration database on the remote SQL server:
- Veeam Backup Server RESTful API Service
- Veeam Backup Service
- Veeam Broker Service
- Veeam CDP Coordinator Service
- Veeam Cloud Connect Service
- Veeam Guest Catalog Service
