You received a health alert: “One or more services are not running” in dashboard, it indicated that Windows Server Addins Infrastructure Service, Windows Server Identity Management Service and Windows Server Server Backup Service are not running.
In the meantime, following exception will be found in the log file C:\ProgramData\Microsoft\Windows Server\Logs\SharedServicesHost-SystemServiceConfig.log

The exception is happening when the backup service is trying to retrieve backup history from event logs. The volume number is used as index for the search. If there is a duplicated volume name, for example “local drive”, the Backup service will not handle it properly.
Assign a unique label to each volume on the server. This ensures future backup service will succeed.
Note, after removing the event logs, you will see the “No backups available” message on server backup properties page Keep in mind that your existing backups are not lost and you can still select them during restore.. If you want to view the existing backup list, you can launch the application Windows Server Backup from the server and select “View details” for All Backups.
