If the occasion arises that requires a restart of your Veeam backup server, you can try restarting the Veeam services to avoid restarting the host server.

Open Powershell as Admin and use the following commands:

Get-process | where {($_.Name -like “Veeam*”)} | stop-process -Force
Get-Service | where {($_.Name -like “Veeam*”)-and ($_.Status -eq “Running”)} | Stop-service -Force
Get-Service | where {($_.Name -like “Veeam*”)-and ($_.Status -eq “Stopped”)} | Start-service
