I noticed VBR v12 RTM removed the " Install a new instance" selection from the Installation setup with the Microsoft SQL Server.
An error message will pop up if the Microsoft SQL Server or Microsoft SQL Server Express does not install locally or remotely.
That means I need to install Microsoft SQL or SQL express before installing Veeam Backup and Replication manager server (I knew v12 supports PostgreSQL) if I would like to work with Microsoft SQL? or is it a bug?
