Can Azure Backup server be installed on same server as workload?
是否可以在与工作负载相同的服务器上安装 azure 备份服务器，还是需要单独的服务器？
是否支持备份SQL 2014 Express 版？
好像需要单独的服务器，参考这个article。
Azure Backup Server is designed to run on a dedicated,
single-purpose server. You cannot install Azure Backup Server on:
- A computer running as a domain controller
- A computer on which the Application Server role is installed
- A computer that is a System Center Operations Manager management server
- A computer on which Exchange Server is running
- A computer that is a node of a cluster
对于SQL服务器的支持的版本，您可以参考Azure Backup Server protection matrix。
