we need below requirements to be met for application aware backups to work. It will find out the application running inside the VM and then push install the required plug-ins inside the VM.
The CommServe system, VSA proxies, and the virtual machine running the application must be able to communicate with each other.
Remote Installation Requirements
During backups, application plug-ins are pushed to guest VMs running the corresponding applications.
To enable remote installs, see Prerequisites for Installations Using the CommCell Console.
To ensure that the CommServe host can communicate with virtual machines running applications, ensure that ports are opened for the first application aware backups as described in Review Firewall and Network Port Requirements.
For Windows computers, the following ports must be opened temporarily during the remote installation:
- Port 135 for DCOM (Distributed Component Object Model).
- Port 139 for NetBIOS Session Service (if you are using legacy Windows computers, such as Windows NT or earlier versions).
- Port 445 for SMB (Server Message Block) file sharing.
- Your Windows Management Instrumentation (WMI) port. For instructions on setting up a fixed port for WMI, see Setting Up a Fixed Port for WMI on the Microsoft website.
Important: If Windows Firewall is enabled on the computer, the following ports must be open in Windows Firewall:
- Port 135 for DCOM-In (COM + Network Access).
- Port 445 for SMB.
- WMI port.
- Important: After you install the software and configure firewall settings on the client, the only port that should remain open is the firewall tunnel port (8403 by default).
