The following network ports must be opened to ensure proper communication of the Veeam backup server with the VM guest OS system during application-item restore.
From | To | Protocol | Port | Notes |
Machine running Veeam Explorer (this can be Veeam backup server or standalone console) | Microsoft SQL VM guest OS | TCP | 1433,1434 and other | Port used for communication with the Microsoft SQL Server installed inside the VM during application-item restore. Exact port numbers depends on configuration of your Microsoft SQL server. To learn more, see http://msdn.microsoft.com/en-us/library/cc646023.aspx#BKMK_ssde. |
UDP | 1434 | Port used by Microsoft SQL Server Browser Service. To learn more, see https://technet.microsoft.com/en-us/library/ms181087(v=sql.130).aspx. | ||
TCP | 1025 - 1034 | Default RPC port range for the runtime component installed on target or staging server guest OS to support restore operations in most scenarios. Port is open only during application item restore (Veeam Explorer session). To learn how to modify default port range, see How It Works section of the Veeam Explorers document. |
The following table describes range of ports opened by Veeam Backup & Replication for iSCSI traffic during restore to the original VM. See How It Works: Mount Operations for details.
From | To | Protocol | Port | Notes |
Target remote machine to which application items are restored, | Mount server associated with the backup repository | TCP | 3260 - 3270 | Range of ports opened by Veeam Backup & Replication for iSCSI traffic during restore to the original VM. See How It Works: Mount Operations for details. Ports are open only during application item restore (Veeam Explorer session). |
