Ports
To enable proper operation of Veeam Plug-in for Microsoft SQL Server, make sure that the following ports are open.
Microsoft SQL Server
The following table describes network ports that must be opened to ensure proper communication of the Microsoft SQL Server and backup infrastructure components.
From | To | Protocol | Port | Notes |
|---|---|---|---|---|
Microsoft SQL Server where Veeam Plug-in is installed | Veeam Backup & Replication server | TCP | 10006 | Default port used for communication with the Veeam Backup & Replication server. Note that data between Veeam Plug-ins and backup repositories is transferred directly, bypassing the Veeam Backup & Replication server. |
Backup repository server or gateway server* | TCP | 2500 to 3300** | Default range of ports used as data transmission channels. For every TCP connection that a backup process uses, one port from this range is assigned. | |
Microsoft SQL Server (localhost) | TCP | 6791+, | Local connections between Veeam Plug-in and source Data Movers. If port 6791 is occupied, the succeeding port numbers will be used. |
* For NFS share, SMB share repositories, and Dell Data Domain, HPE StoreOnce deduplication storage appliances, Veeam Backup & Replication uses an auxiliary backup infrastructure component — gateway server. For details, see the Gateway Server section in the Veeam Backup & Replication User Guide.
** This range of ports applies to newly added backup infrastructure components. If you upgrade to Veeam Backup & Replication 10.0 from earlier versions of the product, the range of ports from 2500 to 5000 applies to the already added components.
Backup Repositories and Gateway Servers
Depending on the type of backup repositories that you use for Veeam Plug-in backups, the following ports must be open to allow communication between backup infrastructure components.
From | To | Protocol | Port | Notes |
|---|---|---|---|---|
Veeam Backup & Replication server | Backup repository server or gateway server* | TCP | 2500 to 3300** | Default range of ports used as data transmission channels. For every TCP connection that a backup process uses, one port from this range is assigned. |
Direct Attached Storage | ||||
Veeam Backup & Replication server
| Linux server used as a backup repository or gateway server | TCP | 22 | Port used as a control channel from the Veeam Plug-in server to the target Linux host. |
Microsoft Windows server used as a backup repository or gateway server | TCP UDP | 135, | Ports used as a management channel from the Veeam Plug-in server to the Repository/Gateway server. Also, the ports are used to deploy Veeam components. | |
TCP | 6160, | Default ports used by the Veeam Installer Service and Veeam Data Mover Service | ||
Network Attached Storage | ||||
Gateway server (specified in the SMB share repository settings) | SMB server | TCP | 445 | Default port used by SMB transport protocol. |
TCP UDP | 135, | SMB/Netbios name resolution for SMB protocol (needed in some cases). For details, see the Used Ports section in the Veeam Backup & Replication User Guide. | ||
Gateway server (specified in the NFS share repository settings) | NFS server | TCP UDP | 111, | Standard NFS ports used as a transmission channel from the gateway server to the target NFS share. |
Dell Data Domain | ||||
Veeam Backup & Replication server | Dell Data Domain For more information, see this Dell KB article. | TCP | 111 | Port used to assign a random port for the mountd service used by NFS and DDBOOST. Mountd service port can be statically assigned. |
TCP | 2049 | Main port used by NFS. To change the port, you can use the nfs set server-port command. Note that the command requires SE mode. | ||
TCP | 2052 | Main port used by NFS MOUNTD. To change the port, you can use the nfs set mountd-port command. Note that the command requires SE mode. | ||
HPE StoreOnce | ||||
Veeam Backup & Replication server | HPE StoreOnce | TCP | 9387 | Default command port used for communication with HPE StoreOnce. |
9388 | Default data port used for communication with HPE StoreOnce. | |||
ExaGrid |
|
|
|
|
Veeam Backup & Replication server | ExaGrid | TCP | 22 | Default command port used for communication with ExaGrid. |
Quantum DXi |

|
Veeam Backup & Replication server | Quantum DXi | TCP | 22 | Default command port used for communication with Quantum DXi. |
* For NFS share, SMB share repositories, and Dell Data Domain, HPE StoreOnce deduplication storage appliances, Veeam Backup & Replication uses an auxiliary backup infrastructure component — gateway server. For details, see the Gateway Server section in the Veeam Backup & Replication User Guide.
