Notes

Veeam Agent Computer

Veeam Backup Server

TCP

10001

Default port used by Veeam Agent for Microsoft Windows operating in the standalone mode for communication with the Veeam Backup server.

Data between the Veeam Agent computer and backup repositories is transferred directly, bypassing Veeam backup servers.

Veeam Agent Computer

TCP

9395+,
6183+

Ports used locally on the Veeam Agent computer for communication between Veeam Agent components and Veeam Agent for Microsoft Windows Service.

If the default port number is already in use, Veeam Agent for Microsoft Windows Service will try to use the next port number.

Veeam Update Notification Server (autolk.veeam.com)

TCP

443

Default port used to download information about available updates from the Veeam Update Notification Server over the Internet.

Communication with Veeam Backup & Replication Repositories

Veeam Agent Computer

Linux server performing the role of a backup repository

TCP

22

Port used as a control channel from the Veeam Agent computer to the target Linux host.

TCP

2500 to 3300

Default range of ports used as data transmission channels. For every TCP connection that a job uses, one port from this range is assigned.

Microsoft Windows server performing the role of a backup repository

TCP

49152-65535

Dynamic RPC port range. For more information, see this Microsoft article.

TCP

2500 to 3300

Default range of ports used as data transmission channels. For every TCP connection that a job uses, one port from this range is assigned.

Shared folder CIFS (SMB) share

TCP
UDP

137 to 139,
443,
445

Ports used as a transmission channel from the Veeam Agent computer to the target CIFS (SMB) share.

Ports 137 to 139 are used by backup infrastructure components to communicate using NetBIOS.

Port 443 is used to connect the target CIFS (SMB) share over QUIC. For more information, see this Microsoft article.

Gateway Microsoft Windows server

TCP
UDP

137 to 139,
445

If a CIFS (SMB) share is used as a backup repository and a Microsoft Windows server is selected as a gateway server for this CIFS share, these ports must be opened on the gateway Microsoft Windows server.

Ports 137 to 139 are used by backup infrastructure components to communicate using NetBIOS.

TCP

49152-65535
