How to add Microsoft SMB3 Servers to Veeam Backup and Replication v12

Veeam Backup & Replication can perform backup, replication, and file copy operations on Microsoft Hyper-V VMs whose discs are located on Microsoft SMB3 file shares.

If a Microsoft SMB3 server or cluster is not added to the backup infrastructure, Veeam Backup & Replication cannot process such VMs using the changed block tracking mechanism.

If VMs with discs on SMB3 shared folders are registered on Microsoft Hyper-V Server 2016 or later, a Microsoft SMB3 server is not required. However, if the Microsoft SMB3 server is not added, you cannot specify the Max snapshots and latency control settings for SMB3 shared folders.


You cannot use Microsoft SMB3 shared folder as storage for VM replicas.

1. Log in to the Veeam Backup and replication manager server.

2. Open the Veeam Backup & Replication Console, and click Connect.

3. On the Home page, select Backup Infrastructure.

4. On the Backup Infrastructure page, select Managed Servers.

5. Right-click Managed Servers and select Add Server.

6. Select Microsoft Hyper-V on the Add Server Page.

7. Select SMB3 on the Microsoft Hyper-V page.

8. Enter the Microsoft SMB3 server’s full DNS name or IP address on the Name page.

9. Give a brief description in the Description field for future reference and click Next.

10. On the Type page, Choose the type of Microsoft SMB3 server you want to add and click Next.

11. Select an account from the Credentials drop-down list on the Credentials page or click Add on the right to add the credentials.

12. On the Credentials page, enter a user name in the Username field. You can also click Browse to select an existing user account.

13. Enter the password In the Password field.

14. Give a brief description in the Description field for future reference and click OK.

15. On the Credentials page, click Ports.

16. If necessary, change the network ports used by Veeam Backup & Replication components on the Network Settings page.

17. Configure connection settings for file copy operations in the Network Settings window’s Data transfer options section. Provide a set of ports for transmission channels between the source and target hosts (one port per task).

18. Select the Run server on this side checkbox in the Preferred TCP connection role section. The outside client cannot connect to the server on the NAT network in the NAT scenario. As a result, services that require external connection initiation may be disrupted.

19. Click OK.

20. Click Next on the Credentials page.

21. If you add a standalone Microsoft Hyper-V host on the Review page, specify the number of tasks the Microsoft Hyper-V host must handle concurrently in the Task limit field.

22. Click Apply.

23. Click Next on the Apply page.

24. Click Finish on the Summary page.

25. Ensure the new Microsoft SMB3 server is added.
