If your Hyper-V VMs are located on SMB file shares, you can add a scale-out SMB3 cluster or a standalone SMB3 server to Veeam Backup & Replication.
To be able to work with SMB3 shares in Veeam Backup & Replication, you must meet the following requirements:
1. Make sure that your SMB3 shares are properly configured. For a full list of requirements for SMB3 shares, see the Requirements and supported configurations section at
http://technet.microsoft.com/en-us/library/jj612865.aspx.
2. Add the SMB3 server or SMB3 cluster hosting the necessary file shares to the Veeam Backup & Replication console. Otherwise Veeam Backup & Replication will not be able to use the changed block tracking mechanism for VMs residing on SMB3 shares.
3. Make sure that VMs you plan to work with are not located on hidden shares or default shares like C$ or D$. When re-scanning SMB3 file shares, Veeam Backup & Replication skips these types of shares.
To add an SMB3 server or SMB3 cluster, follow the next steps.
Step 1. Launch the New SMB3 Server Wizard
To launch the New SMB3 Server wizard, do either of the following:
• Open the Backup Infrastructure view, select the Managed servers node in the inventory tree and click Add Server on the toolbar or right-click the Managed servers node and select Add server. In the Add Server window, select Microsoft SMB3.
• Open the Virtual Machines or Files view, right-click anywhere in the inventory pane and select Add server. In the Add Server window, select Microsoft SMB3.
Step 2. Specify Server Name or Address
Enter a full DNS name or IP address of the SMB3 server. Provide a description for future reference.
The default description contains information about the user who added the server, as well as the date and time when the server was added.
Step 3. Specify Server Type
Select the type of server you want to add:
• SMB3 cluster. Select this option you want to add a scale-out SMB3 cluster to Veeam Backup & Replication.
• SMB3 server (standalone). Select this option if you want to add a standalone SMB3 server to Veeam Backup & Replication.
Note Veeam Backup & Replication supports SMB3 servers running Windows 2012 only.
Step 4. Specify Credentials
Specify credentials for the user account with local administrator privileges on the server you are adding.
• For domain user accounts, the user name should be specified in the DOMAIN\USERNAME format.
• For local user accounts, the user name should be specified in the HOSTNAME\USERNAME format.
To customize network ports used by Veeam Backup & Replication components, click Ports.
• Veeam Installer Service is responsible for deploying the Veeam Transport Service and the Hyper‑V Integration Service on the SMB3 server. By default, the Veeam Installer Service uses port number 6160.
• Veeam Transport Service is responsible for deploying Veeam agents on the SMB3 server.
The agents gather files with changed block tracking data from the SMB3 server during the backup and replication process. By default, the Veeam Transport Service uses port number 6162.
• Hyper‑V Integration Service is responsible for snapshot operations and deploying the proprietary Veeam driver that handles changed block tracking for Hyper‑V. By default, the Hyper‑V Integration Service uses port number 6163.
In the Data transfer options section of the Network Settings window, specify connection settings for file copy operations. Provide a range of ports to be used as transmission channels between the source host and the target host (one port per task) and define the size of transmitted packets. By default, the port range is 2500 to 5000. However, depending on your environment, you can specify a smaller range of ports (for example, 2500 to 2510 will allow you to run 10 concurrent jobs at a time).
Step 5. Review Components
At this step, you can review the list of components to be installed on the SMB3 server. If some of them are missing, Veeam Backup & Replication will automatically install them.
Step 6. Assess Results
At this step of the wizard, Veeam Backup & Replication will install the components on the added server in the real-time mode. Wait for the operation to complete and assess the results of server processing.
Step 7. Finish Working with the Wizard
Review the configuration information and click Finish to exit the wizard.
Step 8. Configure SMB3 Shares
After you have added an SMB3 server or SMB3 cluster, you can configure settings for hosted shares.
1. Open the Backup Infrastructure view.
2. Right-click the server or cluster in the management tree and select Shared Folders. As a result, a window with the list of shared folders hosted on the server will be displayed.
Veeam Backup & Replication automatically rescans all shares managed by the server once a day.
You can also start the rescan operation manually:
1. Open the Backup Infrastructure view.
2. Click the Managed Servers node in the inventory tree.
3. Select the necessary server in the working area and click Shared Folders on the toolbar.
Alternatively, you can right-click the necessary server in the working area and select Shared Folders.
4. In the Shared folders list, select the necessary share and click Rescan.
Veeam Backup & Replication will retrieve information about newly created and deleted shares, update the list of shares and write this information to the Veeam Backup & Replication database.
By default, Veeam Backup & Replication enables changed block tracking for processing all Hyper‑V VMs. To disable changed block tracking for VMs on shares hosted by the SMB3 server, select the Disable changed block tracking for this host check box at the bottom of the Manage shared folders window.
