Step 7. Configure SMB3 Shares

After you have added a Microsoft SMB3 server, you can configure the following settings for shared folders hosted on this server:

Before you specify settings for a Microsoft SMB3 server, you must perform a rescan operation for shared folders on this server. During the rescan operation, Veeam Backup Free Edition retrieves information about shared folders that are currently hosted on a Microsoft SMB3 server, updates the list of shared folders and writes this information to the Veeam Backup Free Edition database.

Veeam Backup Free Edition automatically rescans the list of shared folders once a day. You can also start the rescan operation manually:

  1. Open the Files view.
  2. In the inventory pane, click SMB Servers.
  3. In the working area, select the Microsoft SMB3 server and click Rescan on the ribbon. Alternatively, you can right-click the necessary Microsoft SMB3 server in the working area and select Rescan.

Changed Block Tracking Settings

By default, Veeam Backup Free Edition enables changed block tracking for processing all VMs that reside on shared folders hosted by a Microsoft SMB3 server. You may disable changed block tracking, for example, for testing purposes.

Change block tracking is enabled and disabled at the level of a Hyper-V host. To disable changed block tracking:

  1. Open the Files view.
  2. In the inventory pane, click the SMB Servers node.
  3. In the working area, select the Microsoft SMB3 server and click Manage Volumes on the ribbon. Alternatively, you can right-click the necessary Microsoft SMB3 server in the working area and select Manage Volumes.
  4. In the Manage Volumes window, select the Disable changed block tracking for this host check box.

Step 7. Configure SMB3 Shares 

Shared Folder Settings

You can specify the maximum number of concurrent Hyper-V snapshots that must exist for a shared folder hosted by a Microsoft SMB3 server.

To specify shared folder settings:

  1. Open the Files view.
  2. In the inventory tree, click the SMB Servers node.
  3. In the working area, select the Microsoft SMB3 server and click Manage Volumes on the ribbon. Alternatively, you can right-click the necessary  Microsoft SMB3 server in the working area and select Manage Volumes.
  4. Select the necessary shared folder in the list and click Edit.
  1. By default, tasks working with the same shared folder can take up to 4 snapshots of a folder simultaneously. If necessary, you can increase or decrease the number of snapshots that can exist at the same time. It is not recommended to increase the number of snapshots for slow storage: a great number of snapshots existing at the same time may cause VM processing failures.
