Installing Veeam CBT Driver

You can use the Veeam Backup & Replication console to quickly install the Veeam changed block tracking (CBT) driver on a protected computer. This operation may be required, for example, if you want to evaluate driver performance on a selected computer rather than deploy driver to all computers in the protection group at once.

If you work with computer included in a protection group for pre-installed Veeam Agents, you can install and uninstall Veeam CBT driver only from the Veeam Agent computer side. To learn more, see the InstallCBTDriver and UninstallCBTDriver sections in the Veeam Agent Configurator Reference.

Before you install the Veeam CBT driver, check the following prerequisites:

The protected computer on which you want to install the driver must run one of the following OSes:

Microsoft Windows 11 (from versions 21H2 to version 24H2)
Microsoft Windows 10 (from version 1803 to version 22H2)
Microsoft Windows Server OS that is supported by Veeam Agent. For more information, see System Requirements

The protected computer on which you want to install the driver must be powered on and able to be connected over the network.

Installing Veeam CBT Driver IMPORTANT

Prior to installing the Veeam CBT driver on a computer running Microsoft Windows Server 2008 R2 SP1, make sure that update KB3033929 is installed in the OS.

The update adds the SHA-2 code signing support that is required for verification of the Veeam CBT driver signature. Without this update installed, the OS running on a protected computer will fail to boot after you install the Veeam CBT driver. To learn more, see this Microsoft KB article.

Do not install the Veeam CBT driver on a computer running Microsoft Windows Server 2008 R2 SP1, 2012 or 2012 R2 if one or more volumes on this computer are encrypted with Microsoft BitLocker (or other encryption tool), or if you plan to use Microsoft BitLocker to encrypt volumes on this computer. Concurrent operation of Microsoft BitLocker and Veeam CBT driver may result in driver failures and may prevent the OS from starting.

Do not install the Veeam CBT driver on a computer if you plan to use devices with hardware encryption made according to the TCG Opal Security Subsystem Class Specification. Operation of the driver on such devices may lead to a crash of the operating system. To learn more about the TCG Opal Security Subsystem Class Specification, see this Trusted Computing Group webpage.
