Installing Veeam CBT Driver IMPORTANT

Consider the following:

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.
