Managing CBT Driver

To increase the speed and efficiency of incremental backups of managed servers, you might need to install the CBT driver. The driver is installed on every server machine protected with Veeam backup agent.

The CBT driver keeps track of data blocks that changed since the latest backup session. Information about changed data blocks is registered, and when a backup job runs, Veeam backup agent uses this information to find out what data blocks have changed since the last run of the job, and then copies only changed data blocks from the disk.

Managing CBT Driver Note:

You can install the CBT driver on managed computers that meet all of the following requirements:

  • Computers must run Microsoft Windows Server OS.
  • Computers must have Veeam backup agent 2.1 or later installed.
  • Veeam backup agent must be configured to run in the Server operation mode. For details, see Selecting Product Edition.
