You can set up Veeam Agent for Microsoft Windows to use the Veeam CBT driver instead of the default CBT mechanism. The Veeam CBT driver is a class filter driver for volume devices that helps Veeam Agent keep track of changed data blocks in a more efficient way. The driver is intended for computers running applications with large database files. The Veeam CBT driver is supported for volume-level and file-level backups.
