Abstract
In one aspect, a method includes configuring a kernel driver to record data block changes of a logical unit in a bit map and using the bitmap to perform an incremental backup of the logical unit. In another aspect, an apparatus includes electronic hardware circuitry configured to configure a kernel driver to record data block changes of a logical unit in a bit map and use the bitmap to perform an incremental backup of the logical unit. In a further aspect, an article includes a non-transitory computer-readable medium that stores computer-executable instructions. The instructions cause a machine to configure a kernel driver to record data block changes of a logical unit in a bit map and use the bitmap to perform an incremental backup of the logical unit.
