Live updating of a changed block tracking (CBT) driver. In one example embodiment, a method for live updating of a CBT driver may include loading a CBT driver into a running operating system and then performing various acts without rebooting the running operating system. These acts may include tracking, using the CBT driver, writes to blocks of a source storage, loading an updated CBT driver into the running operating system with the updated CBT driver having a different name than the CBT driver, handing over the tracking of writes to blocks of the source storage from the CBT driver to the updated CBT driver, and tracking, using the updated CBT driver, writes to blocks of the source storage.

In one example embodiment, a method for live updating of a CBT driver may include loading a CBT driver into a running operating system and then performing various acts without rebooting the running operating system. These acts may include tracking, using the CBT driver, writes to blocks of a source storage between a first snapshot time and a second snapshot time, loading an updated CBT driver into the running operating system with the updated CBT driver having a different name than the CBT driver, handing over the tracking of writes to blocks of the source storage from the CBT driver to the updated CBT driver at a handover time, and tracking, using the updated CBT driver, writes to blocks of the source storage between the handover time and the second snapshot time.
