Every engineer faces a similar philosophical challenge when designing a product, no matter the product is a car or a software. For example, to make a car go faster, you need a more powerful engine but more powerful engine consumes more fuel. To save fuel, you need to make the engine smaller but smaller engine produces less power. Therefore, better engine design is the one that improves the balance of these opposing factors. The same thing for the Rollback Rx design, there are opposing factors of restoring speed and disk space consumption.The new Rollback Rx kernel design gives us the best of both worlds: Fast Restore Mode and Space Saving Mode. When you are in the Fast Restore Mode, The kernel drivers give priority to restore speed. It utilizes as much disk cache as possible and it simplifies as much disk IO as it can. While in the Space Saving Mode, the kernel drivers give priority to disk space consumption and system stability. It uses less disk cache and focuses on disk IO stability as the priority.More importantly, you can switch between the modes seamlessly. Rollback Rx will automatically switch the kernel to the Fast Restore Mode when you are restoring a snapshot.You can manually switch from Fast Restore Mode to Space Saving Mode or you can configure program settings to automatically switch to Space Saving Mode when creating a new snapshot or if the system has not been restored in X amount of time.If you have any questions please let us know.
