Why is it recommended to create restore points during periods of heavy compilation?

Creating restore points during periods of heavy compilation is essential because it allows for quicker rollback in the event of errors. During significant updates or changes, such as those taking place during compilation, there is a higher risk of encountering issues or bugs that can affect the system's stability and functionality. By establishing restore points, users can easily revert to a previous stable state without the need for extensive troubleshooting or manual fixes, thus minimizing downtime and potential disruptions to services or operations.

Additionally, while ensuring updates are saved is important, merely saving updates does not provide the same level of safety against errors that restore points do. The other options, such as speeding up the indexing process or protecting against unauthorized data access, do not specifically address the immediate need for quick recovery in the case of compilation-related problems. Therefore, enabling a quick rollback on errors during compilation is a key reason for making restore points.
