Abstract
An overlay optimizer can enhance the functionality of a write filter using an auxiliary overlay. An overlay optimizer can be loaded above a write filter. Based on the configuration of the write filter's overlay, the overlay optimizer can be configured to implement a volatile or persistent auxiliary overlay and then use the auxiliary overlay to selectively cache artifacts. To minimize the likelihood that the consumption of the write filter's overlay will exceed a critical threshold, the overly optimizer can be provided a list of monitored artifacts. The overlay optimizer can employ the list to selectively move monitored artifacts from the write filter's overlay to the auxiliary overlay when the overlay's consumption reaches a threshold. The overlay optimizer may also selectively allow I/O requests generated by particular applications while redirecting I/O requests generated by other applications.
