Dynamic write-back to non-volatile memory

Abstract:

Embodiments of the present invention include receiving, by an operating system, a request from an application to reserve a subset of a memory allocated to the application for mirroring. The request specifies a size of the subset. A first portion of the specified size and a second portion of the specified size of the memory are reserved by the operating system for the mirroring. Data to write to the first portion of the memory is received from the application. The operating system writes the data to the first portion of the memory and initiates a background write-back process of the data to the second portion of the memory.
